The looks can be deceiving in this position. Material is equal and both Kings have castled long time ago in the opening. It is black to move. Your tasks:
a) Analyse the position and decide who stands better? Is black OK?
b) What plan should black put together?
c) Put together the best moves you can think of to fit the plan

Total available points for this puzzle is 25. The answers will be published next time together with puzzle #368.

Puzzle #366 solution:
Stamma 1737. This week's best answers are by the top scorers. This time all got the answers right and the small difference was made by better explanations:
a) White must find a solution because black has a mate in 1 that cannot be stopped
b) White's solution must be forcing moves (checks) ending with mate
