I Beat A 2812!

Yes, this is true.

 

And this is the story.

 

In order to gain an established rating, you must play events obviously. During the time you start playing tournament games and your rating more or stabilizes, you are issued a provisional rating. This rating can wildly swing as you win and lose games.

 

In 1988 my correspondence rating was settling into a stable one. My opponent’s rating was still in wild flux before he and I started our game.

 

And this is the game.

 

A.I.-Escalante
corres. 1990
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5 (This is the Wilkes-Barre Variation, an extremely tactical and popular opening in the 1980s.  It was my favorite opening at this time as well. And it also seems to have been a favorite of my opponent as he made book move almost to the end of the game. Kenneth Williams’s pamphlet, The Real American Wilkes-Barre, published in 1979, was probably the reason for its popularity.) 5.Nxf7 (An alternate move is 5.Bxf7+. But if tactical is your M.O., then you can’t beat 5.Nxf7 for the pins, forks, checks, and sacrifices.) 5…Bxf2+ 6.Kxf2 Nxe4+ 7.Ke3!? [7.Kg1 is another move. But boldly (or maybe even recklessly) moving one’s king to the center in this variation is stronger than it appears (IMHO) as Black doesn’t have too many pieces developed and White is ahead materially.]

7…Qh4

[Black has the choice of the text move and 7…Qe7. I chose 7…Qh4 as I felt the queen was more active on this square.

Remember I mentioned this was popular opening back in the 1980s? Here two very strong players trying out 7…Qe7!? Notes are from NIC Yearbook #4.

[Black has the option of 10…O-O, letting his rook into play. However, again IMHO, the text move is stronger as it allows Black’s c8-bishop to come into play AND lay claim to the center.

The Thematic Pawn Move – Pushing the “e” Pawn

by lefthandeddragon, posted in championship, chess, games, Uncategorized

Generally, in an Indian Defence, if White can get his king pawn to e4, he gains the advantage. Preventing that should be one of Black’s chief concerns.

 
We’ll start with the Nimzo-Indian to illustrate some ideas with short games.

 
In the Classical Variation of the Nimzo-Indian (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2) Black sometimes plays …b6. This move allows Black to play …Bb7, preventing White’s pawn from moving to e4. Unfortunately, he is a move too slow.

Euwe-Colle
Amsterdam, 1928
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 b6 5.e4 Bb7 6.Bd3 (White’s bishop is on a great diagonal and is supported by the Queen on c2. Black should be wary of castling kingside as the h7 pawn is vulnerable.) 6…Bxc3+?! 7.bxc3 d6 8.Ne2 h6 9.O-O O-O 10.f4 Nbd7 11.e5 Ne8 12.Ng3 c5 13.Qe2 Qh4 14.f5 cxd4 15.Rf4 Qd8 16.cxd4 dxe5 17.dxe5 Nc7 18.Rg4 Qe7 19.Rxg7+ 1-0

We’ll now take a look at the Queen’s Gambit Declined.

Malta Ol., Nov. 1980
[D61]
1.c4 Nf6 2.Nc3 e6 3.Nf3 d5 4.d4 Be7 5.Bg5 O-O 6.e3 (Black is doing quite well here in stopping .e4.) 6…Nbd7 7.Qc2 c6 8.Bd3 h6 9.Bh4 Re8 10.O-O Nf8 11.Rad1

[11.Ne5 also worked well in Belen Miguel Fernandez-Esteban Ignacio Gonzalez de Cima, Asturias Ch. Primera B, Norena, Apr. 7 2001: 11…N6d7 12.Bxe7 Qxe7 13.f4 f6 14.Ng4 Nb6 15. c5 Nbd7 16.Rf3 e5 (On deciding on a candidate move or threat, a player should also ask if his proposed move has depth (long-term gain), a follow up plan, or if such a move also provides defense as well as attacking possibilities. Black’s threat of 17…e4 is obvious, but this move has no depth, does not provide any type of defense, and as far as we know, Black had no follow up plan.)

2019_07_18_A

17.Rg3! e4 (Black’s idea of getting HIS pawn to e4, should make equal sense as White getting his to e4. But chess is not that simple.) 18.Nxh6+! +- Kh7 19.Nf5 Qe6 20.Nxg7 Qe7 21.Nxe8 (And now White can play 22.Nxe4 and more tactics will follow.) 1-0]

 

11…Nh5 12.Bxe7 Qxe7 13.e4 (Didn’t we tell Black not to allow this move a few games back?) 13…Nf4 14.Rfe1 Nxd3 15.Qxd3 dxc4 (Just about forced as …exd5 opens lines in White’s favor.) 16.Qxc4 Bd7 17.e5 (Now if e4 is a good move for White, then e5 is even stronger.) 17…Red8 18.Nd2 b5 19.Qe2 c5 20.d5 exd5 21.Nxd5 Qh4 22.Ne4 (We’ve going to give the position a +/-, but White’s advantage is probably stronger than that evaluation.) 22…c4 23.Nd6 Ng6 24.Nxf7! Bg4?

2019_07_18_B

25.Qxg4!! (Black is lost. The game could have continued with 25…Qxg4 26.Nxh6+ gxh6 27.Nf6, but you probably figured it out.) 1-0

 

Interesting enough, in the Queen’s Gambit Accepted, White can also get the advantage with .e3 instead of .e4. An old trap goes like this: 1.d4 d5 2.c4 dxc4 3.e3 b5 4.a4 (White could also play 4.Qf3 c6 5.a4, and merely get his pawn back with the advantage.) 4…c6 (or 4…a6 5.axb5!) 5.axb5 cxb5 6.Qf3!, winning.

This trap will catch beginners and even computers.

Black, even with a better third move, still lost in this game:

Tarrasch-Kurschner
Nuremburg, 1889
1.d4 d5 2.c4 dxc4 3.e3 Bf5!? 4.Bxc4 e6 5.Qb3 Be4 6.f3 Bc6 7.Ne2 Nf6 8.e4 Be7 9.Nbc3 Qc8 10.d5 exd5 11.exd5 Bd7 12.d6 Bxd6 13.Bxf7+ Kd8 14.Bg5 Nc6 15.Ne4 Be7 16.Bxf6 gxf6 17.O-O-O Ne5 18.Nf4 Qb8 19.Qe6 Rf8 20.Nxf6 Bd6 21.Nxd7 Nxd7 22.Rhe1 1-0

 

Maybe someone will get the bright idea, of when playing Black against a known 1.d4 player, to glue the e4 pawn to the board before the start of the game, so White can’t play his king pawn to e3, e4, e5, or any other square!

BODEN’S MATE

by lefthandeddragon, posted in chess, From, games, history, queen sacrifice, Uncategorized

Boden’s Mate, also known as a Criss-Cross Mate, occurs when the two bishops mate the enemy king, with each bishop coming from an opposite diagonal from the other. What makes this sacrifice even more delightful is that is frequently preceded by a queen sacrifice.

 
The name Boden is used as he is the first player of master strength to have used this mating pattern. Or at the first to have it well-known.

And now the ending of one of Horwitz’s games.

It has proven fruitless to discover the complete score of Horwitz’s game. Can someone find the moves leading up to the mate?

Chess in Another Game

by lefthandeddragon, posted in Blitz, chess, French, history, Movies, Opening, Uncategorized

Not only do I enjoy chess, but most board games in general (but to a lesser extent, of course).

 

One of these games is Dixit, a party game in which players try to guess which your card by is using a clue that you provided. Similar to Apples to Apples or Card Against Humanity (an adult version of Apples to Apples).

 

You can’t make your clue too easy, else everyone will solve it and you get no points. And if you make your clue too difficult and no one solves it, then again you get no points. Best strategy is having one or two people solve it and you earn three points.

 

So, what does this have to do with chess? Glad you asked! Two of the cards have chess themes in their image. See below.

Dixit_1_A

Dixit_2_A

 

Let’s take the first image. I’ve played this card before, in fact twice. The first time I gave the clue, it was “Berlin, Italian, French, Swiss”. All of these are chess openings, of which one person got it. I’m proud of that clue!

 

Another time I used the clue, “Peace”, as it referred to the dove. But since the clue was spoken, it also referred to “Piece”, as something one would expect to be on a chessboard. I didn’t do as well on that image.

 

The second image is harder to find a clue that doesn’t give it immediately away. Maybe “Bobby and Lisa”, a reference to strongest female and male American players of the 1960’s. Or perhaps, “What does Alice in Wonderland and One Night in Bangkok have in common?” (they both feature chess).

 

Here I digress. If the reader wishes to use chess themes found in a movie, he (or she!) may want to watch this YouTube video, https://video.search.yahoo.com/search/video?fr=mcafee&p=chess+movie#id=2&vid=998433ab7997d2e286c6412590eef4e3&action=click

 

A few pet peeves here. One is the five-minute game of Sherlock Holmes.  Players at that time did not play five- minute games; the chess clocks could not handle the rapid oscillations of fast moving players. Players would instead use a set time of 5 seconds per move, called out by an independent arbitrator. In “Searching for Bobby Fischer”, the clocks are set for five minutes, not two minutes. The chess sets used in the movies tend not to be the sets preferred by most players – too hard to determine pieces and/or the pieces are too fragile to grab and gather them, esp. in speed chess. And finally, most of the movies use Descriptive Notation (DN), such as “Queen takes Knight”, instead of more common, and easier to use, Algebraic Notation (AN). Only Harry Potter gets it right!  

 

But back to the original post!

 

Readers! Do you have any suggestions for these two cards? Would love to hear your opinion!

A TD Story

by lefthandeddragon, posted in chess, game, tournament, Uncategorized

To become a Tournament Director (TD) in chess, it is advisable first become an Assistant Tournament Director (ATD). I’ve been both. And while I found the experience to be both interesting and enjoyable, I also knew that I didn’t have time to pursue everything in chess, so I had to concentrate more on writing (which is a BIG reason for this blog).

 

Here is a story from that experience.

 

I was working as an Assistant Tournament Director (ATD) at a National JHS Championship. My job was to walk around the tournament hall and solving small problems on the games as necessary. The players were instructed to raise their hand if they needed some help.

 

young_girl

 

Sure enough, about half-hour after they games had started, I saw a hand go up. I jogged to the board where two kids were playing. To be more accurate, there was only one kid playing; he was ahead a queen, a rook, a bishop, and several pawns. His opponent had his head on the table, and not really doing anything else other than breathing.

 

The kid who was winning said, “My opponent is asleep. Can you help?”. The rules, by the way, forbid anyone disturbing any of the players while the game is still going on. That rule appears to cover players who are awake, asleep, or in deep meditation. And I wasn’t even sure if his opponent was asleep or not (my gut feeling told me he wasn’t).

 

Now, one thing almost all kids in common is impatience. It didn’t seem fair to have the winning player have to sit there until his opponent’s clock run out (the clock indicated it would be at least another hour – they apparently started the game late).

clock_s-l1000

So, the onus was on me to solve the problem.

 

I came up with a unique solution. I spoke to the kid who was winning, and loud enough so his opponent could hear me. I told him (both of them!), “If your opponent does not wake up in the next 10 seconds, I will award the game to you.” And I started counting: “10”, “9”, “8”, and then suddenly, and miraculously, his opponent “woke up”.

 

The kid who was winning had a beaming smile while his opponent feigned waking up.

 

I told them to keep playing and wished them both good luck in their continuing game.

A Fun Story and Ending.

by lefthandeddragon, posted in chess, Endgame, Humor, UFO, Uncategorized, Winawer

A few decades ago, before the invention of laptops and chess engines, I used to study chess on a large tournament-sized set.

 
During the warm summer nights California is known for, I would set up a playing board, along with notes and books, in the backyard.

 
This particular night I had just set up the board when I noticed a bright light zigzagging in the night. My eyes followed it and for some strange reason it noticed me. And it sped towards my backyard.

 

 

UFO_1

 

 
I wasn’t frightened, more curious than anything else. It’s not every day a strange, bright, flying, object settles in my backyard.

 

It was small thing and when the door opened a tiny being emerged. It (it could have been a male, female, or animal, or robot) began to talk with me. Now since I’m not a polyglot, nor do I know any extra-terrestrial languages, I didn’t understand everything this otherly-world being was trying to say.

 

But with some hand movements I got a general idea what this entity wanted to know. It (again, I’m sure what gender this being was or if it had a gender) wanted to know what I was doing with the tablecloth (the chessboard), and the little figurines (the pieces).

 
As I am happy to share the game with others, with adults, children, pets, and now aliens, I started to teach the game to it.

 
But this visitor, like so many other beginners, was impatient, and soon fell behind in material, key squares, position, and was on the wrong end of possible checkmates.

 
So here is the diagram which we eventually reached.

2019_05_15

1.Qa1+ Kxa1 (Obviously not 1…Ka3 due to 2.Qc3+ Ka4 3.Bb5+! Kxb5 4.Qc5+ Ka4 5.a8=Q+. My space-traveling friend, being a quick learner, figured this out and avoided it. Besides, there was another point to his move.)

 

2.Kc2 (with the idea of Bd4#) 2…h1=K!

(Whoa! I started to tell him that was an illegal move. To which he replied, “Didn’t you tell me that a pawn reaching the last rank, could become any piece? And I want another king”.

I had to admit he was right. What to do now? If I leave both kings on the board, it would seem likely I would stalemate one of them, and possibly both. I looked at his smug expression. It knew the problems I faced. But then I had moment of inspiration.)

 
3.a8=K! (Now he had at least one move that didn’t result in stalemate.) 3…Kb8 (forced.)

 
4.h7 Ka8 (again forced.)

5.h8=Q mate, mate, mate!

Boring Queen’s Gambit? Try the Slav!

by lefthandeddragon, posted in chess, games, miniature, Opening, Slav

Many players, especially beginners, dislike the Queen’s Gambit. They call it boring, positional, and not fun to play, from either side! Some even wonder why this opening is not banned (due it being boing, etc.).

 

Maybe they should try the Slav. It’s tactical, full of tension and a single misstep can be fatal.

  

Here is a list of miniatures to play when you are feeling sluggish.

 

And a final game, which is not a miniature, but belongs here. You’ll see why at the end.

 

Meanwhile …  enjoy!

AN INTRODUCTION TO THE ART OF QUEEN SACRIFICES, Part 1

by lefthandeddragon, posted in chess, miniature, Opening, Queen, queen sacrifice, sacrifice, Uncategorized

Perhaps the most popular games ever published are those in which a player sacrifices his Queen. Bravery is required for that player who thrusts his most valuable piece into the fight, usually with no hope of ever recovering her.

 
In the over 500 years of chess, fewer topics have been more exciting, more spectacular, and more aesthetically pleasing to the player than when he freely sacrifices his powerful Queen. In all cases, the desired result, whether immediately or indirectly, is to gain something more valuable; the enemy King.

 

 
Basically, there are three types of Queen sacrifices.

 

 

The first type is the one made for material gain. Sometimes called a pseudo-sacrifice, the Queen is given up and won back a few moves later.

 

 

Doroshkevich-Astashin
USSR, 1967 (D24)
1.d4 d5 2.c4 dxc4 3.Nf3 Nf6 4.Nc3 a6 5.e4 b5 6.e5 Nd5 7.a4 Nxc3 8.bxc3 Bb7 9.e6 fxe6 10.Be2 Qd5 11.Ng5 Qxg2 12.Rf1 Bd5 13.axb5 Qxh2?! 14.Bg4 h5 15.Bxe6 Bxe6 16.Qf3 c6 17.Nxe6 Qd6 18.Qf5 g6 19.Qxg6+ Kd7 20.Nc5+ Kc8 21.Qe8+ Qd8 22.b6! 1-0

 

 

The Queen sacrifice for gain may turn into a mate if the opponent tries to hold on the female material.

Chernev says that spectators showered the board with gold pieces after Black’s 23rd move. Soltis says it was bettors who lost the wager on the outcome.

[O.K. Here are the variations: 24.Qxg3 Ne2+ 25.Kh1 Nxg3+ 26.Kg1 Nxf1 27.gxh3 Nd2 and extra piece wins. If White tries to hold onto the Queen, he tries loses his King. 24.hxg3 Ne2#, or 24.fxg3 Ne2+ 25.Kh1 Rxf1#.] 0-1

 

 
A second popular Queen sacrifice is another form of a pseudo-sacrifice. The sacrifice is made solely for a player to checkmate an opponent. The mate is immediate and happens most frequently in the opening, as these short games show.

 

Greco-N.N.,
Rome, 1619?
1.e4 b6 (Despite all the players who have invested 400 years to analyze and perfect this opening, this defence has remained on the sidelines of theory.) 2.d4 Bb7 3.Bd3 f5?! 4.exf5 Bxg2 5.Qh5+ g6 6.fxg6 Nf6? 7.gxh7+!! (The Queen is willing offered, an offer that cannot be ignored or declined.) 7…Nxh5 (And now the coup d’état) 8.g6mate 1-0

1.e4 e5 2.Nf3 d6 3.Bc4 [3.d4 is now considered to be the best move when facing Philidor’s Defence. But then White would miss all the fun of this classical trap!] 3…Bg4? 4.Nc3 g6 5.Nxe5! Bxd1 6.Bxf7+ Ke7 7.Nd5mate 1-0

 

Paul Morphy-Duke of Brunswick and Count Isouard
Paris, 1858
(C41)
A short classic that displays all the qualities that make up a great game; rapid development, pins, sacrifices, and slightly inferior moves by the opponent.
1.e4 e5 2.Nf3 d6 3.d4 Bg4? 4.dxe5 (Simple enough. White threatens 4…dxe5 5.Qxd8+ Kxd8 6.Nxe5, netting a pawn.) 4…Bxf3 5.Qxf3 dxe5 6.Bc4 Nf6 7.Qb3 Qe7 8.Nc3 c6 9.Bg5 b5 10.Nxb5! (The whole mating sequence begins with a Knight sacrifice.) 10…cxb5 11.Bxb5+ Nbd7 12.O-O-O! Rd8 13.Rxd7 Rxd7 14.Rd1 Qe6 15.Bxd7+ Nxd7 16.Qb8+! (And ends with a Queen deflection sacrifice!) 16…Nxb8 17.Rd8mate 1-0

 
Queen sacrifices for the checkmate may also be more involved and take a few additional moves to execute the mate.

 
Maryasin-Kapengut
Minsk, 1969
(D01)
1.d4 Nf6 2.Nc3 d5 3.Bg5 (The often neglected Veresov’s Opening.) 3…Nbd7 4.Nf3 g6 5.e3 Bg7 6.Bd3 c5 7.Ne5 O-O 8.Qf3 Qb6 9.O-O-O e6 10.h4 Nxe5 11.dxe5 Nd7 12.h5 Nxe5 13.Qh3 f5 14.hxg6 hxg6 15.Be2 d4 16.Na4 Qb4 17.f4 Qxa4 18.fxe5 Qxa2 19.Qh7+ Kf7 20.Bf6 Qa1+ 21.Kd2 Qa5+ 22.c3 Rg8
2019_04_25_A
23.Qxg6+! Kxg6 24.Bh5+ Kh7 25.Bf7+ Bh6 26.Rxh6+ (with the unstoppable threat of Rh1#.) 1-0

 

 

The third type of Queen sacrifices are those initiating King hunts. The Queen is given up so that the enemy King is brought out into the open. The checkmate, if there, comes many moves later.

 
These sacrifices differ from the mating sacrifices in that, while a mating sacrifice can usually be calculated out to the end, a King Hunt is made on a player’s belief that he can find a mate somewhere down the line. In other words, a King Hunt is made more on intuition rather than calculation.

Mating threats may occur more than once in a game. Which also means a player can sometimes a player can offer his original Queen more than once.

These games are extremely rare. After all, how many Queen sacrifices do you need once you have mated your opponent?

Chess playing computers are good at several things. They are superb at tactics, discover hidden resources if being attacked, find checkmates, and they don’t get tired.

 

Earlier today it was reported on chess.com that LCO (LeelaChessZero) won the Chess.com Computer Chess Championship. LCO is a different type of chess playing computer. It does not rely on brute strength, nor a large opening base. Instead, the program is instructed to learn from its mistakes from playing itself in thousands and thousands of games.

 

LC0 finished with a score of 167.5/300

 

Below are two games from the event.

1.e4 e5 2.d4 exd4 3.c3 dxc3 4.Nxc3 (Hiderland, back in 1970, showed how 4.Bc4 cxb2 5.Bxb2 loses to 5…d5! 6.Bxd5 Bb4+ 7.Kf1 Nf6 8.Qa4+ Nc6 9.Bxc6+ bxc6 10.Qxb4 Qd1+! 11.Qe1 Ba6+ 12.Ne2 Bxe2+ -+.) 4…Bc5 5.Bc4 d6 6.Nf3 Nf6 7.O-O O-O 8.Bg5 Nbd7 9.Nd5 c6 (No player, carbon or silicon based, would want the White knight to remain on d5.) 10.Nxf6+ Nxf6 11.Qc2 Re8 12.Rfe1 Qc7 13.Bxf6 gxf6 14.Qd2 Kg7 15.b4 Bb6 16.Rad1 Be6 17.Bxe6 fxe6 18.Qxd6 Qxd6 19.Rxd6 Red8 20.Red1 (Not 20.Rxe6 because of 20…Kf7!) 20…Rxd6 21.Rxd6 Kf8 22.Kf1 a5 23.Rd7 axb4 24.Rxb7 Ra6 25.e5 fxe5 26.Ng5 h5 27.h4 Bd4 28.Nxe6+ Kg8 29.Rxb4 c5 30.Rb8+ Kf7 31.Nxd4 exd4 32.Rc8 Ra5 33.g4 hxg4 34.h5 Kg7 35.Rc6 Kh7 36.a4 d3 37.Ke1 Rxa4 38.Rxc5 Rd4 39.Rc6 d2+ 40.Kd1 Rf4 41.Kxd2 Rxf2+ (The game is completely even as both kings can’t capture the last pawn. Adjudicated as drawn.) 1/2-1/2

Smail (2120), PRO Chess League (Pacific), chess.com, Jan. 11 2017, which continued with 11.Qd1 Nbc6 12.Nf3 b6 13.Rh4 cxd4 14.Rb1 Ba6 15.Nxd4 Bc4 16.Bxc4 dxc4 17.Qf3 Rc8 18.Nxe6+ Kg8 19.Rg4 fxe6 20.Qf6 g5 21.Bxg5 Nxe5 22.Bxh6+ 1-0] 11…Nbc6 12.Qf4 b6 13.Rf3 Nd8 14.dxc5 Qxf4 15.Bxf4 bxc5 16.Be3 c4 17.Rh3 f6 18.f4 fxe5 19.fxe5 Nf7 20.Nf3 Nc6 21.Bf4 Ke7 22.Be2 [White has a slight advantage due to the better coordination of his pieces.] 22…Rg8 23.O-O-O Bd7 24.Nh4 Kd8 25.Ng6 a5 26.Rf1 Ne7 27.Bg4 Nxg6 28.hxg6 Nh8 29.Bh5 Kc7 30.Be3 Kc6 31.Rf7 a4 32.Rhf3 Nxf7 33.gxf7 Rh8 34.Bf2 Raf8 35.Bh4 g5 36.Bf2 Rh7 37.Bd4 Rhh8 38.Rf6 Kb5 39.Kd2 Kc6 40.Ke3 Kb5 41.Kf3 Kc6 42.Kg4 Bc8 43.Bg6 Bd7 44.Kh5 [White definitely has the advantage now thanks to his advanced pawn on f7. So how does he (it?) press the advantage?]

44…Kb5 45.g3 (Excellent! White just improves his position before starting any type of attack.) 45…Rb8 46.Rf1 Kc6 47.Rf6 Kb5 (Black does not mind repeating moves. But White is not going to let the win slip away with a draw.) 48.Rf1 Kc6 49.g4 Rbf8 50.Rb1 Ra8 51.Rb4 (White continues his to improve his position.) 51…Ra6 52.Bh7! Rf8 53.Kg6 Ra5 54.Rb6+! Kc7 55.Kg7 Raa8 [The win is (relatively) easy now.]

56.Bc5 Rfc8 57.Rd6 (Black’s rook wouldn’t mind moving to h8 and attempt to activate his kingside pawns with …h5, etc. But he can’t immediately move there; 57…Rh8? 58.Bg8! +-.) 57…Rcb8 58.Bg6 Rh8 59.Kf6 Rab8 60.Ra6 Rbc8 61.Ra7+ Kc6 62.Bd6 Rcd8 63.Rxa4 h5 64.gxh5 g4 65.Rb4 g3 66.Rb1 Bc8 67.Rg1 d4 68.Be4+ Kb5 69.a4+!

(An enviable position. Most players only dream about having three pawns on the seventh rank.) 98…Bd7 99.h6 (Shall we try for a fourth pawn on the seventh?) 99…Kb3 100.Rc5 Rh8 101.h7 (Got it!)

Still, it seems that 108.Kf6 is better.] 108…Rxc8 109.f8=Q Rcxf8 110.exf8=Q Rxf8 111.Rg7 Re8+ 112.Kf6 Bc8 113.Rg8 Re6+ 114.Kg5 Rxe4 115.h8=Q Rg4+ 116.Kh5 Rxg8 117.Qxg8 Ba6 118.Qb3 Bf1 119.Qa2+ Kb4 120.Qb1+ Ka3 121.Qxf1 Kb4 (White has a forced mate, was not in time trouble with the 2 second delay, and yet Black plays on.) 122.Kg4 Kc5 123.Qd3 Kb4 124.Kf5 Kc5 125.Ke5 Kc6 126.Qd5+ Kc7 127.Qb5 Kd8 128.Kd6 Kc8 129.Qb3 Kd8 130.Qb8mate 1-0
