What plans are recommended to combat:
1) d4...d5
2) e4... Nc6
I usually play the Advanced French with 3) e5
3 Nc3
3.e5
Still the same. Nc3. If dxe the push the d pawn and kick the knight.
I think Nc3 is the only sensible move. After 3.e5 it is not really French, because Black has not yet played e6. No problem for him to develop his Bc8.
