1st. I think it's okay for black to take the b4 pawn, but since he already declined the Evans Gambit, he probably didn't want the pawn a second time, letting white play c3 with tempo and then d4. The only other option really is a5, which prevent's white from playing a5.
EDIT: Oh, and also Nxe5 by white, haha. Missed that the first time I looked at the diagram
2nd. Play d4. He will have to move the bishop a FOURTH time.
Hi, just come over some repertoire in Giuoco Piano that i dunno what to do cuz it doesnt fit neither the main line nor any opening theories. it just seem as it was so fierce but i cant spot it out where it goes wrong actually >.<
