There are some international masters playing in ANCL and this season there was a shock in the first round:
TheButcher - FedorseevVladimir ANCL , 19.06.2010
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.h3 0-0 6.Nf3 e5 7.d5 a5 8.Bg5 Na6 9.g4 Nc5 10.Nd2 c6 11.Be2 Bd7 12.h4 Qb6 13.0-0
and not 13.Rb1? Nxg4 14.Bxg4 Nd3+ 15.Ke2 Nxf2 with advantage to black
13.Bxf6!?is not of course what white wants to play in this variation the black squares will soon be weak and without this bischop no attacks can succed.
13...Qxb2 14.Rc1 Qb6
very passive play 14...Rfc8!? is more thematic and another way is:14...cxd5 15.cxd5 (15.Bxf6? Bxf6 16.Nxd5 Bxh4 is good to black) 15...b5 with more or less equality ;in this kind of set up ,one thing is good to remember :to take on d5 is only good if ..b5 can follow.
15.Be3 with a draw offer
15...Qd8
again too passive 15...a4 preventing Na4 is better I think
16.Kg2 h5 17.gxh5 Nxh5 18.Bxh5 gxh5 19.Qxh5 Nd3 20.Rg1 !f5
20...Nxc1 may hold 21.Kh1 f6 22.Rxg7+ Kxg7 23.Bh6+ Kh8 24.Bxf8+ Kg8= but I understand that black avoided this line on the board
21.Kh2 Rf7
21...f4?? 22.Rxg7+ Kxg7 23.Rg1+ winning on spot.
22.Nf3 f4
22...Nxc1 23.Ng5 Qf6 24.Qh7+ Kf8 25.Qh5! Kg8 26.Bxc1 with a great advantage to white
23.Ng5 Re7??
23...Qf6 is the only move to stay alive 24.Rb1 fxe3 25.fxe3 but white is much better
24.Qh7+ Kf8 25.Rcd1+- fxe3 26.Rxd3 Bf6 27.Qh6+ Rg7 28.Rxe3 Kg8 29.Reg3 Qe7 30.Nh7
1-0
Good play from TheButcher .
