3. Nc3

[edit | edit source]

White defends their e4 pawn while developing a piece. White is still winning but there is potential for traps and sharp play.

Typical moves include:

  • 3...Nf6, attacking the pawn again. White can defend it with 4. d3, otherwise the tempting 4. e5? falls into a trap: Black's bishop has been surreptitiously eyeing the long diagonal and the undefended g2 square this whole time. 4...Bxg2! 5. exf6 Bxh1 6. fxg7 Bxg7 and Black is better, recovering their pawn and then some.
  • 3...a6, to kick the bishop, so that 4. Bc4 may allow ...e6 then ...d5 with tempo.
  • 3...f5?!, with the idea of deflecting the e-pawn 4. exf5 and allowing 4...Bxg2?!. This may work to rattle White, but weakens Black's kingside and White is better after 5. Qh4+, even if they give up the rook: 5...g6 6. fxg6 Bg7 (6...Bxh1?? g7#!) 7. Qg5 Bxh1 8. gxh7 Rxh7 9. Bd3!±.
