Kongsee Uaychai- Lim Zhuo Ren : 0-1 !

Kongsee Uaychai (2273)- Lim Zhuo Ren (2120)
Istanbul Olympiad, Round 11, 9.8.2012

Analyzed by Centaur (Hairulov + Ryba 4)

1.e4 c5 2.Nf3 d6 3.c3 

Alapin ( pronounce: ah-LAH-peen) variation though my MAKSAK's teamate like to call it "Ayah  Pin" variation?! 3...Nf6 the best continuition because it prevent white to estabalish a big center for e.g. 4.d4? Nxe4

4.Be2 Nc6 of course taking the pawn with 4...Nxe4?? will lead into a booby trap after 5.Qa4+ winning the knight on e4.

5.d3 white have to protect the e4  because the Qa4+ check doesn't work anymore 5...g6 6. 0-0 Bg7 7.Nbd2 White can set a trap with 7.d4  and if 7...Nxe4?? then black lose a piece after 8.d5! Ne5 9.Qa4+ and again, the knight on e4 will lose 7...0-0 8.Re1 Qc7 Rybka opening book suggest 8...b6 9.Bf1 d5  10.h3 10.e5 straight away will be answer with a strong 10...Ng4! so white prevent it first. 10...e5 if not white will play it himself. 11.Nb3 b6 12.Bg5 d4 13.Rc1 Bb7 14.Qd2 Rac8 15.cxd4 cxd4 16.Nh2 Ne8 17.Be2 f6 18.Bh6 Bxh6

Black does not mind exchanging his dragon bishop because the center is lock so his bishop does not have much prospect. 19.Qxh6 Qg7 20.Qd2 Nd6 21.f4 a5 22.fxe5 fxe5 23.Bg4 Rce8 24.a4?!  

now black have a strong post on b4 for his knight and followed by Ba6 later will put pressure on white's d3 pawn.

24...Nb4 25.Rf1 Rxf1+ 26.Rxf1 Bc6 27.Ra1 Qf7 White a4 pawn and Knight on b3 is a clear target. 28.Bd1

White have to defend passively. His rook on a1 is passively defending the a pawn.

28...Rf8 Now Black control the f - file 29.Nc1 Threatening 29.Bb3 of course 29...Kh8 30.Bb3 Qf6 31.Nf3 Kg7 32.Kh2 h6 33.Kg1 Now it is clear that white have no clear plan to proceed so he just wait and see. 33...Bd7 Another interesting plan is to re-position his d6 knight with 33...Nb7 and 33...Nc5

34.Kh2 Nb7 35.Ne2?

This will cost white a pawn. Correct is 35.Bc4 Nc5 36.b3 35...Nc5 36.Bc4 Bxa4

Black win a pawn.

37.Rc1? Qd6 threatening 38...b5 next to win the d3 pawn! 38.Ng3 Bc6 38...b5 as i mention  is also strong.


39.Ra1 has to be played. 39...b5 40.Bd5 Bxd5 41.exd5 Nb3 Black will and material and he has  a winning position. 42.Ne4 Qb6 43.Qd1 Nxc1 44.Qxc1 Nxd5 45.Nf3 Nf6 46.Nxf6 46.Nxe5? Nxe4 47.dxe4 Qd6 and white will lose his knight. 46...Rxf6 47.Qc8 Qd6 48.Kh1 Qc6 49.Qb8 

49...Rxf3! Lim Zhuo Ren end his brilliant campaign in Istan bul with style. 50.gxf3 Qxf3+ 51.Kh2 Qe2+ 52.Kg1 Qxd3 53.Qxe5+ Kf7 54.Qd5+ Kf6 55.Qd6+ Kf5 56.Qf8+ Ke4 57.Qe7+ Kf3 58.Qf6+ Ke2 59.Qf1+ Kd2 0-1  White resign

Lim Zhuo Ren won and can some one confirm whether he got his IM norm or not with this victory?
