During a game the advantage goes back and forth from one side to the other as both players do their best to impose their wills. When one side gets an advantage, the other one looks for compensation. The more skilled the players are, the more unexpected the compensation can get. Grand Masters have no trouble playing down one or two pawns if they find compensation. Present position is from a game played between 2 Grand Masters. The last move has been 35... Qg2+. Your tasks:
a) Analyse the position and find what is the compensation Black has
b) With White to move, choose the best possible line you can think of

Total available points for this puzzle is 20. The answers will be published next week together with puzzle #209.
