Title Needed For This Post

Eight teams of 12 gathered at the Tacchi-Morris Arts Centre, Taunton, on Sunday for the Union’s annual Jamboree. Wiltshire won the Open Section with 7/12 points, one point ahead of Devon who were another point ahead of Gloucestershire.

There were 5 teams in the grade-limited section, where Dorset were the strongest team on paper but in fact came last. Somerset “A” came 1st, a point ahead of the Exeter and Torbay Leagues in joint 2nd place. Somerset “B” came 4th.

In both sections, the margins between first and second places were very fine indeed, this game being a case in point. Wiltshire and Devon’s No. 10 players were paired together. White arrived at the board 40 minutes after the scheduled start of play and a minute before being defaulted. Also, conceding 32 grading points to his opponent, he faced an uphill task.

White: G. Williams (Wilts. 138). Black: R. Thompson (170).

In view of the inevitable loss of the Queen, another continuation might have been. 26…Qe1+ 27.Rxe1 Rxe1+ 28.Kh2 Rh8+ 29.Rh3 Rxh3+ 30.Kxh3; if 26…Kh6 to defend the pawn, then 27.Rh3+ Kg7 28.Rh7+ Kg8 29.Qg6+) 27.Rxg5+ Kh8 28.Qh3+ Qh7 29.Rh5 Qxh5 30.Qxh5+ Kg7 31.Qg4+ Kf6 32.f3 d5 Black is fighting a rearguard action and tries to activate his central pawns. 33.Qh4+ Kg6 34.cxd5 Rxd5 35.Re1 Rxe1+ 36.Qxe1 Kf6 37.Qh4+ Ke6 38.Qh6+ Kd7 39.Kf2 c4 40.Qg7+ Kc6 41.Qh6+ Rd6 42.Qd2 The Queen must keep an eye on the pawn advances. 42…b6 43.g4 d3 44.g5 Re6 45.f4 Kd5 46.f5 Re5 47.Qf4 Re2+ 48.Kf1 Rxb2 49.f6 c3 (If 49…Rb1+ 50.Kf2 Rb2+ 51.Kg3 d2 this is probably as close as Black can get to queening, but the Queen is just too strong to permit this). 50.Qf5+ Kd4 51.Qf4+ Kd5 52.f7 Rb1+ 53.Kg2 Resigned, in view of 53…d2 54.Qf3+ and White gets his 2nd Queen with a forced mate to follow. This win was a crucial factor in Wiltshire’s overall win, one point ahead of Devon.

In last week’s bit of Morphy magic, he won by playing 1…Ng3! doubly attacking the undefended White Queen, and whatever he does about it there follows Nde2+ at least winning the Queen, otherwise mating.

This 2-mover was found in the mediaeval book of chess problems of c. 1350 entitled Bonus Socius or The Good Companion.
