Ponziani Opening, Jaenisch Counterattack

edit

3. Nf6

edit

The Jaenisch Counterattack is the most common response to the Ponziani Opening at both amateur and master level.

With 3. Nf6, Black attacks the e4-pawn. This takes advantage of White's last move, as Nc3 is no longer possible due to the pawn on c3.

White's best response is to continue with the plan of 4. d4.
