Puzzle #355 solution:
Opening theory. This week's best answers are by the top 5 scorers:
[i]a) The opening is Giuoco Piano (Italian Opening), then 4.b4 turns it to Evans Gambit
b) Although White lost 3 pawns, White is still standing better because
1. It has castled
2. It has developed his pieces
3. It has control of the center
4. It attacks the f7-weak spot
Now it is the time to start the attack
