A reader inquired about this photo which was taken on the set of the famous movie, “Casablanca”, back in 1942. That’s Humphrey Bogart with the white pieces and his opponent is co-star Paul Henreid. It appears to be Bogie’s move, probably after 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 Nc6 5.e3 h6 6. Bh4 g5 7. Bg3 Bb4 8. Qc2 Bxc3+ 9. Qxc3 Ne4 10. Qc2 Qf6 The idea is that Black can answer the greedy 11.Bc7 with 11…Qe7, because if White retreats the bishop with 12.Bg3, the counter-attack 12…Qb4 13.Kd1 Bc7 will cause enough trouble for the pawn. Doesn’t Henreid have the look of a man who is setting a trap? The man in the background wearing the white shirt seems concerned, like he is worried that the c-pawn is loose. The younger fellow next to him is grinning like he knows that the c-pawn is the bait. Play it again, Sam.
Stockfish thinks White is winning by 0.96 by ignoring the pawn 11. Nf3 Nxg3 12. hxg3 g4 13. cxd5 exd5 14. Ng1 Bf5 15. Qc5 O-O-O 16. Ne2 Qe7 17. Rc1 Qxc5 18. Rxc5

A few weeks back I wrote that, in the endgame, the bishop was likely to outfight the knight. At the 2018 Fall Chess Classic last week, GM Ray Robson missed the drawing variations in two games where his knights were outfought by his opponent’s bishops.
After move fifty against GM Lazaro Bruzon Batista, White has his king on h5, bishop on f1, and pawns on g3, f4, d4, and a3; and Robson has his king on e7, knight on c3, and pawns on f3, f5, e6, and b5.
After move 25 against GM Aleksey Dreev, White has his king on g1, bishop on c1, and pawns on h4, g2, f2, and a3; while Robson has the king on g8, knight on b6, and pawns on g6, e6, b7, and a7.

Connecticut Chess Magazine and Coventry Chess Club are each philanthropic enterprises by Rob Roy.
They are not governmental initiatives nor are they business endeavors.
They are private initiatives by Rob Roy, for the public good, focusing on quality of life, and on chess in Connecticut.
They should never be misconstrued to represent the State of Connecticut, the Town of Coventry Connecticut, nor with any other chess associations.
The monthly tournaments in Coventry are conducted by Rob Roy acting as an independent organizer, and not by any chess club, state chapter, nor federation.
I have never written for, nor spoken for, anyone besides myself, Rob Roy, acting as an independent chess journalist.
Rob Roy derives no material gain from these two entities, in contrast; Rob Roy suffers significant monetary loss from their operations.
