White is a pawn down but the extra Black pawn is almost irrelevant as it is a doubled and weak a-pawn. With pawns on both side of the board the White bishop is the more dominant minor piece and White also has a rook on the 7th rank so White should be better. However, Black is threatening a big fork on 2 and White's bishop is also attacked. Therefore Option C is correct as this is the only move that keeps the bishop on the board and protects e2.} 24. Bc4 $1 {Maintaining control of the 7th rank and better piece activity. England's top grandmaster now plays the endgame precisely and wins the game by creating threats on both sides of the board.} ({Option A} 24.

Re7 (26. R1c6 a5 27.

Miles is looking to fix Black's kingside pawns so they become later targets.} Nd5 33. h4 Nc3 {Black feels he can only tread water and watch Miles improve his position.} 34. h5 {Part one of Miles' plan has been completed.} Nd5 35.
