Biel 08: Navara, Wojtaszek lead

by Alejandro Ramirez
7/28/2015 – The super tournament in Biel is coming to a close, but the fighting continues in strong fashion. Two decisive games were seen today, and the one draw could easily have been a win for Eljanov in his duel against Wojtaszek. The Pole survived and shares the lead against Navara, who simply wiped Rapport off the board. MVL put the positional pressure on Adams, who eventually cracked.

Round 8 report by Rustam Kasimdzhanov

Rapport, Richard 0-1 Navara, David
This is a hard game to explain. Rapport's decisions were all around strange, which is arguably normal for the Hungarian, but some of them were simply bad:

A big day for Navara, not only did he win, but joined Wojtaszek in the lead

It's not clear to me why White releases the pressure on the queenside and allows Black to take on b5 with the c-pawn, liberating the bishop on b7. cxb5 13.Ng3 White is prepared against e5. Black could first play 13...g6 to defend f5, but Navara evaluates that as unnecessary. e5 13...g6 14.Bd2 14.Bb1 14.Nf5 Bb8 14...Bc7!? 15.dxe5 Nxe5 and Black has a more comfortable position. 14...Re8 15.Ba2 White targets the soft f7 pawn. However with Black's superior development (compare the power of Black's two bishops and White's two bishops, not just the one on a2), it is clear that Black is to be prefered. h6?! This move looks natural, to stop Ng5, but it was perhaps a good time to bring some other pieces into the game. 15...exd4 16.Nxd4 Ne5 and the knight lands on e5 immediately, unlike the long route it takes in the game to achieve some activity. 16.Bd2 Bc7 17.Nh4 Nf8 18.Nhf5 Ne6 19.dxe5 19.Bc3! 19...Bxe5 20.f4? A very ambitious pawn sacrifice (?) but it is completely unclear what Rapport actually gets for his pawn. Bxb2 20...Bc7 21.Bc3± is not even an option. 21.Rb1 Ba3 22.Bc3 Qxd1 23.Rbxd1 There is plenty of pressure on the kingside, but Navara has a good way of beating back the attack. Ne4 24.Bxg7? 24.Nxe4 Bxe4 25.Nd6 Bxd6 26.Rxd6 White is just down a pawn, but at least he has some fighting chance. 24...Nxg3 25.hxg3 Be4 White isn't losing a piece, but he is losing the game. 26.Bb2 Bxb2 27.Nd6 Bc6 28.f5 Ng5 29.Nxe8 Bxe8 The smoke has basically cleared. Black has a completely won position: two pieces for a rook with two passed pawns on the queenside that are very dangerous. Navara mops up nicely. 30.Rd6 Kh7 31.f6 Be5 32.Rd5 Bxg3 33.Rfd1 Kg6 34.Rf1 Kh7 35.Rfd1 Bc7 36.Bb1+ Kg8 37.Kf2 Nh7 38.Rc5 Bb6 39.Rcd5 Nxf6 40.Rd6 Ng4+ 0–1

Rapport,R2671Navara,D27240–12015D4748th Biel GM 20158

Rapport severely underestimated how much activity Black got from the pawn trades

Vachier-Lagrave, Maxime 1-0 Adams, Michael
MVL put pressure from the beginning; Adams eventually cracked.

MVL played it calm and slow. His pair of bishops eventually caused his opponent to falter.

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.c3 d5 9.exd5 Nxd5 10.Nxe5 Nxe5 11.Rxe5 c6 12.d3 Bd6 13.Re1 Bf5 14.Qf3 Qh4 15.g3 Qh3 16.Be3 Bxd3 17.Nd2 Qf5 18.Bd4 Rae8 Adams has played the Marshall his entire life. This Rae8 move is a slight divergence from Rfe8, which was the game between Caruana-Aronian in Zurich last year. Caruana annotated that game in detail, you can find that in the Megabase 2015. 18...Rfe8 19.a4 19.Kg2 19.a4 would have been the "equivalent" of the other line. It probably would just transpose. 19...h6 20.a4 Qxf3+ 21.Kxf3 Re6 22.axb5 axb5 The position has a symmetrical pawn structure, but White is slightly better. He has control over the a-file, Black has some problems with the pressure generated by the b3 bishop, and he doesn't have any clear targets. 23.Kg2 Rfe8 24.Rxe6 Rxe6 25.c4!? Semewhat counterintuitive, but the point is that the activity given to the White knight with this break is worth the trade of a couple of pawns. bxc4 26.Nxc4 Be4+?! 26...Bc7! 27.Ne3!? Be5! and Black is close to equalizing. 27...Nxe3+ 28.Bxe3 is slightly annoying, with Ra7 coming next. 27.f3 Bd3 28.Nxd6 Rxd6 29.Kf2 The pair of bishops is a nice advantage to have. Material is reduced, yes, but White is clearly better here. Black's pieces cannot compete with the power of that bishop on d4. Rd7 30.Ra3 Nc7 31.Be3 Nd5 32.Bc5 f6 33.Ba4 Bb5 34.Bc2 Nc7 35.Bg6?! Na6 35...Rd2+ was a nice time to get some activity. For example: 36.Ke1 36.Ke3 Re2+ 37.Kd4 Re5 does not look right at all. 36...Re2+ 37.Kd1 Na6 but White is still a bit better. 36.Re3 Rd8 37.Be7 Rc8 37...Rd2+ 38.Ke1 Rxh2 39.Bc5 doesn't get Black mated, but it is still unpleasant. Rh1+ 40.Kf2 Rh2+ 41.Kg1 Re2 42.Rxe2 Bxe2 43.Bd6 and even though Black is up a pawn, he is completely paralyzed. He cannot even take on f3 here because Bd3 traps the knight! That being said, Black might have had no choice but to go for this line. 38.b4 c5? A blunder. 38...Nc7 39.Bd6 Nd5 40.Ra3± 39.Bf5! Rc6 39...Rc7 40.Bd6 Rc6 41.Re8+ Kf7 42.Rf8# is not an option. 40.Bd7! cxb4 41.Bxc6 Bxc6 42.Re6 Black will lose the b4 pawn next move and the resulting endgame is lost. Arguably Black could keep on playing, but MVL would definitely convert this. 1–0

Vachier Lagrave,M2731Adams,M27401–02015C8948th Biel GM 20158

Adams probably knew the Caruana-Aronian game, but his improvement was not too impressive

Eljanov, Pavel ½-½ Wojtaszek, Radoslaw
Eljanov was torturing Wojtaszek the entire game. He was arguably close to winning at several moments of the game, but he was unable to finish Wojtaszek off. Eventually the game went into a rook and knight vs. rook endgame which Wojtaszek was able to hold.

Eljanov moves further away from Rapport
