1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. g3 {I think we get Anand's match strategy now:
play like Kramnik and remind Topalov of his favourite person.} dxc4 5. Bg2 Bb4+

Qd5 9. Qxd5 exd5 $11 {[%emt 0:33:02] Browne-Smyslov Las Palmas}) 8. Qxd2 ({The
Catalan has been all the rage since Kramnik started to play it. For the latest
theory it is best to consult the brilliant book by Boris Avrukh.  I refer to
it all the time.} 8. Nbxd2 b5 9. a4 c6 10. b3 cxb3 11. Nxb3 O-O $13 {White has
some play but not enough for advantage - Avrukh}) 8... c6 9. a4 (9. Ne5 b5 10.

Kramnik-Topalov game 1 Elista 2006, but Avrukh suggests Black can improve})

new but typical Catalan position where White has full compensation. Black has
to watch out for d4-d5 opening the Catalan bishop and undermining his
queenside pawn chain} Be8 (14... Qe7 15. Nxd7 Qxd7 16. d5 exd5 17. exd5 cxd5

Ng4 (16. dxc6 $5 Qxe5 17. axb5 {looks promising but Black can sacrifice back
and is only a bit worse}) 16... Qc5 17. Ne3 {#The perfect square supporting d5.
Topalov's problem is capturing on d5 opens the Bg2 but leaving it allows dxc6}

a nice edge}) 19. Naxc4 Bxc6 20. Rac1 {#White looks more comfortable here but
nothing could prepare us for what follows. Topalov's sense of danger deserted
him} h6 $6 {Stops Qg5 in some lines and challenges Anand to do something
constructive which he declines to do and does something very destructive
instead! Getting the queen near the kingside made sense} (20... Qe7 21. Nxa5 (

it's critical. The black pieces have deserted the king.#} Rad8 $2 (22... Nc5 {

attacking plan.}) 23. Nxh6+ gxh6 24. Qxh6 f6 25. e5 {#Anand reached to play
this move, the brought his hand back then played it a minute later. Nerves ?
not surprising. It took him 10 minutes in total but now it's game over} Bxg2 (
