Against an engine that is faster and sees deeper (i.e., Rustic), MinimalChess can also sometimes be axed by a tactical shot. I've seen several positions where MinimalChess is clearly better (but not yet winning), and then it plays a move that is completely obvious from a positional standpoint, but which doesn't work tactically. Often I myself don't immediately see that the move is a mistake until Rustic sacrifices some a bishop and a pawn, plays a few forced moves, and then MinimalChess has the choice of being mated or lose its queen due to a knight fork. Then it's downhill from there. The chance of this happening becomes greater as the game progresses.
Not sure why do you think Rustic is faster and sees deeper than MMC, at least not in ZaTour. MMC sees as deep or deepr than Rustic (maybe because I use the latest dev version?)
This is their last decisive game in ZaTour Season one, MMC's depth is similar (if not better) than Rustic:

I do agree if you say Rustic sees wider, but that is not necessarily a good thing
