This interesting game has just reached the middle game and both players have attacking on their mind. It is black to move. Your tasks:

b) Could you find a way for black to strike first and obtain winning advantage?

Total available points for this puzzle is 15. The answers will be published next time together with puzzle #374.

Puzzle #372 solution:
Online position. This week's best answers are by the top scorers:
a) I would not take that pawn because it (the Queen) can be easily trapped and black has not castled yet. King safety is more important
