Nf3 Nc6 3. Nf3 Nc6 4. White can of course recapture with 4. Nc6 inserted. After Nxc3, or sacrifice a second pawn at b2 with 5. Bc4, which is more dangerous but of more marginal soundness. The idea is to open up lines for the white pieces and increase the white lead in development, which will typically be used as a basis for launching a quick attack on the black king. Bc4, which is more dangerous but riskier.
Alexander Alekhine often played 1. Nxc3 in casual games, which often transposed after a subsequent Nc6 and Nf3. The most common objection to playing this gambit is that 4. Nf6 is also quite good. Nge7 intending Bc4 d5 6. My feeling is that this gambit is less definitely sound than the Scotch Gambit 4. Bc4 , with White either having full compensation for the sacrificed pawn s or coming very close, regardless of whether 5.
Nxc3 or 5. Bc4 is played, but as the resulting positions especially after 5. Bc4 cxb2 6. Bxb2 are hard to assess, Black might be able to come out on top with very precise defence. Nf6 and the Philidor Defence Nc6 3. Bb5 transposing into the Steinitz variation of the Ruy Lopez, which is quite passive for Black , or 4. Bc4 which tends to lead into the Hungarian Defence. If White tries 1. Nc6 transposing to a line of the Nimzowitsch Defence, 1.
Nf6 4. Qd5 gives White a persistent initiative. Instead 3. Black can bring the king to comparative safety with Thus I am inclined to recommend At move 3, Bc4, which is actually how I have most commonly reached it in practice.
Nxc3 Nc6 transposing to Nxc3 Bb4. The position on the left can arise from the common sequence 4. Bc4 d6 6. Nxc3 d6 6. Bc4 Nf6 7. Qb3 Qd7. The queen move looks awkward, blocking in the bishop on c8, but as well as defending f7, it blocks possible checks on the a4-e8 diagonal and so prepares In that line White should increase the pressure on the f7-pawn with 8.
Ng5, which typically leads to board-wide chaos, but instead White has rather naively castled, 8. Another common motif is that White must often complicate matters to maintain the initiative.
The position on the left arises from 4. Nxc3 Bb4 6. Bc4 d6 7. Ng5 Ne5 8. Bb3 h6. Black gets this h-pawn push in just in time, because otherwise White is threatening 9. Black is hoping for 9. Nf3, which allows Black a relatively comfortable game, but here White can complicate matters by pressing forward with 9. It can lead to an exchange of knights, but it also opens up more lines and makes the position more crazy.
Black has to be wary of playing Nf6 without preparing it with This position is a particularly bad version for Black, arising from 4. Nxc3 Be7?! Bc4 Nf6?!. After 7. Probably the best version of this sort of line for Black is 4.
In any case, White tends to score well. If Black declines the gambit, White often ends up with an isolated pawn on d4. The diagram on the left results from the Black will typically aim to play against the potentially weak pawn on d4, and exchanges of pieces generally help Black because the pawn would prove to be a weakness in the endgame. Black can also consider castling queenside and launching a kingside attack, although this leaves the black king exposed to attack down the half-open c-file.
White will generally strive to keep pieces on the board and, after completing development, set about generating piece activity. The half-open c-file is also a useful avenue of attack for White, especially if Black boldly castles to the queenside. White will also hope to get in the d4-d5 push at some stage. Theory and Illustrative Games Accepted I: Nxc3 White settles for sacrificing just one pawn, and develops a piece in the process. In return for giving up a centre pawn, White has an extra developing move and additional open lines, which will typically be used as a basis for launching an attack against the black king.
White also has a lot of control over the important d5-square. An important justification for this gambit is that Black has difficulty with kingside development. However, …Ng8-f6 is often hit by e4-e5, and so Black tends to have to play …d7-d6 before …Nf6, and this gives White more time to try and catch the black king in the centre.
So what does Black do with the dark-squared bishop? Bc4 intending Ng5, attacking f7 immediately. Black can vary the move order with Qb3 is less likely to give enough compensation after Qxc3 Qf6 or 8.
Bxc3 8. In either case Black is preparing to castle kingside and White can only prevent this by playing a questionable second pawn sacrifice with e4-e5. An interesting deviation is 6. Bg5, aiming to put the knight on g8 into an awkward pin, and I think White can get enough compensation if Black obliges with Nge7, following up with Bc4, Qb3 and White can also consider castling queenside and throwing the h-pawn forward, although this appears to be too slow if Black plays accurately.
My main objection to 6. Bg5 is the retreat Bf8-b4-e7, appears to be very solid for Black. Qb3 7. Ng5 also attacks f7, though in view of the intricacies of the line Ne5 8. Bb3 h6 9. Qd7 8. Ng5 Ne5 9. Bb5 c6 Bc5 has mostly been under-rated.
Tame ways of declining such as Correspondingly, in the Chesslive. The line in question was introduced by Capablanca vs. Marshall, Lake Hopatcong Nc3 Bxf3 9. Bxf3 Qc4.
