3.Nf3 was mentioned on a thread posted by an inexperienced player and I discussed it a bit then. Thought I'd give this one of my eccentric little pets a thread of its own.

1.e4 d5 2.exd5 Qxd5 3.Nf3

...is supposed to allow black to equalise easily and be inferior to the far more popular 3.Nc3, but why?

3...Bg4 is supposed to be the problem, but after 4.Be2 White is ready to castle on the kingside, while black will need to castle queenside, and neither LSB is doing anything all that productive for the time being. And all other things being equal, if there is opposite-sides castling it is the side castling queenside that often takes the greater risk.

NCO gives the following line as equal, which is all the time of day it gives to 3.Nf3:

1.e4 d5 2.exd5 Qxd5 3.Nf3 Bg4 4.Be2 Nc6 5.0-0 0-0-0 6.h3 Bxf3 7.Bxf3 Qd7 8.c3 Ne5 9.d4 Nxf3+ 10.Qxf3 Nf6

That line is from the game Short-Salov, 1997, which as it happens was won by white (although I don't dispute that after move 10 white should not have been too optimistic).

1.e4 d5 2.exd5 Qxd5 3.Nf3 Bg4 4.Be2 Nc6 5.0-0 0-0-0 6.h3 Bxf3 7.Bxf3 Qd7 8.c3 Ne5 9.d4 Nxf3+ 10.Qxf3 Nf6 11.Nd2 Qd5 12.Qe2 e6 13.Nf3 Bd6 14.Re1 Qh5 15.c4 c6 16.Qe3 Nd7 17.Bd2 Rhg8 18.b4 g5 19.Nxg5 Bc7 20.Kf1 Rg7 21.Ne4 Rdg8 22.g4 Qh4 23.Qh6 Qd8 24.Bf4 f5 25.gxf5 exf5 26.Bxc7 Rg1+ 27.Ke2 Rxe1+ 28.Rxe1 Qe7 29.Kf1 fxe4 30.Bg3 Qf7 31.Qd6 Rxg3 32.Qxg3 Qxc4+ 33.Kg2 Nf6 34.Qd6 Qf7 35.b5 Qg6+ 36.Kf1 Qf5 37.Kg1 Qg5+ 38.Kh2 Qf5 39.Re2 Qxb5 40.Qe6+ Kc7 41.Qe5+ Kd7 42.Re3 Qxe5+ 43.dxe5 Nd5 44.Rxe4 b5 45.Rh4 c5 46.Rxh7+ Ke6 47.Rxa7 c4 48.h4 c3 49.Ra6+ Kxe5 50.h5 b4 51.h6 c2 52.h7 c1=Q 53.h8=Q+ Ke4 54.Re6+ Kd3 55.Qh7+ Kd4 56.Qg7+ Kd3 57.Qg3+ Kd4 58.Qe5+ Kc5 59.Rd6 Qd2 60.Rxd5+ Qxd5 61.Qxd5+ Kxd5 62.Kg3 Kd4 63.f4 1-0

But is 8.c3 really white's best move here anyway? Since black has two squares to effect the recovery of the minor exchange on (the knight can go to d4 or e5 before taking on f3) what about getting the QB out cleanly and quickly via 8.d3 ? That should at least make it difficult for Black to exchange on f3 in any kind of hurry without white getting a decent position - bishop and queen well placed, some chance of play against black queenside, black QB is still at home - surely that's good for a +/=, at least at 2000-hack level?

Obviously 3.Nc3 is the best recommendation for an inexperienced player simply because there is plenty of theory for them to follow. But (irrespective of its surprise value which is often good for a plus if Black is not prepared for it) is 3.Nf3 really so totally harmless, and if so, why?
