Dzindzihasvili - Browne, North American Open, Rd. 6 [A34]
1 Nf3 c5 2 g3 [Move order considerations in the Reti/English complex are very important. It is well known that after 2 c4 Nf6 Browne would
head towards the Hedgehog: 3 Nc3 b6, or 3 g3 b6. But 2 g3 disallows the Hedgehog unless Black is willing to risk transposition to the King's Indian attack - 2 ... b6 3 e4. 2 g3 invites Black to occuply the center with 2
... d5 with a Reversed King's Indian in store. Browne's usual reply to 2 g3 is 2 ... g6, which can lead to an English if White plays c4, a King's Indian if White plays c4 and d4, or a Gruenfeld after 3 c3 Bg7 4 d4 cxd4
5 cxd4 d5. Browne explained that he had not fared well with 2 ... g6 against Dzindzi in the past.] Nf6 3 Bg2 Nc6 4 O-O e6 [Deciding against the King's Indian 4 ... g6 5 c4 Bg7 6 d4 cxd4 7 Nxd4 O-O 8 Nc3 Nxd4 9 Qxd4 d6.]
5 c4 Be7 6 d4 cd [Opting for a Hedgehog-type formation without the fianchetto of the Queen's Bishop. 6 ... d5 would enter the Tarrasch or the Semi-Tarrasch.] 7 Nd4 O-O 8 Nc3 a6 9 Bf4 Nd4 10 Qd4 d6 11 Qd3 Qc7 [The
pressure against d6 is very uncomfortable, but if first 11 ... Nh5 12 Be3, and 12 ... Rb8 13 Ba7! Ra8 14 Qe3, or 12 ... Qc7 13 Na4 take advantage of the weak b6 square.] 12 Rfd1 Rd8 13 Ne4!! [If 13 Rac1 (threatening 14
c5) Nh5! 14 Be3 Bd7 and Black completes his development.] Ne4 14 Be4 h6 [Better than the panicky 14 ... f5 15 Bg2 Rb8 16 e4.] 15 Rac1 g5 [A critical moment. The threat was 16 c5, and the dark-squared bishop had to be
driven away. Browne prefers weakening his kingside in the hope of later creating dynamic play to the immobilization of his center that would result from 15 ... e5. The tournament situation mandated this risky decision.]
16 Be3 Bd7 17 Qb3! [More headaches! White threatens 18 Bb6 and 18 Qxb7.] Rdb8 [The more active 17 ... Re8 fails to 18 Qxb7 Qxb7 19 Bxb7 Rab8 20 Bxa6 Rxb2 21 c5! d5 22 Rd2. With the text Black hopes to eventually expand
on the queenside, but White's 20th move will hinder those plans.] 18 Bb6 Qc8 19 Qd3 Bc6 20 b3!! [Stopping the planned freeing maneuver 20 ... Bxe4 21 Qxe4 Qc6 which now fails to 22 Qxc6 bxc6 23 Bc7 as the b-pawn is
protected. Meanwhile, the move envisions the reorganization Bb6-d4-b2 and Qc3.] a5 21 Bh7+ Kg7 [On 21 ... Kf8 22 Qc3 e5 23 c5 things start to unravel.] 22 Bd4+ Kf8! [Again refusing, for positional reasons, the
invitation to play 22 ... e5. Black's position would not be pretty after 23 Bb2 b6, although he would still be kicking.] 23 Be4 [Trying to clear a path to h7 for the queen.] f5 24 Bc6 Qc6 25 Bb2 a4?? [Hastening to
create counterplay, Black only encourages White's b-pawn to join the fray. Passive defense with 25 ... Kf7 26 Qc3 Rg8 was best. The ironic aspect of 25 ... a4 is that Black had better chances of opening the a-file by
leaving the a-pawn where it was as White may have needed to open a second front with a2-a3 and b3-b4. As so often happens when one is conducting a long and arduous defence, time pressure rears its ugly head.] 26 b4 Kf7
27 b5 Qe4 [Losing, but 27 ... Qc7 28 e4 was not much of an alternative.] 28 Qc3 f4 [On 28 ... Rg8 or 28 ... e5, 29 f3 is curtains because of 29 ... Qxe2 30 Re1.] 29 Qg7+ Ke8 30 c5! [The inevitable break. Since 30 ... d5
31 c6 is grisly, Black wants to be shown.] Bf8 31 Qg8 dc 32 Bg7 Ke7 [32 ... Qf5 loses to 33 Rd6 Rd8 (33 ... Ke7 34 Rcd1) 34 Rxe6+ Kd7 35 Rd1+ Kc7 36 Be5+ Kc8 37 Rxd8+ Kxd8 38 Rf6.] 33 Bf8+ Rf8 34 Qg7+ Rf7 35 Rd7+ Kd7 36
Qf7+ Kd6 [An unfortunate stroll, but if the king goes back Black will lose the rook.] 37 Rd1+ Ke5 38 Qg7+ Kf5 39 g4+
