this is a possible checkmate
Should this be draw?

This site doesn't use FIDE rules, under which those should not be draws. I agree it's a problem. Like I posted in the other thread a forced knight vs pawn endgame one side could flag and get a draw out of a forced mate position due to one or both sides pieces being considered "insufficient"
At any point white could stall and get a draw by flagging himself. Based on this sites rules.
On chess.com, a bishop vs knight endgame will always end in insufficient checkmate material draw, but that’s actually not true, theoretically there could be a mate if you blunder
