Wikipedia defines the horizon effect as: a problem in artificial intelligence whereby, in many games, the number of possible states or positions is immense and computers can only feasibly search a small portion of them, typically a few plies down the game tree. Thus, for a computer searching only five plies, there is a possibility that it will make a detrimental move, but the effect is not visible because the computer does not search to the depth of the error (i.e., beyond its “horizon”).


What it means, in more understandable words, is that when a chess computer finds a move, or a series of moves, that loses material, or some other advantage, it stops analyzing that move or series of moves. This can lose the game, or at least the advantage, as it fails to see a strong reply or the continuation of play that will allow it to retain or increase its advantage.

An early example of the horizon effect can be found in this game.

De Legal-Saint Brie?
France, 1750
1.e4 e5 2.Nf3 d6 3.Bc4 Bg4 4.Nc3 Nc6

5.Nxe5 Bxd1?? (There were many computers in the early 1980’s would simply take the offered queen, as it was taught that being up a queen would lead to victory and would therefore stop analyzing. This simple trap caused consternation and scorn by some players as they wanted a “serious” chess computer. By the way, this trap is known as De Legal’s mate.) 6.Bxf7+ Ke7 7.Nd5mate 1-0

A more recent example can be found in this game:

20.Bf8! (This keeps the Black’s king from escaping to the center.) 20…Kxf8 (Not 20…Rxf8 21.Qh6! +-. Best for Black is 20…Nh5 21.Rxh5 gxh5 22.Qh6 Rxf8 23.Rh1 Bg7 24.Qxh5, and now if 24…f5 25.Nf4! wins on the spot.) 21.Rxh8+ Ng8

22.Rxg8+! (The computer recommends 22.Qh6+ Ke8 23.Rxg8+ Kd7 24.Rxc8 Qxc8 25.e5 Kc7 26.exd6+ exd6, when White is obviously winning. But the text move is better as it leads to a forced mate. So why did computer miss this move? Probably because it saw that White loses the exchange and concluded that’s not a good way to proceed. So it stopped analyzing.) 22…Kxg8 23.Qh6! f6 (Black is in Zugzwang, as his king is paralyzed and he can’t get help in time. 23…d5 24.Rh1 +-) 24.Qxg6+ Kf8 25.Rh1 1-0 (25…Bg8 26.Rh8 e6 and now either 27.Qxg8+ or 27.Rxg8+ mates.)



Najdorf Miniatures

I’ve entered another Najdorf thematic tournament. This is a good way to (really) learn an opening.


There are many approaches to learning an opening. One can consult an expert in the variation (but illegal once the games begin). Another approach is to gather up the books, a board, pens, paper, and some highlighters.


My favorite approach to play over some miniatures and learn some tactics and ways to take down an opponent quickly. It saves time on studying. Extra time to take down other opponents. Plus, it’s fun!

Here are some Najdorf miniatures.


They are breathtaking in their elegance, clarity, and forcefulness. And they all begin with the moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6.

To warm up the tactic monster in you we’ll start with some games that are not exactly main line.


Markus Loeffler (2426)-J. Ramseier
Ticino Open
Mendrisio, Oct. 30 1999
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Qf3!? (Not exactly book, but White is trying to lay claim to some key squares.) 6…Qc7 7.Bg5 Nbd7 8.O-O-O b5 9.Nd5 Qa5 10.Nc6 1-0


GM Onischuk (2581)-IM Bajarani (2417)
Voronezh Master Open
Russia, June 14 2013
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Nb3!? g6 7.Be2 Bg7 8.O-O O-O 9.Re1 Nbd7 10.a4 b6 11.Be3 Bb7 12.f3 Qc7 13.Qd2 Rfe8 14.Red1 Rac8 15.Bf1 Nc5 16.Qf2 Nfd7 17.Nd4 Qb8 18.Rd2 Ne5 1-0


GM David Anton Guijarro (2631)-GM Hao Wang (2729)
FIDE World Blitz Ch.
Dubai, June 19 2014
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Qd3!? Nbd7 7.Be2 Nc5 8.Qe3 e6 9.Bd2 Be7 10.g4 d5 11.exd5 exd5? 12.O-O-O O-O 13.f3 Bd7 14.g5 Nh5? 15.f4 g6 16.Bxh5 gxh5 17.Nxd5 Re8 18.Bc3 Bg4 19.Nf5! Bxf5 20.Qe5 f6 21.Qxf5 Qc8 22.Nxf6+ 1-0

6.Rg1 is relatively unexplored and rare in OTB tournaments. Just perfect for correspondence play!


M. Mahjoob (2510)-R. Kalugampitiya (2135)
Tata Steel Team Ch.
Kolkata, India, Dec. 27 2009
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Rg1!? (White takes command of the g-file, important in many variations of the Najdorf.) 6…b5 7.g4 Bb7 8.g5 Nxe4 9.Nxe4 Bxe4 10.Qg4 Bb7 11.Bg2 Bxg2 12.Qxg2 Nd7

13.g6! e6 (Black can’t take the pawn due to 13…hxg6 14.Ne6! fxe6 15.Qxg6#. If instead Black moves his queen, then White wins material. I’ll you figure it out.) 14.gxf7+ Kxf7 15.Bg5 Qc8 16.O-O-O Ra7 17.Nxe6 1-0

Here are two more games with the interesting 6.Rg1!?.


Luis Esquivel (2212)-Neuris Delgado (2254)
G. Garcia Memorial
Santa Clara, Cuba, June 2 2004
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Rg1 e5 (A common reply to 6.Rg1.) 7.Nb3 h5 8.Bg5 Be6 9.Qd2 Nbd7 10.O-O-O Rc8 11.f4 Be7 12.f5 Bc4 13.Bxc4 Rxc4 14.Qd3 b5 15.Rge1 Qc8 16.Bxf6 Nxf6 17.Re2 Qc7 18.Nd5 Nxd5 19.Qxd5 O-O 20.f6 Bxf6 21.Qxd6 Bg5+ (22.Kb1 Rd8 23.Qxc7 Rxd1+ 24.Nc1 Rxc1#.) 0-1


Wojciech Moranda (2451)-Roman Nechepurenko (2431)
European Jr. Ch.
Herceg Novi, Sept. 2005
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Rg1 e5 7.Nb3 b5 8.g4 Bb7 9.Bg2 b4 10.Nd5 Nxd5 11.exd5 Be7 12.a3 bxa3 13.Rxa3 a5 14.Ra4 Nd7 15.Bd2 Nb6 16.Bxa5 Qc8 17.Ra2 O-O 18.Nc1 Nc4 19.Bc3 Rxa2 20.Nxa2 Qc5 21.Be4 Bh4 22.Qe2 Ra8 23.b3 Rxa2 24.bxc4 Ra3 (White faces the embarrassing 25.Bb2 Re3! -+) 0-1

The move 6.a4 leads to a slower game. But one can lose the game just as quickly.


Sevastopol, 1978
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.a4 e6 7.a5 b5 8.axb6 Qxb6 9.Be3 Ng4 10.Qxg4 Qxb2 11.Bb5 Nd7 12.Kd2 axb5 13.Rxa8 Ne5 14.Qe2 Nc4 15.Qxc4 bxc4 16.Rxc8 Kd7 17.Ra8 1-0

The move 6.Be3 is an interesting combination of tactics and strategy. It’s played by many Grandmasters. Let’s take a close look.


Perenyi-Lengyel, 1983
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 b5 7.a4 bxa4 8.Rxa4 e6 9.Bb5+ Nfd7 10.O-O Bb7 11.Bc4 Nc5 12.Rb4 Qc8 13.f4 Be7 14.f5 e5 15.f6 exd4 16.fxg7 Rg8 17.Bxf7+ Kd7 18.Rxb7+! 1-0

IM J. Peters (2572)-O. Maldonado (2275)
American Open
Los Angeles, Nov. 1995
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Be2 e6 7.Be3 Be7 8.Qd2 a6 9.O-O-O Qc7 10.f4 O-O 11.Rhg1 Re8 12.g4 Nd7 (Jack Peters suggested 12…Nxd4 13.Bxd4 e5.) 13.g5 Rb8 14.h4 b5 15.h5 b4

16.g6! (Again, the move g6. Maybe there is something to attacking with one’s own g-pawn.) 16…Nc5 17.gxf7+ Kxf7 18.Nf5! exf5 19.Bc4+ Kf8 20.Bxc5 Na5 21.Qd5 1-0

White can try to include a Keres Attack (an early g4) plan with Be3. But that idea seems risky.

I do not know what is the best response to the Keres. But I do know that …h6 is perhaps not the best response.

Let’s jump a little ahead.


The most common response to the Najdorf is 6.Bg5. It leads to fascinating combinations with many ideas. I know I will face it at least once in the tournament.

Until next time.

Boring Queen’s Gambit? Try the 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!

Swiss Gambit

Most players know of Froms’ Gambit [1.f4 e5 2.fxe5 d6 3.exd6 Bxd6 4.Nf3), with continuation of either 4…g5 (to drive away the knight) or 4…Nf6 (to defend and ready to redeploy the knight to g4 or e4)].


But White can also offer a similar gambit after 1.f4 f5 2.e4 fxe4 3.d3. This gambit is known as the Swiss Gambit. Because of its rarity, most players are not aware of it or it’s thematic ideas.


Let’s take a look the gambit after the opening moves (1.f4 f5 2.e4 fxe4 3.d3).


If Black was to take the pawn, he would be a pawn up in the game. However, it would be hazardous to do so as both of White’s bishops (after 3…exd3 4.Bxd3) would be activated and his own kingside would be vulnerable. There are two things that slow down White’s attack. The first is the f-pawn, which unlike in the From’s Gambit (which does not have such an advanced pawn), blocks the bishop from going to f4 or g5. The second thing is that Black usually plays an early 4…Nf6, to stop the h5 checks.

Now, lets look at some games.


First, Black does not have to take the pawn. But such a plan can be risky as the d3-pawn can easily capture the e4-pawn and White has a nice center, without having to sacrifice a pawn.

After the moves 1.f4 f5 2.e4 fxe4 3.d3 exd3 4.Bxd3 Nf6 5.Nf3 e6, White has three excellent choices of 6.Ng5 (A brazen attempt at an attack, probably best for a blitz game), 6.Ne5 (a more cautious and shy approach to an attack), and 6.Be3 (a developing move that allows White to castle queenside if the need arises).

Black must be willing to have doubled pawns on the e-file (after …Be6) and suffer the difficulties of his pawn structure in coordinating his pieces.] 7.Nf3 (7…Nf5 eliminates much of Whites’s pressure  after 7…Bxf5. 7.Nde2 is the more positional approach. 7.Nf3 resembles a Two Knight’s Defence, something I more familiar with.) 7…Nc6 (7…Be7 is better as it would have allowed 8….O-O after 8.Ng5.} 8.Ng5 {This position is now very similar to the Two Knight’s Defence, where Black is forced to give to give up a pawn. However, in this game, White already has the greater mobility, coordination, and the initiative.) 8…d5 9.Nxd5 Nxd5 10.Bxd5 Be6 (White has a strong tactical response to Black’s lack of development.)


11.Nxe6! fxe6 12.Bxc6+ bxc6 13.Qh5+ g6 14.Qxe5 Rg8 [Better is 14… Kf7 15.O-O (15.Bg5?! Be7 and Black’s king, despite not being able to castle, will be safe on the kingside) Bg7 16.Qf4+ Qf6 17.Qc7+ Qe7 18.Qxc6 Rhc8 19.Qa4 and White remains on top.] 15.Qxe6+ Qe7 16.Qxg8 Qxe4+ 17.Be3  O-O-O (Black’s best move; everything else loses faster.) 18.O-O Bd6 19.Qb3! (19.Qxh7? is a mistake due to 19…Be5 with the idea of …Rh8.) 19…Qe5 20.g3 h5 21.Qb6 Kd7 22.Qb7+ Bc7 23.Bf4 Qa5 (Better, but still losing is 23…Rb8 24.Rad1+ Ke7 25.Qxc6 Rb6 26.Qd7+ Kf6 27.Bxe5+ Bxe5 28.Qd8+) 24.Rad1+ Ke7 25.Bxc7!



Dutch Treats

The Dutch is an aggressive response to 1.d4. It is also extremely risky.

Here are some miniatures showing how White (and Black!) can win quickly.
