A Recent Nunn Win & WECU Junior Winners (25.03.2017.)

Grandmaster John Nunn’s unexpected appearance at the recent East Devon Congress undoubtedly created some extra interest in the event, and he didn’t disappoint, coming clear 1st with 4 wins and finishing with a draw. This was his game from Rd. 3.

White: Stephen Piper (187). Black: John Nunn (236).

Grünfeld Defence [D79]

1.c4 Nf6 2.Nc3 g6 3.g3 c6 4.Bg2 d5 5.cxd5 cxd5 6.Nf3 Bg7 7.0–0 0–0 8.d4 Ne4 9.Qb3 Nc6 10.Rd1 Na5 11.Qb4 Bf5 12.Nxe4 dxe4 13.Nh4 Bg4 14.Bxe4 Bxe2 15.Re1 Ba6 16.Bg5 Re8 17.Rad1 Rc8 Grabbing the open file with a rook – a contributory factor in Black’s win. 18.b3 b6 19.Ng2 Qd7 20.Be3 Bb7 21.Bxb7 Nxb7 22.Nf4 Nd6 23.Nd3 Rc2 24.a4 Nf5 Black must have calculated carefully that his advanced rook cannot become trapped and picked off. 25.Ne5 Qd5 26.Nc4 Rd8 27.Na3 Rb2 28.Nc4 Ra2 The rook cuts a lonely figure on a2, but cannot be taken, so must lie quietly. It doesn’t move again. 29.Rd3 e6 30.Red1 h5 As the White pieces are situated in the centre, Black chooses this moment to attack White’s king’s position. 31.Qe1 h4 32.Qf1 hxg3 33.hxg3 Qe4 34.Qg2 Qg4 35.d5 exd5 36.Rxd5 Just as White’s rooks break free for their self-imposed constraints, Black strikes. 36…Qxd1+! 37.Rxd1 Rxd1+ All other things being equal, two rooks are generally deemed to be stronger than a queen, providing they have scope to move and can cooperate, as is the case here. 38.Kh2 Nxe3 39.Nxe3 Rdd2 40.Qa8+ Kh7 41.Qxa7 Rxf2+ 42.Kh3 f5 Blocking off g5 as a possible escape route. 43.Kh4 Rh2+ 0–1 Resigned in view of 44.Kg5 Rh5+ 45.Kf4 Rf2#.

The West of England Congress starts a fortnight on Friday in Exmouth, with entries currently standing at 60 and rising. Time, therefore, not to risk missing the cut-off by getting entries to the Secretary, Meyrick Shaw, (tel: 01395-275494 or e-mail: wecu@hotmail.co.uk. Entry forms are downloadable from chessdevon.org.

The solution to last week’s 2-mover (above) was 1.Qe7! threatening 2.Qh4#.

This week’s position came from a recent game played in the 4NCL. As with 2 rooks vs a queen, Black’s 2 minor pieces should be slightly stronger than a rook, all other things being equal, but in this case they are not, as White has the opportunity to sweep away this slight inequality. How so?

White to play & win quickly
