The goal I set for myself in bowling differs from chess in this respect: I use bowling as my principal means of exercise due to my physical needs as prescribed by my doctor. As far as chess goes, besides opening a chess book or playing the pieces and pawns around the 64-squares, I find the mental exercise often exceeds the physical element of throwing a bowling ball down the lane during team competition or practice.
Per doctor’s advice, I no longer compete in chess tournament competitions, limiting it to battling my electronic computer wizard. A former chess pal suggested to me I find a new doctor.
I came across an interesting chess battle whose opening today called the Trompowsky Attack is a short but startling example of how the great players on the world stage can fall asleep at the board.
White: GM S. Palatnk vs. Black: GM E. Geller Opening: Trompowsky Attack
1. d4 Nf6 2. Bg5 d5 3. B:f6 e:f6
An interesting try by me in a club event 30/30 Tornado was 3. f4 which led to an interesting game. Black opens the e-file in hopes of getting active but double-edged play as my reason probably to avoid it. Besides, I did not like losing a developed piece, let alone one of the bishop-pair early in the game even with a slight pawn weakness which is hard to exploit.
4. e3 Be6 5. Nd2 Nd7 6. c4 Bb4 7. c:d5 B:d5 8. Ne2 O-O
Hiding the King behind a wall of pawns. But walls can be broken down and undermined over and under.
9. Nc3 Nb6 10. a3 B:c3 11. b:c3 c5
Putting the question to the Bishop eliminates the bishop-pair. Black hits the central pawn structure and hopes to secure d5 as a block perhaps of the mobile pawn chain. White finds a sharp square count sally for the Bishop.
12. Bd3 c:d4 13. c:d4 B:g2?
Always look a gift of the Trojan War Horse brought into the enemy city as a peace offering being poison.
14. Rg1 Bc6
Perhaps Geller liked the aesthetic beauty of his forces. But notice the Rook now is on the half-open file.
15. R:g7+ K:g7 16. Qg4+ Kh8 17. Qf5 and mate next move cannot be answered.
