Here is the game between a Devon newcomer and a Somerset regular.

White: M. O. Marshall (166). Black: A. A. Champion (153).

1.c4 b6 2.Nf3 Bb7 3.Nc3 g6 4.d4 Bg7 5.e4 White accepts the invitation to set up a strong pawn centre. 5…e6 6.Bg5 Ne7 7.Bd3 d6 8.0–0 Nd7 9.Qd2 h6 10.Be3 Nf6 11.h3 g5 12.Nh2 Ng6 13.Rad1 Qe7 14.Bc2 0–0 Black seems well-defended on the kingside, so White seeks to expand on the other wing. 15.b4 e5 16.d5 a5 17.a3 axb4 18.axb4 Ra3 19.Ra1 Rfa8 20.Rxa3 Rxa3 21.Rb1 Qd7 22.c5 As Black’s b-pawn is pinned he cannot afford any pawn exchanges here, yet is threatened by a potential fork. 22…Qd8 23.cxd6 cxd6 24.Nb5 Ra8 25.Rc1 Ba6 26.Nc3 Bc4 27.Bd3 Bxd3 28.Qxd3 Ra3?! This rook cuts a lone figure for the rest of the game. 29.Qb5 Nd7?! 30.Qc6 Bf8 31.Nb5+- Rb3 32.Qc4 Rb2 33.g3 Qa8 34.Qc6 There now follows some repetition with the aim of reaching the time control at move 40 as quickly as possible. 34…Qd8 35.Qc4 Qa8 36.Qc6 Qd8 37.Ra1? Or 37.Nxd6 Rxb4 38.Ng4 h5 39.Nb7 Qe7 40.d6 Qe6 41.Qxd7 Qxd7 42.Nf6 etc. 37…Rxb4 38.Ra8 Qxa8?! 38…Nb8 39.Qb7 Rxb5 40.Ng4 Kg7 41.Rxb8 Qe7 42.Qc6 Rb4 43.Bxb6. 39.Qxa8+- Rxb5 Black has lost his queen, but has a rook, knight and pawn for it, potentially roughly equivalent, though Black’s minor pieces are very cramped whereas the queen has open lines to exploit. 40.Kg2 Nc5 41.Ng4 Kg7 42.f3 42.Bxc5 bxc5 43.Ne3. 42…h5 43.Nf2 Be7 44.Qb8 Nd7 45.Qe8 Attacking the pinned knight. 45…Rb1? Better was counter-attack via 45…Rb3 46.Nd1 Rd3 47.Qxd7 Rxd1 48.Bxb6 46.Qxd7 b5 47.Qf5 f6 48.h4 gxh4 49.Qxh5 Qh6+ & Qh7. 49…Nf8 50.Bh6+ 1–0. Black resigned in view of 50…Kg8 51.Qe8 and Black must lose more material.

The key to last week’s 2-mover by John Brown was 1.Qe7! If 1…Bxf4 2. Be4#, or 1…Kxf4 2.Qf6#, or 1…Bf3 2.Qxf7# and finally 1…Bg7 2.Qg5#.

In this position from a game earlier this year Black is a piece up but is about to be mated unless he can find a move that not only avoids mate but maintains his material advantage. He succeeded; can you see how?

Black to play

Sicilian Defence – Closed System.

1.e4 c5 2.Nf3 g6 3.d3 Nc6 4.Nbd2 Bg7 5.g3 d6 reinforcing e5. 6.Bg2 Rb8 7.a4 a6 8.0–0 Bd7 9.Re1 b5 10.axb5 axb5 11.Nb3 e5 12.Bg5 Bf6 13.Be3 Bg7 14.c3 Preventing intrusion by Black via b4 & d4. 14…Nge7 15.d4 c4 Black attacks the knight and wins space but White has a positional sacrifice in mind. 16.dxe5 cxb3 17.exd6 Nc8 18.e5 For the knight sacrifice White has a protected passed pawn on d6 and the more active pieces. 18…0–0 19.Bg5 Qb6 20.Qxb3 White now has 3 pawns for the knight, a balance of forces favouring White. 20…Be6 21.Qd1 Nxe5? If 21…b4 Black could hope to survive. 22.Nxe5 Nxd6? Better was 22…Bxe5 23.Rxe5 Nxd6. 23.Be3 Qc7 24.Nc6 Rb7 24…Ra8 hoping against hope 25.Rxa8 Rxa8. 25.Bf4 White’s pieces all have long lines and diagonals, while Black is losing material. The pin on the knight is fatal. 1–0. Play might have continued 25.Bf4 Re8 26.Qxd6 Qxd6 27.Bxd6+.

The West of England Inter-County Jamboree took place on Sunday at the Tacchi-Morris Arts Centre, Taunton, with, like Paignton, a lower than usual entry. Devon retained the Congress Cup for the top section with 8½/12 points, followed by Somerset (6) and Cornwall (3½). The grade-limited section was won by the Torbay League (7½/12), followed by Gloucestershire (6) and Somerset II (4).

Last week’s 2-move miniature by David Howard was solved by 1.Qg1! threatening 2.Qg5 mate. If 1…Kxh4 2.Qh2 mate.

Here is a 2-move finish by Keith Arkell from a game earlier this year. If it seems relatively easy from this point, the skill lies in reaching the position in the first place.

White to play and win.
