NECL update

There have been a number of excellent results for the club in recent matches. The C team drew 2-2 with Clacton A, despite being out-graded on every board. Felix Schnell won on board 1 with Clive Bellinger and Phil Daley drawing on boards 2 and 4.

The D team went one better with a 2.5-1.5 win against Braintree C even though they were out-graded by more than 30 points on every board. Adrian Catrinar won his first graded game, Brian Remmer won on board 1 and John Duff-Cole sealed the team win with a draw on board 2.

The A team have reached the final of the knockout with a comprehensive 3.5-0.5 win in the quarter-final against Witham A and then drawing 2-2 with Brentwood A in the semi-final but progressing due to wins on boards 2 and 3 from Norbert Voelker and Nathan Barnes. Brentwood A fielded the league's only International Master (Richard Pert) on board 1. The final will be against Writtle A whose semi-final opponents (Braintree B) defaulted 4-0.

Perhaps most surprisingly, the B team beat regular Division 1 winners Writtle A 3-1 with wins for Nathan, Svein Kjenner and Felix on the top three boards. The key parts of Felix's and Nathan's wins from this match are shown below.

The computer agrees it is best.} 14. Qxe5+ $1 { Alternative moves are too passive and mean Black has no problems. If anything Black would have a slight edge with his pawns controlling the centre.} Kf7 $1 $11 {The only move that makes the pawn sacrifice work - it allows Black to use his rook and queen on the open files in the centre where White has an exposed King on the e-file and two pieces waiting to be skewered on the d-file.} (14... Kd8 $2 15. O-O-O Re8 16. Qg3 {Black is in trouble with his king stuck in the centre and will soon be more than a pawn down in material.}) (14... Kf8 $2 15.

Qg3 $1 {White had limited options due to the loose bishop on d3 and the pin threat. I spent a long time checking this move - my original intention after playing 13.Qe4 had been to play Qc3 in this position. Qc3 (and Be2) are okay but Qg3 is better as the queen is actively placed and potential skewers along the e-file prevented.} (15. -- Re8 {[%cal Re8e1] wins queen for rook.}) 15... Re8+ {Slightly better than Rd8 trying to take advantage of the slightly awkward minor pieces on the d-file.} (15... Rd8 16. Nf3 $1 {and the bishop is protected by the knight fork.} Qxd3 $4 17.

Bxe4 $2 Qd2+ 21. Kb3 Rxe4 $15) 20... Rxe4 21. Qf3+ $1 {The move that Black must have missed when playing 18...Be4. This zwischenzug is the only move that gives White a winning advantage.} (21.
