While working to make NNUEs for Fairy-Stockfish variants, I found out the existence of the variant Snailtrail,
described only in the code in https://github.com/RainRat/Fairy-Stockfi...ariant.cpp
In plain English, it is a 2 player perfet information game on a 7x7 board, each player has only one piece and can move it to an adjacent square like a King in chess, and in the square left behind there is added a wall so that this square is blocked for both players. The first player who cannot move loses the game.
Here is an implementation, based on the similar lud for the game isolation
