This is an experimental Nalimov Tablebase Server. All 3,4, and 5 piece endgames are available. To
use it just enter a FEN string in the box above and press the submit button or
setup a position by dragging the pieces. After a short
time the textbox will show the result for the position and results for the possible moves.
Result is the distance to mate or 0 if the position is a draw. 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. After that you will receive the new position with the
new scores and moves.
For programmers; the service is also accessible from
within your own application. See here for
information.
Notes:
If the server has not been used for some time, the initial response may
take a bit long.
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.
This version requires IE4.0 or higher, if it does not
work you may access the old version here...
