a) Nc3 (not recommended: Nxe4 followed by d5 is fine for Black,
b) d3 followed by c3 or Nc3 with a closed game,
c) Ng5, trying for the Fried Liver Attack, but in many lines Black gives up material for a strong attack (4. Ng5 d5 5. exd5 Na5 or b5 or Nd4, NOT Nxd5), or d)d4 when Black can equalise as long as he avoids all the traps (he must start with exd4, NOT Nxe4).
