BEWARE THE CHINESE KNIGHTS!

(part I)

ch-CHN Xinghua  2016.4.17  gm Xu, Jun–Xu, Yinglun (2523). Position after 19 moves of play. Clearly White stands better; his better pawn structure and more active pieces more than offset Black’s Bishop pair. Besides, Black’s King is a bit open.

WHITE TO PLAY AND WIN!

ch-CHN(w) Xinghua  2016.4.18  wgmTan, Zhongyi (2518) –wgm Zhang, Xiaowen (2340). Position after Black’s 25th move (25…Ba6). White has an obvious positional advantage and was threatening Rd7, so rather than defend passively, Black set a little trap: if now 26.Rd7(?) BxB! turns the tables on White because of back-rank problems: for example if 27.h3!? (clearly taking the Queen gets mated) 27…Ra1+ 28.Kh2 Rh1+!!

But it is always a risky business to base one’s defence entirely on tactics (tricks)…for there is usually always a move that one misses in one’s calculation. (Hint: it is not forced to play the Rook to the 7th rank)

WHITE TO PLAY AND CRUSH!

SOLUTIONS

(Note: my apologies if today’s training is more difficult than usual)

ch-CHN Xinghua  2016.4.17 Xu, Jun–Xu, Yinglun: 20.Rd6! Bf7 (No better is 20…Bd7 21.Nh4! g5?! But what else against White’s threats?  22.Nxf6 Bxf6 23.Nf5+! Kf7 24.Bh5+ etc) 21.Nh2! Threatening the immediate Ng4 winning a piece.  Black resigns.  A bit premature, but correct.  If 21…Rf8 22.Ng4 Bg8 23. Ne x f6 BxN 24.Qd2!; or if 21…h5 22.g4! g5 23.gxh5 Rh8 24.Ng4  etc.

ch-CHN(w) Xinghua  2016.4.18  Tan, Zhongyi -Zhang, Xiaowen : 26.Bxe6!!  This strong move completely shatters the Black King’s defences. 26…fxe6 27.Qxe6 Be2 Otherwise Rd7 wins immediately; and if 27…Bc8 28.Ng6+ will force mate. 28.Ng6+ Kh7 29.Nxf8+! Rxf8 30.Rd7 Qxd7 31.Qxd7 Bxh5  Black has 3 pieces for the Queen, but White has seen further than his opponent 32.g4! Nf6 (Or if 32…Bg6 33.f5 Bf7  34.Qe7 etc )  33.Qd6! Re8 34.gxh5 and the rest is easy: 34… Rxe3 35.Qxc6 Nxh5 36.Qc2+ Kg8 37.Qc5 Re1+ 38.Kf2 Nxf4 39.Qc8+ 1-0
