Be3 {A remarkable position: each side has a doubled pawn already, and White, by his last move, declares his willingness to accept another doubling. He judege, apparently, that the open d-file and the f-file will afford him full compensation.} 10... Qb6 11. Qd2 Be6 (11... Qxb2 12. Bxc5 $3 dxc5 (12... Qxa1+ 13. Ke2 Qxh1 14. Qxd6 $18) 13.

Qe3 Qxe3+ 17. fxe3 {White has hi s wish: he has two doubled pawns against Black's one, but Black also has a backward d-pawn, and an isolated h-pawn This position compresses the ideas of "weak" pawns} 17... Rg4 $1 {Forcing White into defensive play, for the Knight move he now has to make deprives him of all play in the d-file} 18. Nd2 Rdg8 19. g3 Kd7 $1 20.

Rff1 R8h6 { White must still play his Rh1 to hold the h-pawn}) 25... R8h6 26. Kd3 d5 $1 { In chess everything is relative. Black now forces the win with the only move which permits White to rid himself of both his doubledpawns!} 27. cxd5 cxd5 28. c4 (28. exd5 Bxd5 29. e4 Rh3+ 30. Ke2 Bc6 $17) 28... dxc4+ 29.
