Highlights from Round 10

Li Tian played the white side of a Scotch Opening very passively. Then he got into a lost double rook ending. The following position was reached -

Yeoh Li Tian - MariusAbramciuc
White has just played 42. Rc2 attacking the black c-pawn. After 42...Rb4 and ...b5 the black pawns are unstoppable. However

42...Rc5??? 43. Rd7+ ( must be kicking himself, the king has no escape squares)  Rd5 44. Rd2+ Kc3 45. R2xd5 winning a whole rook.

Oleg Gorbanovsky - Yeap Eng Chiam

 White just played 48 Kg4. Eng Chiam grabs the chance to exchange rooks.

48....Rd6! 49. Kf5 Rxg6 50. hxg6 Ke7 51. Ke5 Bg7+ 52. Kd5 a5!

This looks like a terrible move but Eng Chiam has a clever idea in mind.
53. Kc6 Bd4!

The point is that the b-pawn is poisoned e.g 54. Kxb6?? c4+ and it is black who wins. Without the possibility of winning the b-pawn, white has no chance and the game was drawn after some moves.

Roshan - Egor Procop
White has just played 17. Nd6 . Now black should give the exchange with 17...Bxe5 18. Nxe8 Be6! (the knight is not going anywhere). with two pawns and good attacking chances on the white king. Instead

17...Rf8? 18. Bc4 Bxe5 19. Nxf7 

Black thought for a long time here perhaps realizing he is lost!  19...Bd4+ 20. Qxd4 cxd4 21. Nxd8 Rxd8 22. Bg5 and surprisingly black must lose material. e.g 22...Rd6 23. Bf4 or 22. Rd7 Bh6! and the mate on f8 cannot be met.
19...Bxh2+ 20. Kxh2 Qh4+ 21. Kg1 Qxc4 22. Nh6+ Kg7 23. Rxf8 Kxf8 24. Qf3+ 

The black king must run for his life. 24... Bf5 25. Nxf5 gxf5 26. Qxf5+ Kg7 27. Qg5+ Kf7 28. Bd2! bringing out the rook 28...Rg8 29. Qh5+ and the black king will suffer with all white pieces trained on him.

Ke7 25. Bg5+ Kd7 

25... Kd6 26. Nf7+ Kc7 27. Bd8+ followed by a knight fork on king and queen.

26. Rd1 Kc6 27. Nf7 

The simple 27. b3 wins a piece straight away.

Kb6 28. a5+! Ka7 29. Rxd5 Be6 30. Rxc5 Qb4 31. Qe3 Ka8 32. Nd8 Bf5 33. Rc7 h6 34. Nc6 1-0
