We have an equal material position with opposite side castling. It is Black to move and you need to help him out figure out how to continue. Your tasks:
a) Analyse the position and propose what each side should do
b) Come up with the best continuation you can think of

Total available points for this puzzle is 20. The answers will be published next week together with puzzle #245.

Puzzle #243 solution:
Ahrens – Dyckhoff, Germany 1937. Anya's answer:
a) The opening was 2 Knights
b) The material is even but black has an extra pawn. Black's queen is pinning the d5 bishop and white is pinning the e6 bishop with the rook. The white king already castle and the black side didn't. I think that black is better because it's Black's turn to move and he can get rid of it's own pin and can take his opponent's pinned bishop.
