Today I would like to present you a game of a good friend of mine, the strong Ukrainian GM Andrey Sumets. This is what he wrote me:
I'd like to comment my 2 games that were played in the last rounds. In both games my opponents tried to play the King's Indian defense and in both cases I played the side lines.
Sumets,A (2618) - Stella,A (2442) [E91]
11th Bergamo Open Elite Bergamo ITA (6.3), 15.07.2012
[Sumets A]
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0–0 6.Be2 Na6 7.0–0 e5 8.d5
I believe that this move isn't the strongest one. According to Chessbase, my opponent hadn't played Kings Indian before so I supposed that he might be bad prepared to such kind moves.]
8...Nc5 9.Bg5 [Another side move, perhaps the strongest one in this position is 9.Qc2 a5 10.Bg5 h6 11.Be3 b6 12.Nd2 Bg4 13.Rae1!?
a) 13.h3?! another dubious move 13...Bd7 14.b3 Nh7 15.a3 f5 16.exf5 gxf5 17.f4 exf4 18.Bxf4 Qh4 19.Rae1 Ng5 with strong attack;
b) 13.f3?! Bd7 14.b3 Nh5 15.Rfe1?! Smirin i (15.Rfc1 f5 16.a3 Bf6! 17.Bxh6 Bg5; 15.a3 Nf4) 15...Bf6! diagram 16.Bxh6 (16.g3 Bg5 17.Bf2 Ng7 (17...f5 18.exf5 gxf5 19.f4 Nxf4 20.gxf4 Bxf4 21.Kh1 the compensation for the knight is not enough) 18.Rad1 f5 19.a3 f4 20.Kg2 h5 21.Rh1 Qc8 22.b4 axb4 23.axb4 Bh3+ 24.Kg1 Nd7 black has nothing to worry about Korobov A - Miroshnichenko E 2008) 16...Bg5 17.Bxg5 (17.Bxf8? Be3+ 18.Kh1 Ng3+!! 19.hxg3 Qxf8 20.Nf1 Qh6+ 21.Nh2 Kg7–+ black threats 22...Q:h2 23 K.h2 Rh8 or just simple 22..Rh8. White can't escape.) 17...Qxg5 with good compensation for Black 18.Bf1 (18.Nf1 f5 19.exf5 gxf5 20.a3 a4 21.b4 Nb3µ Smirin, Naumkin I - Smirin I 1995) 18...f5 19.a3 Rf7 20.Rab1 Nf4 21.b4 Ncd3–+ Wukits R - Timoscenko G 2003; 13...Bxe2 14.Rxe2 Ng4 15.Bxc5 bxc5 16.g3 h5 17.Qd3 Qd7 18.f3 Nh6 19.f4 Zilberman J - Kokarev D 2008]
9...h6! [Unfortunately for me, Andrea played quickly and probably he knew this position well. Let's see briefly another opportunities.]
[9...a5?! 10.Nd2 Qe8 11.b3 Nfd7 (11...Kh8!? 12.a3 Ng8 13.b4 Na6 14.c5 dxc5 15.b5 Nb8 16.b6 h6 17.Be3 cxb6 18.Nc4 Qd8 19.Rb1 Nd7 20.d6) 12.a3 f6 (12...f5?! 13.exf5 gxf5?

10.Bxf6 Bxf6 [Perhaps another capture isn't bad but I would recommend this move]
[10...Qxf6 11.b4 Nd7 12.Nd2 (12.Ne1!?) ]
11.b4 Nd7 12.Ne1 Bg5
A strong and logical move. Frankly speaking I wasn't happy with my position. Perhaps]
[12...a5 13.a3 Bg5 even stronger. Let's see what happened in the old game Portisch - Jansa 14.Nd3 f5 15.c5?! Sergey Dolmatov condemns this move in his commentary but who likes to play the position he offered with white?! (15.Bf3 Nf6 16.Qc2 Bd7і S. Dolmatov) 15...Nf6 16.Bf3 axb4 17.Nxb4 (17.axb4 Rxa1 18.Qxa1 Bd2 with the idea 19.exf5? Bxc3 20.Qxc3 e4–+) 17...dxc5 18.Nd3 Nd7 White has nothing for the pawn]
13.Nd3 Qe7 [I don't like this move. Perhaps black should play directly f5]
[13...f5! 14.Bf3 (14.exf5 gxf5 15.f4 Bf6) 14...Nf6 15.Qc2 Bd7 with the same ideas as in the game Portisch - Jansa]

19...Bf5 20.Qb3 e4 [I was going to play 21 Re1 and missed 21...Bh4]
21.Bh5 [21.d6 this opportunity is interesting but perhaps it is not sufficient for the equality 21...Bf6 22.Nd5 Qxe2 23.Rae1 Qh5!?

24...Bxg4? [24...exf3! It would be very difficult to find the right way 25.Bxf3 Rae8 26.d6! Re3 27.g7! Seems to be the strongest move. All lines are too complicate for human being. (27.Bd5+?!
