August 23, 2007

One of my favorite aspects of chess is solving chess tactics. Many books on the subject continue to fill me with endless hours of pure enjoyment.  But why do I still miss them in my tournament games? : )

Below are six positions for you to find the strongest continuation. These positions have made a memorable impression on me due to the wild solution. I suspect that unless you are a chess master (or familiar with the position) to find them quite challenging.  

The solutions will be posted on September 15  or earlier. Enjoy!

Solution no.1 One of my favorite tactical chess books of all time is Fred Reinfeld’s 1001 Winning Chess Sacrifices and Combinations. I highly recommend this widely available and inexpensive book to anyone wanting to develop their tactical skills. The wild and entertaining examples made me want to go over the book several times, and contributed to making a hopeless chess addict out of me.

1…Rxh2!!  The little point of this unexpected decoying sacrifice will be seen six moves later. 2.Rxh2  (White does not have time to play 2.Ba6 due to 2…Rxf1+) 2…Qxa3! 3.bxa3 Bxa3+ 4.Kb1 Nc3+ 5. Ka1 Bb2+  6.Kxb2 Nxd1+ 7. Kb2 Nxe3

The unexpected exchange sacrifice on the kingside is simply marvelous. Not only did Black repel White’s attack, but say, after 8.fxg5, it gives the impression this amazing sequence was all to gain a pawn!

Solution no.2 This position can be found in one of my favorite tactical chess books of all time,  the 1980 Informant edition of “Encyclopedia of Chess Middlegame Combinations”. Other editions were subsequently published and the positions/layout/and puzzle categorization keeps changing. However, I’ve always felt this edition is more simple and to the point.  The puzzles are broken into two sections of sixteen themes, and the positions seemed to have carefully been chosen to highlight their designated themes. Unfortunately it is a difficult out-of-print book to find.  

Black is extremely weak on the dark squares, and White find a way to exploit this with 1.Bh3!! Rxb1 2.Qh6+!! (Tactical theme: Attraction), 2…Kxh6 3.Bf8+ Kg5 4.h4+ Kb5 5.Be2 mate. 

 

Solution no. 3 This position is from the game between Ribli-Adorjan, Hungary 1983, and I came across it from the book “How to Think in Chess” by Jan Przwewoznik and Marek Soszynski. This is a terrific hands-on book. It contains one set of 75 positions, and another set of 120 positions for the reader to solve. These examples serve to highlight some of the concepts outlined in the book, as well as to increase awareness of the importance in developing creativity, and exploring various chess thinking methods. The authors provide an overview of different solving methods, psychological training, and various ideas on fostering a player’s creativity over the board. I am currently working my way through this highly stimulating book and hope it will make a difference in my game. 

The answer to this puzzle is the unexpected thunderbolt 1…Bf1!!

Solution no.4 It is true that one should not judge a book by its cover, but I love the old paper and smell of my two-book set “2.500 Finales” (2,500 Endings) by G.M. Kasparian. This first edition was published by Editorial Sopena Argentina in 1963. One of the first puzzles is this lovely composition by E.Cook. The solution is the almost forcing line: 1.Qf7+! Kxf7 2.gxh8(N)! 3. Ke8 3 Ng7+ Kd8 4 Nf7+ Kc7 5 Ne8+ Kc6 6 Ne5+ Kb5 7.Nc7+ Kxa5 8.Nc4 mate.

Solution no.5 This is from the game between Tigran Petrossian and Ludek Pachman (Bled 1961). Petrossian uncorked 1.Qxf6+ Kf6 2.Be5+ Kg5 3.Bg7!! The reader needed to visualize this sealing move when sacrificing the queen, otherwise the combination wouldn’t work.

Solution no.6 This highly amusing exercise from Fred’s 1001 book is perhaps the most dramatic example of the clearance theme.

1…Bb5! Vacating the first piece while simultaneously attacking both White’s queen and rook. 2.axb5 Na5-g3+ 3.Nxg3 Nxg3+ 4.hxg3 hxg3+ 5.Kg1 Rh1+ 6.Kxh1 Rh8+ 7.Kg1 Bc5+ 8.Nxc5 Rh1+ 9.Kxh1 Qh8+ 10.Kg1 Qh2 mate.

Last year’s parents BBQ turned into an interesting chess meet, and the tradition continued this year, though with less players.

Many members of my stepdad’s family enjoy playing chess which is one of the reason we often play on that day. Here we have Arthur and Jeffrey (father and son) playing their first game at the BBQ.

I did not know Garry played chess until my stepdad told me. We played a slow game, and then switched to transit chess (10 seconds per move).

My daughter and I play our own brand of chess, where we take turns grabbing a piece and putting it anywhere on or off the board.

Arthur and I played one more game, a Nimzo-Indian.  The initial moves were:
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Bd2 0-0 5.a3 Bxc3 6.Bxc3 Ne4 7.Bb4 d6 8.Nf3 Nc6 9.Bd2 Nxd2 10.Qxd2 Qe7 11.e4 e5 12.d5 Nb8 13.Be2 Bg4 14.h3 Bxf3 15.Bxf3 Nd7 16.0-0 a5 17.b4 Ra7 18.b5 b6 19.Rab1 *

Solutions

1. Take it! 1…Rxd7 2.Qxd7?? Qa1 mate.

2. 1…Rg1+! 2.Rxg1 (2.Kh2 Rg8-g2 mate) 2…Qh3 mate.

3. Generally in the opening it is best to utilize one’s move to develop a piece, than to move a developed piece again. Here 1…Nh5 attacking the Bishop on f4 loses to 2.Bxb8! Rxb8 3.Qe5 with a double attack on the rook on b8, as well as the knight on h5.

4. Here I found the most forcing move 1…e3! deflecting the Queen from the e1-h4 diagonal and play Rh4 mate. White tried 2.Rxe3 but after 2…Qxe3 Black resigned in view of 3.Qxe3 Rh4+ 4.Qh3 Rxh3 mate.

5. 1…Bd5 destroys white’s rook battery and wins the exchange (bishop for a rook) as the rook on d6 is now undefended.

6. Here I mistakenly played 1.Re1?! and after black blundered with 1…Rc8 I won the pawn with 2.Nxd7 Qxd7 3.Qxe6+ Qxe6 4.Rxe6. However, instead of 1.Re1 I could have won the pawn straight away with 1…Nc6! 2.Bxc6 Qxe6+ followed by Qxc6.

7. Black wants to destroy the pawn cover of white’s king with 1…fxg3 2.fxg3 Nxh4! 3.Nh3 Bxh3 5.Bxh3 Rxf2+  

8. 1…b3 2.axb3 a3! 3.Kc3 Kb6 4.Kc2 Kxb5 regaining the pawn, and obtaining a monster passed on a3.

9. 1…Bb2! wins white’s queen for if 2. Qxb2 white falls for Arab’s mate with 2…Qxh2+! 3.Rxh2 Rg1 mate.

10. Black has the stalemating tactical resource 1…Na3+ 2.Bxa3 Qxa2+ stalemate. If 2.Ka1 Nxc2+ 3.Kb1 Na3+ 4.Ka1 Nc2+ draws by repetition. If 2.Ka1 Nxc2+ 3.Qxc2 Qxa2+ stalemate).
