.SH "DESCRIPTION:"
This program is a stand\-alone Syzygy tablebase probe tool.
.br
The program takes as input a FEN string representation of a chess
position and outputs a PGN representation of the probe result.
.PP
In addition to the standard fields, the output PGN represents
the following information:
.br
\- Result: "1\-0" (white wins), "1/2\-1/2" (draw), or "0\-1" (black wins)
.br
\- The Win\-Draw\-Loss (WDL) value for the next move: "Win", "Draw",
  "Loss", "CursedWin" (win but 50\-move draw) or "BlessedLoss"
  (loss but 50\-move draw)
.br
\- The Distance\-To\-Zero (DTZ) value (in plys) for the next move
.br
\- WinningMoves: The list of all winning moves
.br
\- DrawingMoves: The list of all drawing moves
.br
\- LosingMoves: The list of all losing moves
.PP
The PGN contains a pseudo "principle variation" of Syzygy vs. Syzygy
for the input position. Each PV move is rational with respect to
preserving the WDL value. The PV does not represent the shortest
mate nor the most natural human moves.
