A Good Bad Bishop

Caruana becomes sole leader of the final GP stage in Khanty-Mansiysk

Today is the first rest day in the decisive stage of the FIDE Grand Prix cycle. Yesterday was round four, which produced a sole leader in the shape of Fabiano Caruana, the rating favourite and only 2800-player in the event, who scored his second successive win: one day earlier he beat Tomashevsky, and yesterday he convincingly defeated Maxime Vachier-Lagrave as Black.

In reply to 1.d4 Caruana chose the Ragozin Defence, which somewhat surprised his opponent. However, play soon went into lines typical of the Queen's Gambit, which the Frenchman had expected anyway. 

VACHIER-LAGRAVE - CARUANA

This position can arise in one of the sidelines of the Cambridge Springs Defence, with the sole difference that the Rc1 would normally be on a1. The extra tempo here makes no difference to the assessment, but does introduce some interesting nuances.
14.Ne5 Ng4! In the "original form", this knight jump isn't good due to 14...Bxe5 15.dxe5 Ng4, but here this leads to unpleasantness: 16.Bf5! Nxe5 (Relatively best is 16...Qc7!, although after 17.Bxg4 Bxg4 18.f4 Black has problems) 17.Bxc8 Rxc8 18.Qf5 Nd7 19.Nxd5.
15.Nf3 (After 15.Nxg4 Bxg4 the position is equal) 15...Nf6 16.h3. To set up the Pillsbury Bind (Ne5 and f2-f4), White needs to spend a tempo on this move of the RP. However, the decision to avoid a repetition is reasonable.
16...O-O (Here Fabiano thought for a long time over the immediate 16...a6!? and 17...с5) 17.Ne5 a6 18.f4. Caruana's suggestion of the prophylactic 18.Na4!? is interesting- this was the reason Black thought so long about the "obvious" castling. However, Vachier, by his own admission, was not afraid of c6-c5.
18...c5 19.g4! cxd4 20.exd4 Be6. And here, barely out of the opening, the French GM made a serious mistake.  

21.Qb3? Since White's play involves an attack on the king, here the queen does absolutely nothing. After the correct 21.Qf2 (or 21.Kh1!? - Caruana) White's chances are slightly better, eg. 21...Rac8 22.a3!, and 22...Bxa3 is dangerous because of 23.g5!
21...b5 22.f5 Qb6! This intermediate move, which Vachier had missed, is stronger than 22...Bc8? 23.Nc6! and 24.Nxd5, with advantage.
23.Nf3 Bc8 24.Kg2. Only White, whose king is exposed, can have problems here. An interesting line is that pointed out by Maxime at the press conference: 24.a4 b4 25.Nxd5 Nxd5 26.Qxd5 Bb7 27.a5! Bxd5 28.axb6 Rfb8 29.Bc4 with rough equality, although this variation is far from forced. 
24...Bb7 (The bishop may look completely dead here, but that is a mistaken impression.) 25.Na4 Qa7 26.Nc5 Rac8.

27.a4? Upset by the previous course of the game, Vachier makes a further mistake, and this time decisive. At the press conference, the players came to the conclusion that 27.Qa3 Ne4 28.b4 Qb8! (if 29.Nd7, then 29...Bxb4!) is also bad, and that White had to play 27.Nxb7 Qxb7 and then, for example, 28.a4 b4 29.a5, although here too, Black's position is clearly the more pleasant.
27...Bxc5 28.dxc5 d4! The bishop, which only a few moments ago looked "bad", suddenly becomes a hero. Pawns do not matter, since with such a king, White will not survive. "I was still hoping to set a few traps, but the problem is that Black has more than one way to win," – Vachier-Lagrave.
29.axb5 axb5 30.Qxb5 Bc6! 31.Qb6 Qd7. Here the curtain could be pulled down. With logical moves, Caruana carries his attack to its logical conclusion.
32.Kg1 Rfe8 33.Rce1 Rxe1 34.Nxe1 Re8 35.Ng2 Nd5 36.Qb3 Ne3 37.Nxe3 dxe3 38.Qc4 Qc7 39.Qf4 Qxf4 40.Rxf4 e2 41.Bxe2 Rxe2 42.Rb4 Rg2+ 43.Kf1 Rc2 0-1 (Notes by GM Andrey Deviatkin).

The other games of the fourth round were all drawn, mostly without great interest. The exception was the meeting between the two Russians, Tomashevsky and Jakovenko. With White, Evgeny was pressing the whole time, but could not convert his advantage into a full point.

TOMASHEVSKY - JAKOVENKO

41.a5? A typical case of a mistake on the move after the time-control. Tomashevsky saw the correct move 41.Qb4 with the idea of 41...h5 (the computer recommends going into a difficult rook ending with 41...Qf8) 42.Rb8! Rxa4 43.Qb7 Qf6 44.Qc8 Kh6 45.Qf8+ Qg7 46.Qe7 with irresistible threats, but in the end refrained from the queen move because of 41...Qf6 42.Rb8 Kh6. Interestingly, at the press conference the players spent some time exchanging their analysis at this point, looking at complicated lines, but missing the simple two-move win 43.Qf8+ Kh5 44.Rb7.
UPD. We have been too harsh on the GMs. The win is short indeed, but the continuation of the line is not obvious: 44...Ra2 45.Rxf7! (the only move) 45...Rxf2+ 46.Kh3! Qxf7 47.g4#
41...Ra2 42.Qc3 h5 (Now White cannot strengthen his position because of the permanent threat ...Qf6) 43.Rb6 Ra4 44.Rb5. 1/2

After four round, Caruana has 3 points, Dominguez and Svidler 2.5, Grischuk, Tomashevsky, Nakamura, Karjakin, and Gelfand 2. The fifth round is tomorrow, 19 May. Taking into account today's results, the current overall GP standings are as follows:
