Thanks! You're right to assume I went for the "20 moves"-count to save time :-). I found that sometimes games just went on forever and made the rule to force action, but perhaps I should revisit that rule if it makes the game end prematurely too often.
My main issue was that if I was down a single pawn, it was really hard to progress and catch back up and the opponent could just make it really hard to capture a single piece without making an even trade (or maybe the AI is just really good lol).
So it ended the few times I played that I would lose technically early on by going a piece down by a single mistake :D (because a draw ends in a win for them by being that piece up)
