This week's position shows material advantage for black (Knight for a pawn) and all white pieces attacking the castled Kg8. White (to move) should win here with a very nice combination; your task requires precision and an attacking eye:
a) Find the combination and correct move order, covering all possible moves for both sides. Each correct and complete move (white + black) receives 2 points.
Total available points for this puzzle is 22. The answers will be published next time together with puzzle #298.

Puzzle #296 solution:
Game Balabanov – Sebkov, corr 1970. Cody's answer was one of the best. Bradley and Benjamin had similar answers.
"a) I think white's king more in danger because it is on an open file and it is in the center. No pieces are defending the White king.
b) The best line I can think of:"
