Tal vs. Byrne

Tal vs. Byrne
Biel Interzonal 1976
Sicilian Defense, 4 Qxd4
1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Qxd4 Nc6 5 Bb5 White is prepared to surrender the two bishops to keep up the momentum of his development. However, this line is no regarded as very threatening for Black. 5…Bd7 6 Bxc6 Bxc6 7 Nc3 Nf6 8 Bg5 e6 9 0-0-0 Be7 10 Rhe1 0-0 11 Qd2 Preparing Nd4 followed by f3 or f4. 11…Qa5?! Not the most accurate, as after Kb1 the black queen will be exposed to Nd5 tricks. 11…Qc7 12 Nd4 Rfd8 is better, with equality. 12 Nd4 Rac8 13 Kb1
After 13 Kb1
Now 14 Nd5 is a real threat, and meeting it costs Black a tempo. 13…Kh8 If 13…Rfd8, then 14 Nd5 Qxd2 15 Nxe7+ Kf8 16 Rxd2 Kxe7 17 f4 with the awkward threat of 18 e5. 14 f4 Now White can choose whether to continue with e5 or f5, depending on Black’s response. 14…h6?! 14…Rfd8 is the best, securing the d6-pawn and preparing to answer 15 e5 by 15…dxe5 16 fxe5 Ng8. 15 h4!
After 15 h4!
Naturally, Tal does not retreat the bishop but maintains it on g5. 15…hxg5? This move is crushingly refuted. 15…Rfd8 was still the best. 16 hxg5 Nxe4
After 16...Nxe4
Black tries to exchange queens by returning the piece, but White is having none of it! 16…Nh7 fails to 17 g4 Kg8 (17…Nxg5 18 Rh1+ wins) 18 Q h2 Bxg5 19 Rh1 Bh6 20 g5 Nxg5 21 fxg5 Qxg5 22 Rdg1 and wins. 17 Qd3! Black is defenseless. 17…Bxg5 Or 17…Nxc3+ 18 bxc3 Kg8 19 Rh1 f5 20 g6, winning. 18 Nxe4 Bxe4 18…Bxf4 loses to 19 Rh1+ Bh6 20 Nf6. 19 Rxe4 Bh6 20 g4 f5 21 Rxe6 Bxf4 21…fxg4 loses to 22 Rh1 Rc7 23 Qg6 Rfc8 24 Re8+ Rxe8 25 Qxe8+ Kh7 26 Ne6. 22 Nxf5 1-0 There are just too many threats: 23 Rh1+, 23 Ne7 and 23 Qh3+, for example.
