A Good Start

The start of the super-tournament Wijk an Zee could not have been better! Three games in the Master section were decisive and none of teh Challengers games ended in a draw! Probably the most exciting battle of this first round was the following one:

Qe2 {[%csl Yc7] Diagram [#] Funnily, similar position without the c7 pawn will
arise in plenty of lines- the QGA, Nimtzo-Indian and Panov attack in the Caro

development and attacking possibilities.}) 13. Bd3 Nfd5 {Just like in the
lines where Black plays against the isolated pawns he is happy to trade as
many pieces as possible.} 14. Bg3 Bd7 $146 {Diagram [#]} ({A novelty in

counter-play on the queenside. In the future he wants to swing his rook along
the fourth rank for kingside attack with Rc1-c4-(g4) and he is happy that

the battery.} 23. Bb1 Kh8 {Not a bad move but there was a better one! After
great defense Eljanov starts to play over cautiously and this will finally
lead him to real problem. The king stepped away from the check on f6 and this
is useful, but it was far more useful to regroup with} (23... Rxd1+ 24. Rxd1
