Bxc1 Bxd5 {The extraordinary thing about this game is that Black, who up to now has been demonstrating that his own backward pawn was no disadvantage, now proceeds to show that White's backward pawn is a very great disadvantage. The isolated White d-pawn in fact shows all the characteristics of a backward pawn, but only in the negative sense.} 28. f3 Rc2 $1 29. a4 (29. Rxe5 Bxf3 30. gxf3 Rxc1 31. Qxc1 Nxf3+) 29... b4 30.
