theory, but 10... e5 worked very well for Black in all the games played till
now.}) 11. cxd5 cxd5 12. e4 {Of course taking on e5 would no longer make any

all other moves, Black would go 15...Bg4 and simply equalize. [%eval 24,0]} (

We reached the typical setup in that kind of structures, where White is up a
pawn that he cannot really hold. The only question is always: can White force
Black to capture the pawn back in poor conditions? [%eval 72,0]} 19. Nf5 {
Of course after taking the bishop pair, White has a very (very) slight
advantage, but it doesn't seem enough at all. It seems to me that after 19.Nf3
White would have decent chances to get some advantage, though Anand had been
playing very fast until 18...h6, which should mean he has some precise idea
against 19.Nf3. [%eval 40,0]} (19. Nf3 $5 Nxd5 ({
Of course it would be possible to delay ...Nxd5, but after a move like} 19...

clear to me that Black should have some problems, though maybe solvable.}) 20.

exactly equalize, e.g.} Qb6 (21... Nc3 $2 22. Bh7+ (22. Nxc6 Nxb1 23. Nxd8 Nxd2

22. Nxc6 bxc6 23. Bh7+ Kh8 24. Bd3 $14 {Most probably Anand had some idea
which I just miss! I'm also not sure how easy is the calculation of 21...Nxc3
over the board.}) 19... Bxf5 20. Bxf5  Rc5 21. Rfe1  (21. Rc1 $5 {is an interesting option,
but whatever Black plays he is very close to equality. At least much closer
than in the 19.Nf3 line is Black doesn't have a clear way to exchange some
pieces.}) 21... Rxd5  22. Bc3Rxe1+

never advance so easily due to some problems with the 2nd file!}) 33... Ne7 34.
Be4 Kg7 {Though equal score, the impression after four games is that Anand is
drawing with Black much more easily than Gelfand is. This means Gelfand is a
little bit under pressure, and that his team will have to find more resources
with White. But Gelfand's play is anyway very dynamic, and it is clear that
the Israeli will be ready to punish any mistake from his opponent. Let's not
forget that Gelfand had more problems with Black, but also played riskier
openings: and the result 0-1 also exists in chess!} 1/2-1/2
