(I believe this really belongs in the d-pawn Special forum) After 2.Bf4, 2...Nf6 is the natural choice, even though there are other interesting options (2...c6, 2...e6, 2...c5). After 3.Nf3 you reach a standard London position, which is of course fully OK for both players, but 3.e3 has its advantages. Now 3...Bf5 is considered slightly risky, as it allows White to attack b7 in some lines. But after 4.e3, your 4...e6 is a good practical choice. White's best may well be 5.c4!?, but that allows 5...Bxb1, stopping White from castling. Personally I prefer 5.Nbd2, but after 5...Bd6 6.Ne5 it may well transpose. 5.Ne5!? as played in your game may be a better practical weapon, as g4 in some lines may be a dangerous (and unexpected) move. I strongly doubt that after 5...Nbd7 6.Be2, 6...h6 is forced. 6...Be7 7.g4 Bg6 8.h4 may indeed come close to winning on the spot, but a more active move like 6...c5, planning ...Qb6 should be playable (if murky). And 6...Nxe5 7.Bxe5 Nd7 8.Bg3 Bd6 9.f4 c5 10.c3 Qb6 11.Qb3 c4 seemed at least equal for Black in Abel - J Laszlo, Hungarian Cht 1992.
