[Event "AVRO"] [Site "?"] [Round "0"] [White "Reshevsky"] [Black "Flohr"] [Result "1-0"] [ECO "D81"] [Opening "Gruenfeld: Early Russian Variation"] {White accepts the isolation of his d-pawn} 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Qb3 c6 5. Nf3 Bg7 6. e3 O-O 7. Bd2 e6 8. Bd3 b6 9. O-O Bb7 10. Rad1 Nbd7 11. cxd5 exd5 {White will advance Pe4, which will leave his d-pawn isolated. However, he is counting on using the resulting extra freedom of movement and the possibility of occupying e5, to give full compensation for the isolated pawn} 12. e4 dxe4 {This isolated the d-pawn, and is possibly not the best move} ( 12... c5 $5) 13. Nxe4 Nxe4 14. Bxe4 Nf6 15. Bc2 Nd5 {The usual way to exploit an isolated pawn is not to attack it directly, but to occupy the square immediately in front of it, preferably with a Knight. Hte isolated d-pawn by no means dominates the currect position; Black has to be concerned about his poorly placed Queen Bishop and the vulnerable c-pawn} 16. Rfe1 Re8 17. Bd3 Qd7 (17... Qd6) 18. Qa4 Rxe1+ 19. Rxe1 a6 $2 { Another slight error of judgement, further weakening the Queenside} (19... Rd8 20. Qxa7 $4 Ra8) 20. Rc1 Qd6 21. Qb3 Rc8 22. a4 h6 (22... c5 {Reshevsky}) 23. Be4 Re8 24. Bxd5 $1 {An astute exchanve, which makes the central pawn position symmetrical and concedes the two Bishops - seeminly a poor strategy, but Reshevsky has seen that he will have favourable play after ne5} 24... cxd5 25. Ne5 Rc8 (25... Bxe5 26. dxe5 Rxe5 (26... Qxe5 27. Qxb6 Qe2 28. Be3 $16) 27. Bf4 Qc6 28. h3 $18) 26. Re1 Re8 27. h3 Re6 28. f4 Qe7 29. Rc1 Kh7 { Protecting the g-pawn and hoping to play ... Pf6 ousting the Knight} (29... Bf8 ) 30. Bb4 Qh4 31. Qf3 (31. Rc7 Qxf4 32. Rxb7 Qxd4+) 31... Bxe5 32. fxe5 $3 { Flohr has missed this most unlikely recapture} 32... f5 (32... Qxd4+ 33. Kh1 Kg8 34. Rc7 f5 35. Bc3 $18 {wins a piece}) 33. Rc7+ Kg8 34. Qc3 Rc6 35. Rxc6 Bxc6 36. Kh1 $2 (36. Qxc6 $1 Qxd4+ 37. Kh1 Qxb4 { White could have shortened the game by three moves}) 36... Qf2 37. Qxc6 Qf1+ 38.
