Palliser-Dineley
Barbican vs. South Wales Dragons
Notes by GM John Emms

1 d4 Nf6 2 c4 e6 3 Nc3 Bb4 4 f3
An ambitious line which immediately fights for the control of the important e4-square. 4 f3 was a favourite of Alexei Shirov's, but it lost its popularity (perhaps unfairly) a few years ago after some high profile losses. 4...c5 5 d5 b5 6 e4
6 dxe6 fxe6 7 cxb5 d5 gives Black good compensation for the pawn.
6...bxc4 7 Bxc4 Nxd5
This little trick is all established theory.
8 Bxd5
After 8 exd5? Qh4+ picks up the bishop on c4.
8...exd5 9 Qxd5 Nc6 10 Be3!?
This looks new. 10 Nge2 is the normal move. 10 ..Ba6 11 Be3 Rb8 12 Rd1 0-0 is given in ECO as unclear.
10...Qb6
10 ..Rb8!?.
11 Kf2
It looks strange to give up the right to castle, but the king is quite safe on f2.
11 ..Ba6 12 Nce2!
More ambitious than the normal looking 12 Nge2. White makes use of the strange move-order and now the bishop on b4 is in danger of being left out of the action.
12...Qb5 13 Nf4 0-0 14 Nh5!
Suddenly Black's kingside is looking very short of defenders. The big threat is Qg5. Black tries a tricky defence, but White is ready.
14...Bc3?
This tricky looking move loses by force. 14 ..Nd4 looks like a better defence. Then 15 Nxg7 Kxg7 16 Qg5+ Kh8 17 Qf6+ Kg8 is a draw by perpetual check, as after 18 Bh6 Ne6 Black defends.
15 bxc3! Qb2+ 16 Bd2 Qxa1
Black has won an exchange but now it's White's turn to bat...
17 Qg5 g6 18 Qf6! gxh5 19 Qg5+ Kh8 20 Qf6+ Kg8 21 Bh6! Qxa2+
Or 21 ..Qf1+ 22 Kg3 Qe1+ 23 Kh3 and Black has run out of checks.
22 Ne2! 1-0
Perhaps Black missed this move when playing 14...Bc3. 22 ..Qxe2+ 23 Kg3 h4+ 24 Kh3 and Black cannot prevent mate. But not 22 Kg3? h4+ 23 Kh3, which allows 23 ..Qe6+ and Black wins.
