1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. c3 dxc3 5. Nxc3 Bb4 {[#] This has generally
been regarded as the most critical response to 5.Nxc3. Black pins the knight
on c3, and prepares to swap it off and then play ...Nf6 and ...0-0.} 6. Bc4
Bxc3+ (6... d6 {is more common, which tends not to make any difference in most
cases as after 6...d6 Black's best 7th move is generally to take on c3 anyway,
but Black does have the interesting sideline} 7. Ng5 Nh6 8. O-O O-O {, where
Black is not afraid of allowing White to get Nc3-d5 in. Danish Dynamite gave
the line} 9. Nd5 Bc5 10. Nf3 {threatening Bxh6, which would force the reply ...
gxh6, dangerously exposing the black king, and then} Ng4 11. Bg5 Qd7 {and I
think White has enough compensation for a pawn here, in a situation similar to
the positions that often arise from the 5...Bc5 lines. The advance of the a
and b-pawns may cause Black some difficulties. However, this line is still
untested, and there are quite a few decent alternatives for both sides at move
9 and 10.}) 7. bxc3 d6 {Black plays this to cover the e5-square, so that if
Black plays ...Nf6, developing the knight to its best square, White can't play
e4-e5 without it involving the sacrifice of a second pawn.} 8. Ng5 {White is
well justified in moving the same piece twice in the opening here, as
attacking f7 disrupts Black's development plan.} Nh6 ({A reasonable
alternative is} 8... Ne5 {whereupon play often continues} 9. Bb3 {threatening
f4 kicking away the knight on e5 and then taking on f7, and then} h6 10. f4 {
A few recent correspondence games have led to an equal game after} hxg5 (10...
Bg4 11. Qd4 $44 {- Danish Dynamite.}) 11. fxe5 Qe7 12. Qd5 dxe5) 9. O-O O-O 10.
f4 Na5 {Black wants to kick the bishop off the a2-g8 diagonal so as to unpin
the f7-pawn and kick the knight away from g5 with ...f7-f6. However, the
knight ends up a bit offside on a5, and Black could also have considered
completing development with ...Qe7 and moving the bishop on c8.} 11. Be2 (11.
Bd3 {might be a slight improvement, with the idea of e4-e5 uncovering an
attack on h7, but White might also have envisaged the upcoming piece sacrifice
after playing Be2.}) 11... Kh8 12. f5 f6 {[#]} (12... Nc6 {bringing the knight
over to defend the king would have been safer, although the move played in the
game is not objectively bad.}) 13. Nxh7 $5 {Although I didn't believe in it
when I first looked at it, this knight sacrifice appears to be fully sound,
having examined it closely with the aid of the most recent versions of
Stockfish. It is also White's only way to be sure of keeping the initiative.}
Kxh7 14. Bh5 g5 (14... Nc6 {bringing the knight over to defend the king
appears to be Black's only other way to survive. Stockfish gives its favourite
"0.00", and a closer look reveals that it probably is a draw with best play,
but of course there is plenty of scope for both sides to go wrong in this type
of position.}) 15. fxg6+ $2 (15. h4 {trying to open lines would have given
White enough compensation for the sacrificed knight.}) 15... Kg7 {Now the king
is quite safe behind White's g6-pawn.} 16. Qd2 Ng8 17. Be2 Nc6 ({Black still
has to be careful:} 17... Kxg6 $2 18. Qd3 {gives White a winning attack.}) 18.
h4 {White threatens to support the pawn on g6 with h4-h5, so this is the right
time for Black to take the pawn.} Kxg6 19. c4 (19. Qd3 {is now met by} Ne5)
19... Ne5 20. Rb1 b6 21. Rb3 Be6 22. Rg3+ {[#]} Kf7 $2 (22... Kh7 {would have
left Black with a winning position, although White retains some attacking
chances. For example,} 23. h5 Rf7 24. h6 Qd7) 23. Bh5+ {Now White invades on
the kingside and is back to having sufficient attacking chances for the piece.}
Ke7 24. Rg7+ Bf7 25. g4 Qe8 26. Bb2 Rd8 27. g5 Rd7 28. g6 Nxg6 29. Bxf6+ Nxf6

Rxg7+ 36. Kh2 {In this endgame White has the better chances due to the outside
passed h-pawn, but with best play it's a draw, and in the game Black held the
draw quite easily.} Kd7 37. Kh3 Ke6 38. h5 a6 39. Rf5 c6 40. Kh4 Rg2 41. a3 Re2

second pawn on b2. Although taking on b2 is the most theoretically critical

it accelerates White's initiative and lead in development. Black's most
reliable ways of declining it are 5...d6 and 5...Nf6, both of which leave
White with no good alternative to 6.Nxc3, heading into lines with 5.Nxc3 d6 6.

line that John Watson thought was better for Black, but I doubt this:} 9. O-O
f6 (9... Ng4 {transposing into the game is probably superior.}) 10. Nbd2 Nf7

the centre with f4, e5 and Nd4 is good for White. Black is still two pawns
ahead, but has gone too passive.}) 12. Nxe5 Nxe5 13. Be2 Qf7 {(so far analysis
by John Watson)} 14. Qb2 {and White intends to blast open the centre with f4.})

best, e.g.} 11. Nbd2 Nge5 12. Bd5 {and the position is pretty unclear, but
with White enjoying approximately two pawns' worth of compensation.}) 11. Rd3
