It seems like draw by insufficient mating material needs to be separated out from draw by repetition, although if you only enforce draw by repetition, it will inevitably happen on a board with insufficient mating material.

ChessPeace says "Draws by insufficient mating material is not available because of insufficient theory dealing with the non-standard pieces".

"Play with many new pieces with new abilities not seen in standard chess"

It seems that if the board is currently limited to standard pieces, it should use the standard rules for draws by insufficient mating material. How hard is that? No pawns, no non-standard pieces, no queen, no rook, less than two bishops, and no knight + bishop.

Those statistics are surprising.

Correct, hence part two was required. This went into some of the possible errors that came up
