In 2005, 6-piece endings were solved in Nalimov Tablebases which are now used by many professional chess programs and services. In the beginning of the 90-s, the same task was done for 5-pieces. Source code of Scorpio bitbases compressor and probing code is available. The first ending tablebases for all 4-piece endgames were built by the end of the 80-s. Run some endgame tests to see if the engine is really using those bitbases. Moves are now sorted by there scores, best move(s) are displayed first.Īdded proper handling of en-passant status.(330 MB) After you downloaded them, check their integrity with the included MD5 files, move all 3-4-5 files and 'egbbdll.dll' into single directory, and point your engines to that directory. Sample position: 1k6/3K1p2/8/8/8/8/P5P1/8 w -įixed bug with duplicate moves when position contained a black bishop.įixed problem where a illegal position could make some tablebases inaccessible. This would sometimes return incorrect results in positions where a double pawn moves was possible but did not lead to e.p. You may send your suggestions and feedback through our feedback pageįixed bug en-passant status bug. Positions where castling is still possible are not in the Tablebases, therefore entering a position where castling is possible gives a result as if castling is not possible.

After that you will receive the new position with the new scores and moves.įor programmers the service is also accessible from within your own application. This computer was equipped with 52,168 x86-64 cores, 954,840 GPU cores, and 92 TiB of RAM for a peak performance of 1.7PFlops, which is the approximate equivalent of 150 1080 ti GTX cards in parallel (at 11.3 tflops each). You may carry out one of the moves in the list by selecting the move of choice and pressing submit or by double clicking the move. According to this page, the 7-man tablebase was calculated in 6 months by the Lomonosov super computer in 2012.

Result is the distance to mate or 0 if the position is a draw.
