After a long and tough battle two players have reached this position. White is up a pawn, small advantage not always enough to win a game. Black would be happy with a draw and has proposed it when he made his last move. Your tasks:
a) Decide if White should accept the draw or play ahead; explain your answer
b) If you have decided to play ahead, show the best line for White

Total available points for this puzzle is 20. The answers will be published next week together with puzzle #239.
