The game just got going and you need to pay attention to the position we have on the chessboard. You need to do that at every move to be able to understand what is happening and come up with the best answers; however this is an important position. Your tasks:
a) Guess what was the opening name and add the reason for your guess
b) Analyse the position and decide who is better
c) White to move and win; write the best line you can think of

Total available points for this puzzle is 30. The answers will be published next time together with puzzle #359.

Puzzle #357 solution:
Opening theory. This week's best answers are by the top scorers:
a) The opening is Fried liver attack
b) White has: castled, successfully trapped black's king in the center by sacrificing a knight, developed all his pieces, controls most of blacks escapes squares, has 2 passed pawns (e- and d-) and has a rook on the open f-file
c) Black has: not been able to castle, 2 pieces are not developed, up material, ran all the way back to e8, and wants to trade pieces hoping it would slow down white's attack
d) White can win because: all its pieces are ready for attacking, black's king is stuck in the center (which is open) and black has no support for the king
