Probably pretty easy for people that are better at chess than me (particularly given I've said it's mate in two), but I thought it looked more interesting than your typical mate. Leela Chess, being a neural network, is apparently prone to missing stuff like this, moving straight into it where there was an obviously better (though still losing) alternative (Kd4, as opposed to Kd6).
Ran a bot game (Stockfish vs. Leela Chess Zero) which finished with a nice mate in 2

For bonus points, here is the true winning combination of moves from earlier in the game, which was also tactically interesting (and I'd imagine, quite a bit harder):
Note that there are a few possible continuations after this line, the best for black being losing a rook and a pawn and generally being in a horrible position quickly after the time the end position is reached.
