However, this year’s DivP was extremely entertaining and captivated my attention from beginning to end. The format was slightly odd as – in order to save costs on the hiring of the GPU server – all CPU machines games were played first. The downside was that the exact ranking order was shrouded in mystery until the very end due to the differing numbers of games played by CPU and GPU engines. On the other hand, organising the games in this fashion did reveal some interesting trends and contrasts.","PeriodicalId":14829,"journal":{"name":"J. Int. Comput.

Here, following Lasker and Reti, we propose that ‘stalemate’ is a secondary goal, superior to a draw by agreement or rule – but inferior to mate. We report the work of ‘Aloril’ who has created endgame tables holding both ‘DTM’ depth to mate and ‘DTS’ depth to stalemate data, and who should be regarded as the prime author of this paper. Further, we look at the classification of ‘Chess Stalemate Studies’ in the context of a ‘Lasker Chess’ which recognises the stalemate goal.","PeriodicalId":14829,"journal":{"name":"J. Int. Comput.
