Chess Puzzle of the Week (127)

Congratulations to Mike Healey, who recently finished in second place behind England No. 1 Mickey Adams in the Drunken Knights 1st Anniversary Arena.

In this position he has white against Ginger GM Simon Williams.

It’s Simon’s move. He’s had the worst of the opening, but now has the chance to capture a pawn on a4.

Should he capture the pawn? What do you think should happen after Bxa4?

If your name isn’t Mike or Simon, do let me know what you think!
