You can follow his comments below;


The overall winners of both sections had been almost defined in this round – a rare situation with one round still to go, I have to admit, especially for the Swiss tournament. While first board of an open section saw decisive result, I wouldn’t really comment this one as it seems to be too long and complicated to get the full picture, while White’s unlucky play in a time trouble is fairly obvious. So, take a look on another examples, picked for you by your trulyJ

Wei, Yi - Ipatov, Alexander

1.e4 e5 2.Nf3 Nf6 3.d4 Nxe4 4.dxe5 d5 5.Bd3 Be7 6.0–0 Nc5 7.Be2 0–0 8.Be3 c6 9.c4 dxc4 10.Bxc4


10...Be6 A novelty, although it seems White gets an advantage after this move. Both [10...Nbd7; and 10...Qxd1 seem to be fine for Black.] 11.Bxc5! Straightforward way to get an advantage - White will benefit from having better pawn structure as well as an outpost on d6. 11...Bxc5 [Worse would've been 11...Bxc4? 12.Qxd8 Bxd8 13.Rc1! where Black just loses an exchange.] 12.Bxe6 fxe6 13.Nc3 Na6 14.Ne4 h6?! It doesn't seem to me this move had to be played right there, so I would consider to start with [14...Qe7] 15.Qe2 Qe7 16.Rac1 [Perhaps more would've offer 16.Rad1 Rad8 17.a3 Rd5 18.g3 , preparing Nh4, with better prospects.] 16...Rad8 17.Rc4


17...Bb6?! [Better was 17...Rd5 , defending the bishop and releasing the queen.] 18.Nd6 Strictly speaking, this is not a mistake, as Black doesn't have any options but to repeat. 18...Bc5 19.Ne4 Bb6 but here once again Rd5 had to be preferred. 20.g3? Missing a chance to get an advantage with quite logical [20.Nh4! Qc7 (20...Qxh4? 21.Nf6++-) 21.Nd6 and I don't see the way for Black to prevent the loss of an exchange.] 20...Nc5! From now on, black is just fine. 21.Nxc5 [The principal try would've been 21.Nd6 Nd7! 22.Nxb7 Rb8! 23.Nd6 (23.Nh4!? Rxb7 24.Ng6 Qe8 25.Nxf8 Nxf8 at first glance looks acceptable for Black .) 23...Rxf3 24.Qxf3 Nxe5 25.Qa3 Nxc4 (25...Bc7 26.Rd4 c5 27.Nc4 Nf3+ 28.Qxf3 cxd4 29.Re1 seems to be better for White.) 26.Nxc4 Qxa3 27.Nxa3 Bd4 28.b3 a5 and Black should hold this.] 21...Bxc5 22.Nh4 Rfe8 23.Ng6 Qf7 [23...Qg5!? would've limit White's options to 24.Rxc5 Qxg6 with equality, although it's hard to say what's better from the practical point of view.] 24.Qg4 Bb6 25.Rf4 Qd7 26.h4 Qd2


27.Rf6?! Brave, but objectively dubious sacrifice. [White could've tried 27.h5 , where 27...Qxb2?? (Correct would be just to wait with 27...Bd4 , where I don't see if White can improve his position, although it would still be unpleasant for Black.) 28.Rd1 would be a disaster for Black - 28...Kh7 (28...Rd5?


29.Qxe6+! that's a main motive of White's attack.; 28...Qxa2 29.Rxd8 Bxd8 30.Qf3!+-) 29.Rxd8 Rxd8 30.Nf8+ Kh8 31.Nxe6+-] 27...gxf6 28.exf6 Kf7 29.Nf4? A mistake, which could've lost the game in quite spectacular way. [Correct was unexpected 29.Nh8+! Kxf6 (obviously not 29...Rxh8 30.Qg7+ Ke8 31.Qe7#) 30.Qf3+ Ke7 (30...Kg7 31.Qf7+=) 31.Ng6+ Kd7 32.Rd1 Kc8 33.Rxd2 Rxd2 34.Qf7 Red8 35.Qxe6+ Kb8 36.Kg2 Rxf2+ 37.Kh3 Rfd2 with rather unclear position, where Black seem to have better prospects, but still both sides have fair chances to succeed.] 29...Kxf6 After this move Black can't escape the perpetual check, but it wasn't easy to find the following winning line: [29...Bxf2+!! 30.Kh1 (30.Rxf2 Qd1+–+) 30...Kxf6 31.Qg6+ Ke5 32.Qh5+ Ke4 33.Qg6+



33...Ke3!–+ 34.Ng2+ Kf3 35.Qh5+ Kxg3 36.Qe5+ Kh3!] 30.Qg6+ Ke5!? Brave try to play for a win. [30...Ke7 31.Qxe6+ Kf8 32.Qf6+ would lead to perpetual.] 31.Qh5+ Ke4 [Dubious would've been 31...Kd6 32.Rd1 Qxd1+ 33.Qxd1+ Kc7 34.Qh5 where queen+knight tandem seems to be very efficient.]


32.Kg2!! Brilliant move, which saves White half a point. 32...e5 [32...Rf8 was the only try to escape perpetual, although after 33.Qf3+ Ke5 34.Ng6+ Kd6 35.Nxf8 Qd5 36.Rd1 Bd4 37.Qxd5+ 


37...exd5 (37...Kxd5?? 38.Rxd4+ Kxd4 39.Nxe6++-) 38.Rxd4 Rxf8 39.Rg4 Black can hardly be better.] 33.Qf3+ Kf5 34.Qh5+ Ke4 35.Qf3+ Kf5 36.Qh5+ Ke4 ½

De, Filomeno Simone - Debashis, Das


In this complicated position Black has started the attack with an interesting piece sacrifice: 20...Ngf4 21.gxf4 exf4 22.Bc5? [Correct would've been 22.Bd4 Bh3 23.Ne5! Bxe5 24.Bxe5 where White's bishop all of a sudden plays defensive role, guarding g3: 24...Qg4+ 25.Ng3 fxg3 26.hxg3 Rae8 27.Bxc7 Qf3 28.Bf1 Bxf1 29.Rxf1 Re2 30.Qc3 Qg4!? , and Black still has some potential to attack.] 22...Bh3! 23.Ne1 [After 23.Bxd6 Qg4+ 24.Ng3 cxd6 White could've hope to escape with 25.Bh7+ Kh8 26.Bf5 Rxf5! 27.Qxf5


27...Nxg3! 28.Qxg4 Ne2+ 29.Kh1 Bxg4 30.Kg2 Nxc1 31.Rxc1 , and Black is "only" a pawn up.] 23...Qg4+ 24.Kh1


24...f3! Actually it doesn't even need a precise calculation - as long as all of your pieces are in attack - there must be something! 25.Bxd6 cxd6 26.Ng3 Rae8 I like this move as it bring the last remaining piece into attack, although it turns out Black already had enough forces for the decisive strike - [26...Nxg3+ 27.fxg3 (27.hxg3 Bg2+ 28.Kg1 Qh3 29.Bh7+ Kh8 with mate in one to follow.) 27...f2 28.Ng2 Qf3 29.Bf1 Rae8–+ (well, still the rook is needed)] 27.Kg1 Nf4! 28.Ra3 Bg2 [28...Re2 29.Bxe2 Nxe2+ 30.Qxe2 fxe2–+] 29.Nxg2 Nh3+ 30.Kf1 fxg2+ 31.Kxg2 Rxf2+ 32.Qxf2 Nxf2


Black has won enough material, albeit his attack is still not over yet. 33.Bf5 [33.Kxf2 Qf4+–+] 33...Qd4 34.Be6+ Kh8 35.Rf3 Nd1! 36.Kh3 Ne3 37.Rc7 Rxe6 38.Rf8+ Kh7 39.dxe6 Qg4# 0–1

Goryachkina, Aleksandra - Arabidze, Meri


Previous stage of the game saw a lot of tension already, but the main drama is still in front. White has some difficulties to convert his extra exchange as Black is quite stable, so zugzwang should be used as a method. 65.h5 Kh6 66.Re5 Kh7 67.Re6 Bd5 68.Rd6 Bc6 Black has nothing to do but to move here and back without blundering anything, and basically it's the worst in defending such a positions, as one loses concentration just so often... 69.h6 Bb5 70.Rf6 Bc6 71.Kf2 Bd5 72.Rf5 Bc6 


73.Rh5 Preparing to force Black into zugzwang, as now the bishop is the only piece which is moving. 73...Be8 Black is lucky to have this move, attacking the rook, otherwise White would've got the same position with his king being on e3, and that would've been a zugzwang. 74.Rh4 Bc6 75.Ke3 Bd5 76.Rh2 [76.Rh5 Bc6 77.Rh2 Bd5 78.Rh3 Bc6 79.Rh1 that is what an engine says in this position... Do you see any progress? Well, I don't!] 76...Bc6 77.Kd4


Looks like zugzwang, isn't it? So thought Black...77...f2? [Black could've played somewhat humiliating 77...Bd5 where the bishop can't be taken - 78.Kxd5? e3–+ , and, that being, I don't see how to make progress for White.] 78.Rxf2 Kxh6 79.Rg2! Cutting the king off, and normally that could've finish the game... But not such a dramatic one! 79...Kh5 80.Ke3 Bd5 81.Kf4 Bc6 82.Rg5+ Kh6 83.Rg3 Kh5 84.Kf5 Kh4 85.Re3 Bd5 86.Ke5 Bc6 87.Kf4 Kh5 88.Kf5 Kh4


And finally White played "the decisive" 89.Rxe4+?? [White should've proceed into a bit different pawn endgame, the one as shown in the following sample line - 89.Ra3 Bd5 90.Ke5 Bc6 91.Kf4 Bd5 92.Rg3! Bc6 93.Rg6 Kh5


94.Rxc6!, which is obviously winning for him. Perhaps Black's moves given in this line are not all forced, but I'm pretty sure Black can't avoid it.] 89...Bxe4+ 90.Kxe4 Kg4 91.Ke5 Kf3! 92.Kd6 Ke4 93.Kc7 Kd5 94.Kb6 [94.Kxb7 Kxc5 95.Kxa6 Kc6= I wonder if White missed this when went for the pawn's endgame.]


94...Kc4?? Incredibly careless move, missing the only possible white's idea... [94...Kd4! 95.c6 bxc6 96.Kxa6 c5 would lead to a draw of course...] 95.c6! Now it's all over, as Black finds his on king on the way of his passed pawn.... 95...bxc6 96.Kxa6 c5 97.Kb6 Kb4 98.a6 c4 99.a7 c3 100.a8Q Kb3 101.Qa1 1–0
