Originally posted by Winston SmithThe diference between the line I covered and the one you did is the endgame it leads to. RxR endgame or NxB endgame, with white up a pawn in both cases. I'd rather this NxB cause black's bishop wouldn't be very good. But I'm not sure if it really is a better choice.
I think I spotted another missed tactic.At move 25 you can capture the a-pawn
25.Nxa5,Rxa5? 26.Rxa5,Nxa5 27.Rxc7,Bxb5 28.Rc5 and you're up the exchange
25.Nxa5,Nxa5 26.Rxc7,Bxb5 27.Rc5 again wins the exchange
25.Nxa5,Ra7 26.Bxc6,Bxc6 27.Rxc6,Rxa5 28.Rxa5,Rxa5 29.g3(or h3) and you're up a pawn
It's actually the same as monteirof's 25.Bxc6 line.Maybe this is a bit trappier and therefore easier for the opponent to go wrong?[/b]
Anyway, with all that pressure on the queenside, white should have captured that pawn.
