This is a very unusual position. White has a huge material advantage even if black promotes one of his pawns into a Queen. It is white to move and your tasks are:
a) How was this position reached: during a game, as a possible variation from a game or an invented position? Explain your answer
b) White to move and mate in 2
c) What tactic should white use?

Total available points for this puzzle is 15. The answers will be published next time together with puzzle #338.

Puzzle #336 solution:
Game Esteban – Dominguez, Valladolid 1979. This week's best answers are by the top scorers:
a) We are in the middle game because at least both sides are developed
b) The center is closed because the pawns in the center (e4-e5, d5-d6) block each other
