What is the correct syntax for having a draw with insufficient material in Chess? I tried

(draw-condition (Black) (total-piece-count 3) (and pieces-remaining 1 Knight) (and pieces-remaining 0 Pawn))

but I just a get a syntax error.

Try phrasing it as the following:

(draw-condition (White Black) (and (total-piece-count 3) (pieces-remaining 1
Knight) (pieces-remaining 0 Pawn)))

Basically, the goal needs to be one condition, and an and expression has and followed by everything that is anded together.

There is a long thread one side before. Look for "Chess(variants): Draw by insufficient material".
