Happy Thanksgiving!

Happy Thanksgiving!

 

 

Let’s first start off with the answers from last week’s simple (or maybe not-so simple) problems.

 

 

 

(1)  This one is very easy. White can only make legal moves. So, he must play 1.d4. And Black can only respond with 1… b5. The problem continues with 2.d5 b4 3.axb4 a3 4.c5, and mate cannot be avoided.

 

 

(2) Cook’s problem also can be solved with just making the only legal moves available. 1.c4 leads directly to mate. Incidentally, if it is Black to move in this position, he also mates with legal moves, starting with 1…f5.

 

 

(3) Black threatens promoting and winning with his two pawns on the seventh rank. White must therefore check to have any chances at winning.

 

 

White must play 1.bxc3+. If Black king was to step on a white square, White would immediately have winning endgame after Qb3+. Black then has to stay on the dark squares and plays 1….Kc5. And White continues with 2.cxd4+. If you can see the pattern forming you figure out the rest.

 

 

(4) Since it is White to play and win Black must have made the last legal move. But which one would let White win?

 

 

To save a little time, I’ll just mention that Black’s last move was 1…f7-f5. Now you can figure it out.

There are a number of chess tournaments being held this weekend. Perhaps the best well-known is the American Open, being held in Costa Mesa, California. See website for details:

One thing I enjoy about chess is the endless possibilities for exploration. Here is a recent blitz game, and maybe I’m wrong, but it rapidly goes into new territory.

 

 

Escalante-“GGRap”
Blitz Game
Chess.com, Nov. 23 2019
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 e6 5.Nc3 Bb4 6.Be2?!

 

[Theory recommends Nxc6 on this move or the next. Here is a game showing at least one possibility of the Nxc6.

 

Sadek (2183)-El Ghazali (2362)
Golden Cleopatra
Cairo, Apr. 7 2002
1.c4 c5 2.e4 Nc6 3.Ne2 Nf6 4.Nbc3 e6 5.d4 cxd4 6.Nxd4 Bb4 7.Nxc6 bxc6 8.Bd3 Bxc3+ 9.bxc3 Qa5 10.O-O O-O 11.Be3 Ba6 12.c5 Bxd3 13.Qxd3 Ng4 14.Rfd1 Rab8 15.h3 Nxe3 16.Qxe3 Rb5 17.Rxd7 Rxc5 18.Rb1 a6 19.Rbb7 Rxc3 20.Qf4 e5 21.Rxf7 Rc1+ 22.Kh2 1-0.

 

But I didn’t want to play it. Blitz games can help you learn more about your pet opening in two ways. One, it is a good way to try out new ideas, and two, it is a way to find out why a suggested move is usually better than one’s own idea. Here’s a game to try out a different, but not necessarily better, move.]

 

6…Nge7 7.O-O O-O 8.Be3 Bxc3 (8…d5 is better for Black as it opens lines for a possible attack.) 9.bxc3 a6 10.a4?! (OK, this move doesn’t do much other than gain space for White on the queenside. Perhaps better is still Nxc6!?) 10…Qc7 11.Qd2 d6 12.f4 f6?! (Black should keep developing with 12…Bd7. He soon falls behind in development and piece play.) 13.Rab1 e5 14.fxe5 dxe5 15.Bc4+! Kh8 16.Ne6 Bxe6 17.Bxe6 Rad8 18.Qf2 Qd6 19.Ba2 Qa3? (Black gets greedy and being behind in development category is not good for his game.) 20.Bb3!

 

2019_11_28
20…Rd7?? (Black should admit his mistake and move his queen back to d6, with White having an advantage, but not necessarily a winning one.)  21.Bc5!! (Now White has winning advantage as Black’s queen is trapped.) 21…Rfd8 22.Bxa3 Rd2 23.Qe3 Ng6 24.Bd5 Nf4 25.Qxd2 Nxd5 26.exd5 Na5 27.Qd3 1-0
