Someone had better beat Viktor Bologan soon, or maybe just wake him up! The Moldovan GM is cruising through the first supertournament of his life as if he usually eats 2700s for breakfast. He disposed of the world #3 on Saturday and on Sunday it was time for #4, Peter Leko.
46 moves later Bologan became had extended his lead in Dortmund to a full point ahead of world champion Vladimir Kramnik. Leko got a solid plus against Bolo's Caro-Kann Defense but then went astray trying to convert his advantage after sacrificing a pawn. Bologan played good defense and grabbed the first opportunity to steal the initiative.
Standings after round four
You'll notice in this pre-event publicity photo from the official site, Bologan (back-left) is the one with the biggest smile. Was it because he was just happy to be there or because he knew something the other guys didn't? Maybe it's his lucky lime-green jacket and brown shirt combination. (It'll be all the rage at your next tournament.) Leko is clearly being punished for changing his wardrobe, which is usually very colorful.
Are you ready for some new math? After four rounds Arkady Naiditsch has more wins than Peter Leko and Vishy Anand combined. He defeated fellow teen Teimour Radjabov (therefore validating one of our little pre-event predictions) when the Azerbaijani aggressively sacrificed a piece, and then a rook, for a mass of central pawns but couldn't keep up the attack.
Some
of Naiditsch's comments to the press on his game: "It looked more like
Rajdabov's nature to sacrifice a knight, take the center, but I was prepared."
... "From outside my position might have looked suspect, with king in the
center, pawns rolling down etc., but White was always holding on." ...
"With accurate defense, he was getting it tough and sacrificed his rook
more in a last ditch effort, but by then it was gone." ... "Despite
the menacing pawns in the center, my rook up position was assuring and I was
confident of victory."
Anand used the white pieces to take a day off to recover from his two consecutive losses. Against Kramnik he repeated a queen sacrifice line of the (guess) Sveshnikov introduced by Topalov against Leko in 2000. That game went for 87 moves before the draw was agreed, this one only lasted 25 with nary a new move to its (dis)credit.
A few years ago it would have been strange to hear about Peter Leko pressing too hard for a win and losing. In the last two years his style has been reinvented and despite his three draws to start this event Leko has been playing hard. Against Bologan he played well enough to win but at key moments he missed promising continuations that would have given him excellent winning chances.
