An algebraic version can clearly be employed, but due to the size of a 4H board, can involve a lot more counting! With descriptive notation, all ranks are described from the view point of the player whose turn it is to move. Squares in the board extensions to either side of each player are expressed as that of the player concerned, given in a lower case letter before the square eg yK3 means Yellow's K3, rKB3 means Red's KB3 etc. The same device is used if necessary to avoid an ambiguity, sometimes in relation to a piece, eg bKN means Black's king's knight, etc. A player who is mated loses his turn and his "move" is therefore shown as a dash.

Game 3 Round 2, Board 1 Cambridge: Andrew Ponting (White) and Philip Best (Yellow)London: David Sedgwick (Black) and Tony Paish (Red)      White      Black      Yellow      Red  1   P-K3       P-K3       P-QB3       N-QB3? The Cambridge players had come up with an opening novelty (yP-QB3) and Red fails to see its point. On the other boards, the London players also found themselves confronting this position and fell into the same trap!  2   B-Q3       Q-K2? On the other board, Black found the correct move, which is 2 ..., Q-N4, only to go wrong, however, two moves later!  2   ....       ....       QxP mate      - 3   Q-R5 This move, which is prevented by 2 ..., Q-N4, allows a subsequent Q-R9 upholding the mate.  3   ....       Q-B4       P-K3          - 4   Q-R9 With the mate consolidated, Black is left to fight the combined White and Yellow forces single handedly, morevore, having one move to their two! It is only a matter of time.  4   ....       QxQ        BxQ           - 5   P-QN4      P-QN3      P-KR3         - 6   N-QB3      B-N2       B-K10         - 7   KN-K2      BxB        N-KB3         - 8   NxB        P-QR3      P-KR4         - 9   KN-QB3     PxP        RxP           -10   P-KR4      N-QB3      R-K4          -11   P-R5       R-N1       R-K5          -12   R-R3       N-N5       NxN           -13   R-B3       BxN        K-K2          -14   BxNP       Black and Red Resign. London 0 - 3 Cambridge Game 4 Round 2, Board 2 Cambridge: Dave Boyle (White) and Natasha Regan (Yellow)London (Insurance): Ian Hunnable (Black) and David Malcolm (Red)     White      Black      Yellow      Red 1   P-K3       P-K3       P-QB3       N-QB3? See note to previous game. 2   B-Q3 yQxrP mate cannot now be prevented, except by bBxP+, giving up a piece. However, Black saw a means of playing so as to subsequently raise the mate without giving away material: 2   ....       Q-N4! ...so as to follow with 3 ..., Q-QB4. 2   ....       ....       QxP mate      - 3   Q-N4       Q-QB4      Q-N9        P-K3 Black and Red are out of the woods at the cost of a red pawn. Black, however, was about to plunge them back into the mire... 4   Q-B8 Now Black managed to convince himself that Red was under threat of mate by wQxKP+ and yQ-N3 mate. (This neglects to take into account that Red has a move in which to defend against this threat.) Under the misapprehension that it was vital from him to lend support to the Red camp, he played... 4   ....       Q-B13?? ...which turned out to be the biggest blunder of the entire event! Correct was 4 ..., N-KB3, for as White & Yellow swiftly demonstrate, it is Black who is threatened with mate! 4   ....       ....       QxbP+       Q-B3 5   QxbQP mate   -        Q-N12+ ...releasing the mate so that White can capture the Black pieces. A simple strategy: Yellow keeps Black in check allowing White to mop up the bits; it is a lot easier to win if you can render one opponent impotent rather than having both queens tied up in maintaining a mate. The game concluded: 5   ....       ....       ....        Q-B4 6   QxB+       K-K2       Q-bK1+      P-QN4 7   QxN        K-B3       QxB+        Q-KR4 8   QxR        K-K4       P-QN3 ...cutting out the mate by 8 ..., ..., ..., Q-yQ1 mate.                Black & Red Resign.
