In 2005, 6-piece endings were solved in Nalimov Tablebases which are now used by many professional chess programs and services.Įxperts didn’t expect 7-piece endings to be cracked and catalogued until after 2015, but Convekta Ltd, namely programmers Zakharov and Makhnichev – the developers of the Aquarium interface – managed to solve this task in just 6 months using a new algorithm designed specifically for this purpose and run on the Lomonosov supercomputer based in the Moscow State University. In the beginning of the 90-s, the same task was done for 5-pieces. The first ending tablebases – for all 4-piece endgames – were built by the end of the 80-s. This is why there is a limit to how far the calcullations can go with the current level of computing devices. When the piece limit is increased by one, the number of possible situations goes up about 100 times. The main difficulty in compiling such tablebases consists in the fact that all possible positions and variations with the desired number of pieces on the board must be thoroughly analysed and catalogued. If the losing player makes a suboptimal move, he will lose sooner and the program will display the new optimal path. If the game can be won, the path with the least number of moves until the end of this variation is shown, given that both players make the best moves possible. Simply put, the program determines if the position leads to a draw or can be won by either side – with 100% certainty. With Lomonosov Tablebases, this limit has gone up from 6 pieces to 7! What are Endgame Tablebases?Įndgame tablebases are computer databases of chess endings with precise calculations for optimal play in any position, provided the number of pieces on the board does nor exceed a certain limit.
