Budapest gambit declined A51-A52 Budapest defence 3. d5?! · Budapest gambit declined White avoids taking the free material, but this gives Black an easy time. If White wished to sidestep the complications of the gambit, a better try was to have taken the pawn then returned it. This allows Black 3...Bc5, exerting pressure on f2. A continuation is 4. e3 d6 5. Bd3 O-O 6. Nc3. Black can solve the problem of their queenside knight by playing ...a5 and ...Na6. It is advisable for White to play e3 to relieve the pressure on f2, and prevent Black's bishop from coming to d4. Otherwise they can soon run into issues, e.g. 4. Nf3 d6 5. Nc3 O-O 6. e4? (thinking to take central space) Ng4! (threatening Nxf2 with a fork)--. One problem for White is where to play their queen's bishop: Bg5 is a blunder on account of the pressure on f2, e.g. 4. Bg5?? Bxf2+ 5. Kxf2 Ng4+ 6. Ke1 Qxg5. It can end up a "French bishop", stuck on the back rank behind the e3 pawn. 3...Bb4+ is an alternative. White may interpose with 4. Bd2 or 4. Nd2 to avoid doubled pawns. Theory table 0 Budapest gambit declined 3...Bc5 4. e3 d6 5. Nc3 O-O 6. Bd3 a5 7. Nge2 Na6 8. a3 Ng4 9. h3 Nh6 10. O-O f5 - 3. ... ... 4. Bg5?? Bxf2+ 5. Kxf2 Ng4+ 6.
