{known as the Lasker variation, has been gaining steady popularity.}) 8. g4 $5
{White has tried everything under the sun in this position, but g4 is a very
new idea! It has scored well so far, and Black players of this variation will
have to figure out how to diffuse it.} Nxg4 {Accepting the pawn on g4 loses
the pawn on d5. The position takes a sharp turn.} (8... c5 $5) (8... Nbd7 $5)
9. Bxe7 Qxe7 10. cxd5 exd5 11. Nxd5 Qd6 12. Nc3 {White's central structure is
good, and if he can keep it intact he could evne claim some sort of advantage
one he plays h3 and finshes his kingside development. However Black should
have good piece play and there must be some way of developing.} c5 {Natural}
13. Rg1 Nf6 14. Bg2 Bg4 15. Qd2 Nbd7 16. Ne5 Nxe5 {This exchange sacrifice is
rather obvious and it should give Leko at least enough compensation.} (16...

pieces.}) 17. dxe5 Qxe5 18. Bxa8 Rxa8 19. Rg3 {For the exchange Black has good
piece play, a pawn and White has some difficulties finishing his development.}
Ne4 $6 (19... Qf5 $1 {This patient move binds White by installing a bishop on
f3. After that it is not so easy to find a move for Grischuk.}) 20. f4 $1 {
Perhaps Leko missed or underestimated this strong move. By forcing the queen
trade White loses a pawn, but he gains enough time to mount a
counter-initiative.} (20. Nxe4 Qxe4 $17) 20... Nxd2 21. fxe5 Nf3+ 22. Kf2 Nxe5
