In the Queens Division, the Hurricanes faced a team of strong Battersea junior players, one of whom featured in our 4-0 defeat to Battersea A in season 1. An interesting idea to run an all-junior team, but thankfully at Hendon we have some very decent juniors of our own, three of whom featured here alongside Rob!

The match didn’t start well, with Rob blundering a mate in 1 in a much better position. However, Alex Leslie struck back by converting an endgame after his opponent had unwisely traded queens and let his c-pawn go.

So everything rested on what happened with Kennan and Sacha on the top and bottom boards.

Kennan seemed to be doing well, with two bishops against two knights; he won a pawn and traded off into a winning king-and-pawn endgame – which he duly won – and it appeared we were on the verge of victory.

On Board 1, matters were far less clear, as Sacha was embroiled in a crazy back-and-forth struggle. I had no idea who was better from one move to the next, though the game eventually seemed to have settled in Sacha’s favour when he won a piece for two pawns.

But there was still drama in store, as Sacha was very short of time, and the position remained difficult, as Sacha didn’t have many pawns left, while his opponent’s were steadily advancing. The game reached boiling point with Sacha having less than a minute on his clock, while his opponent still had over ten minutes. Right at the death, Sacha went wrong, capturing a knight and allowing his opponent to queen.

Thus, the match ended in a tie. We were very unfortunate not to win here, as we had excellent positions in both the games we lost, and on another day we’d have taken at least a half-point from them.

I hate to dwell on the negatives in the analysis below, but the fact is that Alex and Kennan both won fairly smoothly; they showed good technique, but their wins contain fewer points of knife-edge drama and interest than our two defeats…

In the Bishops Division, the Spitfires were aiming to extend their 100% record in season 2, against the Hackney Hopefuls. On paper, we looked to have the stronger team, but you can never be too sure, as the official grades are quite stale now!

Anton got us off to a great start with yet another win on bottom board, keeping his head to pick off his opponent’s advanced pawns in a rook ending, forcing resignation.

Chris’s position looked dodgy at one stage, with his opponent’s rook infiltrating down the b-file, but for some reason the Hackney player didn’t do it, and Chris seemed to have recovered. I thought he had excellent winning chances after that, but ended up taking a repetition in a tricky knight ending.

This left us still needing a full point more to win the match, with both David and Alex having ropey-looking positions. David had been a pawn down since a very promising opening had fizzled out. In a topsy-turvy ending, he recovered from his disadvantage, and his opponent even blundered late on, giving David a chance to win the bishop ending, but David had already reconciled himself to a draw and traded everything off.

I thought Alex was just straightforwardly worse, but looking at the position afterwards, that’s not the case, and there were several draws available. However, Alex needed to play accurately, with his opponent having an outside passed pawn in the rook ending, and he sadly went down in the end.

This meant we only drew the match. Once again, we can consider ourselves unfortunate, as we had serious chances of picking up an extra half-point on all three boards. We can only hope the Spitfires won’t come to rue these missed opportunities at the end of the season!

Several games in this match had instructive endings, which are worth examining.

Further down the Bishops Division, the Harriers looked heavily outgunned, against one of the top sides, Streatham & Brixton B. So it proved, as Dev was swiftly mated, and Berenbluts Junior and Senior both gave creditable accounts of themselves but ultimately couldn’t match their opponents.

On Board 1, James Baxter bravely chanced his Latvian Gambit once again, and while he ended up with a rotten position, he did have compensation on the clock, when his opponent astonishingly took 15 minutes (of 45 initially available) on move 9! James survived the opening, but still looked as if he would lose, the exchange down in an ending. However, his opponent’s clock caught up with him and he went wrong, allowing James to make a draw, putting a smile on Harriers faces!

All round 5 games in the Bishops Division are currently available here.

Many thanks to all who played!
