Black has many options here to maintain the position and keep the draw in hand. Bc6! is an interesting positional play: 31...Bc6 32.Nc4 Bb5! and white must exchange for the draw to be maintained. Then it's a pawn ending. The Black king can easily defend the loose pawns and it's a relatively safe plan. Your idea was good too.

wth r u talking about jcarp? the b pawn on b6 cant leap to b4. it has to first be advanced to b5 where with the a pawn at a5 the knight takes the b pawn

Games at the expert level are usually won by mentally wearing down the opposition or by positional mistakes. Perhaps he was hoping for the first one because this is a draw.

Another fine game. Brings back memories of the game we played awhile back Charles.

Many thanks guys!
