In this rapid game I played recently I played the move 18.Bf4 in order to develop a piece and attack the weak pawn on d6. During the game the other main move I was considering was Nc6 which would allow me to win the bishop pair.
I ran a blunder check with Fritz after the game (missed a neat tactic winning a piece later in the game, can anyone spot it?) and on this cursory examination Fritz seems to agree with my bishop move, perhaps considering the centralised knight to be a more valuable piece than Black's 'bad' bishop.
I'd really appreciate people's views on this. Who would have chosen winning the bishop pair and only then attacking the d6 weakness?
After making my decision I got pushed back somewhat but managed to win the endgame. Really enjoyed the game.
