I don't play Queen Pawn's opening.So I will move what usually my opponent moves.
I vote 2.c4
It's scary in Event Chess, since things can change on a thin dime. Notice that Martin brought his Knight out immediately… he knows how his toast is buttered. Two pawns forward for us is scary.
Lemme count the votes:
2.Nc3 2 votes
2.d4 2 votes
