The knight on c6, in front of the c-pawn
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4 Bg7 5.Nf3 O-O 6.Bd3 Nc6 7.e5
- The mistake
- Developing …Nc6 in the Austrian Attack.
- Why it costs
- 7.e5 comes with tempo, and the knight on c6 blocks the …c5 break that is Black's only counterplay. Black ends up with a bad version of both plans: no pawn breaks and a knight that has to move again.
- Instead
- …c5 straight away, or …Na6 and …c5 next. In the Pirc the c-pawn goes first and the queen's knight goes to a6 or d7.
