4NCL Echoes: Mating By Two Knights
Jim's opponent, Malola Prasath (2076), gained a small advantage in the ending King, Bishop & Knight and pawns against King, two Knights and pawns.
Jim did not want to suffer and he decided to sort his problem radically and he sacrificed both light pieces and went for the ending King & Pawn vs King & two Knights. It was brilliant defensive idea but the move order should have been slightly different perhaps. Let's have a look at what happened in the game:
So was there anything what White could have done better? Well, like I said, the same idea, but several moves later...
Theory of this ending is very much connected with the name of Russian theoretician Alexey Troitsky who analysed similar positions quite extensively and came up with his idea of so called "Troitsky line". Troitsky established that if a pawn is blockaded (by one of the opponent's Knights) on a square no further forward than the line a4–b6–c5–d4–e4–f5–g6–h4, then stronger side can win the resulting endgame no matter where the other pieces are placed. However, the checkmate procedure is difficult and long. In fact, it can require up to 115 moves, so in competition often a draw by the fifty-move rule will occur first.
Since many of the wins when the pawn is blocked on or behind the Troitzky line require more than fifty moves (and thus would be draws under the fifty-move rule) Karsten Müller asked for the "second Troitsky line", which corresponds to where the knights can win without the fifty-move rule coming into effect. If defender's pawn is blocked by an attacker Knight on or behind one of the line, White can force a win within fifty moves. In details, read the article under this link, and also two volume article written by Karsten Müller (The Damn Pawn Part 1 & Part 2) for Chesscafe.com.
So have we learnt anything from this above mentioned game? Well, my opinion is that only player with two Knights can play for win and therefore no matter what theory says he can play until the draw according to 50 move rules can be claimed. In over-the-board game, a defender can slip any time, and only the defender is under double pressure - pressure from the position and pressure from the running time.
4NCL at Staverton Park: Pandora's Box Grantham Beat Wessex But Lost to Poisoned Pawns
It has been lovely weekend in the De Vere Hotel, Staverton Park at Daventry where round 5 and 6 4NCL, Division 1 & 2 were played.In division 2 I had a pleasure to make my debut playing on board 7 for Pandora's Box Grantham and for the team I won 1 point by making two draws.
Saturday afternoon Pandora's Box beat Wessex after tough fight, alas, on Sunday was defeated by Poisoned Pawns.

NCA League: Grantham-1 Beat Mansfield-1
Last night, Grantham-1 hosted Mansfield-1. The match was tight nearly down to the wire. The games on top boards were very tough, and the game on the board two became a little drama in time trouble where both players, Nigel Birtwistle and Jim Burnett, played "to the Kings". Technical draw was claimed when only 2 seconds left on Nigel's clock!!!

Claudio Mangione, playing with Black against Jonathan Tait, suffered a bit in the Modern Defence. In the Queenless middlegame White was definitely better. Then he came up with excellent move 34. Nd6! Three moves later Jonathan failed to find the best continuation and Claudio equalised. Then probably both players run short of time and the game looked like a roller coaster ride. Jonathan made a serious mistake an his position was very likely lost. Several moves later Claudio returned the favour and his position became lost. Finally, Claudio miraculously escaped from defeat. By the whisker but very intersting game!
Grantham got the edge when Nick Payne overplayed Kenneth Morrison. Nick, playing Black, had face up to Alapin Variation of Sicilian, he chose for aggressive set up with 2...d5 followed by 5...e5?!. The game took 18 moves only, because in worse position Kenneth blundered Bishop.
Chris Canthrill played against Steve Prior very good chess and in French Defence he obtained a promising position, however, he missed his chance to play for more around the move 23. And then it was Steve's turn to fight for an advantage. And he did so and achieved massive positional advantage if not even winning position. Alas, he did not find the strongest possible continuation and the game eventually ended up draw in opposite coloured Bishops and Rooks ending.
I played against Janos Wagenbach who played with White pieces a very solid opening. Fianchettoing his light-squared Bishop he played for a solid position. Both player then complicated the game. In move 14, Janos chose for queenside expansion overlooking much better option which would have led to destruction of Black's position.
Then, to eliminate Black's pressure along c-file, Janos decided to exchange all heavy pieces and on the board an interesting ending appeared. Having had Bishop pair and Knight Black played against two Knights and Bishop. However, because of closed character of the position it is very difficult to claim any substantial advantage for Black. From the move 50 on, both player were short of time. Under time pressure Janos made several weak moves and finally he blundered a Knight and eventually lost the game.
