specialist with Black and has quite some experience against it with White, too.
For this game he unexpectedly chose the Catalan setup which he had never
employed in this position. During his home preparation he might have noticed
that his young and talented opponent (who in the meanwhile had become
Romania's youngest grandmaster ever) has a marked defensive style and enjoys
playing somewhat cramped but solid positions. Dreev must have hoped that the
irrational positions frequently arising from the Catalan gambits would put his
opponent off balance. Up to a certain point his strategy proved right.} dxc4 {.

there are cases like this when I cannot access my mental storage completely. I

path. White's main idea is keeping the bishop on f1 for a while in order to
meet ...dxc4 with e2-e4. Depending on Black's reaction, White could play
either e2-e4 or c4-c5. I was later surprised to see that among the not few

black bishop pair should not be underestimated.} (11. e4 dxc4 $1) 11... Nd7 12.

position is extremely difficult to evaluate. White has a lead in development,
more space and seems to enjoy a slight edge, but Black on the other hand has
the two bishops, an outpost on d5 and easy play, as he just needs to

It´s unlcear if this knight exchange is a good idea. After all the knight on
e4 was important for preventing any c5 breaks. And after its exchange White
remains with the knight on f3 and the g2-bishop, two pieces that seem quite
passive. Furthermore in general the side with more space should try to prevent
exchanges of minor pieces.} (30. Qe2 $5) (30. Qc4 $5) 30... Nxc3 31. Rxc3 Bc7
