Black has found out the hard way two Bishops are better than a Rook and a pawn. White is threatening mate in 1 and it does not look like black can stop it, even if it is his turn to move. Your tasks:
a) What should black do?
b) Put together the best line for black you can think of

Total available points for this puzzle is 20. The answers will be published next time together with puzzle #372.

Puzzle #370 solution:
Game Krnak – Sipkovsky, 1993. This week's best answers are by the top scorers:
a) I think White is down a rook for 2 black pawns and he did this to open up the position of Black's king and to block up his defenders.
b) Black's king safety is really weak because it has no defenders like the pawns who got traded off for the rook. White's back rank is weak but there are no attackers. Black's two rooks and queen is neither that active nor defending the king so might as well give him 1 for value. For black,he should bring more defenders to his king.
All of white's pieces are active since White is down material. White's queen is so powerful because it's right beside black's king. White must be really aggressive because he is down material.
