<2. Bg5> The Trompowsky Attack. Why does McShane play this minor line to 1.d4? Well his opponent Vasilios Kotronias is a noted opening specialist and expert on the Kings Indian Defense. By playing 2. Bg5 McShane avoids mainline KID theory, since if Black now plays 2...g6 White has the thematic Bxf6!.

<2...Ne4> might look weird but by playing this move Black avoids Bxf6 and gains a tempo on the bishop. The downside is that the knight might get kicked away by f3 later.

<3...c5> Black challenges the center and prepares Qb6 attacking b2.

<5. Bc1> Defends the b2 pawn. Since Black's knight is vulnerable in the center this retreat is justified. 5. Nd2 Qxb2 is better for Black.

<5...g6> Prepares Bg7 attacking b2.

<6...Nd6> The knight is better here since now f5 can be played in order to break up White's pawn center.

<8. Nc3> Supports the center and cuts off the attack on b2.

<9.exf5> McShane has a specific idea in mind. First he lures the knight off the d6 square.

<10. g4> Then he lures it away from the defense of the d6 square.

<11. d6> The pawn cannot be taken. If 11...exd6 Qe2+ Kf8 Nd5 and 11...Qxd6 Qxd6 exd6 Nd5 .

<12. Nb5> Threatens a nasty fork on c7.

<13. Bf4> Develops the bishop and overprotects d6.

<13...Qc6> Threatens Nxg4 with a pin on the h1 rook. It might be that the immediate 13...Nxg4 is better fxg4 Qc6 Qf3 O-O.

<14. Bxh6> Removes that threat.

<16. h4> White's starts a kingside attack. The threat is h5.

<18. Ke2> The king might look exposed on e2, but Black really has no way of attacking it.

<18...Nb4> The threats are a6 and Nd5.

<19. hxg6> White ignores Black's threats and proceeds with his attack.

<19...h6> Black wants to keep the h-file closed.

<20. g7> If Rxh6 immediately then Rxf3 Nxf3 Qe4+ Kd2 Bf4+ forking king and rook. If Qd2 then same idea Rxf3 Nxf3 Qe4+ and now White's king has to retreat to d2 since White's queen occupies d2 and Qxf3. g7 is excellent since if now Rxf3 Nxf3 Qe4+ Kd2 White's queen defends f3 and there's no fork from the Black bishop.

<21. Qd2> Attacks h6 and prepares Qc3.

<23. a3> Removes the defender of the d3 square.

<24. Qg3> Threatens Qg6+.

<26...b6> Intends Bb7.

<27. Rhg1> Prepares f4 which wasn't possible immediately because of Qxg2+.

<27...Bf4> Stops any ideas of f4 but vacates the a1-h8 diagonal.

<I watched th[is game] and, about move 12, asked @Tiviakov what he thought of this fine example of the "English School of Chess". He said, "In Soviet Union, if you played like this, the coaches would have cut off your hands!>
