London: Carlsen and Aronian maintain lead at the half way stage

The 7th round of the Candidates tournament taking place in London turned out to be much calmer than the previous two rounds. Nevertheless, there was a chance of putting the competition upside down as Teimour Radjabov had an opportunity to defeat one of the leaders Norwegian Magnus Carlsen.  

CARLSEN - RADJABOV

The opening stage (Rossolimo variation) didn't went smoothly for White and Black tried to grab initiative. From a human point of view Black already has initiative, but here Magnus could keep balance by an accurate 21.Qg4! (or 21.Qh3). Important was occupying the diagonal the black queen is trying to use for reaching white king. 21...f3 22.g3 Ng2 23.Red1 Rf6 24.Nc3 Rdf8 25.Kh1 and strangely enough Black has nothing better than repetition 25...Rg6 26.Qh3 Rh6.
21.Qe4? f3 22.g3 Ng2 White queen took the most uncomfortable position, so giving the exchange is essential in order to hold the position.
23.Nc3

23...Qe6?! Teimour was tempted by a wish of playing for the checkmate, perhaps taking the material was more accurate: 23...Nxe1 24.Qxe1 Bc7! - the bishop plans to move on a5 and 25.d4 gives nothing because of 25...Qe8.
24.Re3! The only move. 24...Nxe3 25.fxe3 f2+?! another miscalculation. White would have harder times if Teimour has played 25...Bе7 or even stronger 25...Bc7 26.Bxc5 Bd6.
26.Rxf2 Rxf2 27.Kxf2 Rf8+ 28.Ke2

28...Qh3 In a time toruble Azerbaijani missed the last chances of playing for a win: 28...Qf6 with an idea of 29.Qg2 e4 30.Nxe4 Qa1 31.Nd2 Rf6. After Radjabov's choice White has no problem in holding the game.
29.Qh1 Be7 30.Ne4 Qg4+ 31.Kd2 Qh3 32.Ke2 h5 33.Bb2 Qg4+ 34.Kd2 Qh3 35.Ke2 Qg4+ 36.Kd2 Qh3 37.Ke2 1/2

Boris Abramovich Gelfand could also become the hero of the day.

GELFAND - KRAMNIK

Kramnik has just blundered 18...Ne8? and if Gelfand would find 19.Neg5! it's most likely that the former world champion's string of draws would be ruined. Any variation here would lead to White's advantage: for example, 19...h6 20.Bg6! fxg6 21.Qxe6+ Kh8 22.Nf7+ Kh7 23.Nh4.

Gelfand failed finding the strongest move: 19.Ned2? after which the equality led the game to the draw.
