Crazyhouse checkmate, 5 in a row

Sometimes I practice against Lichess SF with Crazyhouse/ZH because it is a difficult opponent for me, sometimes its weird moves that puzzle me, sometimes sacrifices or tactics which turn out to be incorrect (when checking afterwards) but which I cannot refute because (too slow, too weak :-) ) my understanding of Crazyhouse is still quite limited. Here I got a pretty nice pawn checkmate by coincidence. https://lichess.org/RyYq5Ks2/white#99
