♡ 28 ( +1 | -1 ) To answer my own question, I think I have it!
Am I right in saying they both start out the same 1.e4 e5 2. d4 exd4 3.c3 dxc3 But the difference is that in the goring gambit white recaptures immediatley with 4.Nxc3.. where as in the danish gambit white plays 4.Bc4 cxb2 5. Bxb2?
♡ 21 ( +1 | -1 ) I don't think soI could be wrong, but I always thought that the Goring gambit ran 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. c3 dxc3 5. Bc4 (the difference between the Danish being the inclusion of Nf3 and Nc6). An Nxc3, either before or after Nf3, transposes to the Scotch Gambit.
♡ 35 ( +1 | -1 ) Pirc systemsI'd say that Be3+f3+Qd2 etc. is a good way to play against Pirc, although I much used a following non-Pirc structure with good success: Bd3+c3+f4+Nf3+e5+0-0. White usually gets the f line (after ...de5 you take with f pawn) and more space, while black gets pressure against the centre with c5 and f6. It is easy to slip for both sides!
