The start of an interesting attack

19. N5e4 Qa4 20. Kb1 Bh8 21. f5?! exf5 22. gxf5 gxf5 23. Nxf5 Rxe4!!

A bolt from the blue!

24. Bxe4 Nc3+!! 25. Bxc3

25. bxc3 Bxe4 and black threatens tyo regain the piece by ...Rf8 as well as ...Qxc2+ and/or ...Nc4

25... bxc3!!

Now black threatens a quick mate with 26...Qb4 27.b3 Qa3 and 28...Qb2 mate

26. Rd3 Bxe4 27. Rxc3 Rf8 28. Qh4!

A nice try

28... Qb5!

28... Bxf5? 29. Rxf5! Rxf5 30. Qd8+

28... Rxf5?? 29. Qd8+!

29. Rf4 Bxf5!

29... Bxf5 and now 30. Rxf5? doesn't work because of 30... Qf1+!!

0-1

White's been successful on the queenside, but the price is that his kingside defence is a little thin

26. Qe1 Bf6 27. Nb6 Nxh2!!

An amazing sacrifice from left field

28. Bxf5

The immediate point of the sacrifice seems to be 28. Kxh2? Bh4 29. Qe5 Bg3+ 30. Kg1 Qh4 with a mating attack

28... Nxf1! 29. Nxc8 Rxc8 30. Bxe6 Nxd2! 31. Bxc8 Nxb1! 32. Qxe7

Another beautiful point of the combination - perhaps overlooked by Navara, is that after 32. Qxb1 Qe3+ seems to give a winning attack, eg(32... Qc7! 33. d5 should also win, given the white king's vulnerability) 33. Kh1? (33. Kf1 Bh4!) (or 33. Kh2 Qxf4+ 34. Kg1 Qe3+ 35. Kh2 Bh4) 33... Qh3+!

32... Bxe7 33. Nc4?!

c4 seems to keep white in the game

Closing the centre gives both sides a free hand on the flanks

11. Re1 Bb7 12. h4 Qc7 13. Nbd2 a6 14. Nf1 b5 15. b3 bxc4 16. bxc4 a5 17. Bf4 a4 18. a3 Na5 19. Rab1 Rb8 20. N3d2 Bxg2 21. Kxg2 O-O

Black castles into it, but otherwise it's hard to get the Rh8 into play

22. Nh2 Rb7 23. Ng4 Qc6+ 24. Ne4 Rfb8 25. Rxb7 Rxb7?!

...Qxb7 would allow black ...Qb2 etc

26. Qf3 Rb3 27. Bd2! Qa6 28. Nh6+!!

Fairly standard in these King's Indian Attack positions, but always nice to watch

28... gxh6 29. Qg4+ Kh8

29... Kf8 30. Bxh6+ Ke8 31. Qg8+ Bf8 32. Bxf8 Nxf8 33. Nd6+

30. Bxh6 Bf8 31. Bxf8

31. Nd6 Qc6+ 32. Kh2 Nxe5 33. Rxe5

31. Ng5!? is very flashy but loses to 31... Qb7+ 32. Kh2 Nxe5 33. Rxe5 Bxh6

31... Nxf8 32. Nf6 Ng6 33. Qh5!

33. h5!? Ne7 34. Ne8 Nf5 doesn't seem to work

33... Qc6+! 34. Kh2?!

34. Re4! looks more active

34... Kg7

34... Nf8? 35. Qxf7

35. Qxh7+ Kf8 36. h5 Rb2!

This counterattack illustrates the disadvantages of Kh2?! earlier

37. Ne4?!

37. hxg6 Rxf2+ 38. Kh3 Qg2+ 39. Kh4! Qh2+ 40. Kg4 Qxh7 41. gxh7 Kg7 42. Rh1 Kh8 43. Rh5! with the idea of Rh5-g5-g8 winning

37... Ne7 38. h6?

38. Qh8+! Ng8 39. h6 looks winning

38... Ng6! 39. Qg7+ Ke7 40. h7?

40. Qf6+! seems stronger eg 40... Kf8?? (seems stronger eg 40... Kd7 41. Qxf7+ Ne7 42. h7 Rb8 43. Nf6+) 41. Qd8+ Qe8 42. Qxa5

40... Qe8 41. Qf6+ Kd7 42. Nd6

42. Nxc5+ looks good too

42... Qf8 43. Nxf7 Nh8! 44. Qxh8 Rxf2+ 45. Kg1 Qxf7 46. Qa8??

46. Qg8 is met by 46... Qf3! with mate coming
