Using small bait to mate

Please post games where mate is achieved suddenly when the opponent takes a small bait (poisoned pawn, opened lane, chased piece, etc.). Thanks!

Ok, it was a bishop sacrifice as my poisonous bait !

A hidden agenda behind my interesting bait (knight+bishop=mate)

To be honest, I'm not 100% sure that this qualifies for this post, but I like the race here that sets the mate in motion:

Here, in the endgame, the bait was to slip the king into a spot where a knight check seems natural, but a queen-bishop fianchetto applies mating pressure for the win.

Why not 18...Rxf2 immediately?
Also more pedestrian moves, like 18...Be5, are terminal.
Because on Rxf2 immediately white still has Qe1 with a lousy endgame to defend.
Be5 is better. After Rb1, Rxf2, Qe1 black has Qxg3 (because of Bd4).
c4 was a "bad" move because this allows white to organize some kind of defence with Qe1, Qxc2, Bf3

Nicely done, Ronald. I like how you played the fianchetto reveal on the corner bishop. Like fishing, baiting often means "dangle, dangle" and "wait for it, wait for it," then "hooked!" Fun!

In this game, a naturally renegade queen ends up biting on poisoned pawns and a knight, leading to her being dropped and, upon going for the trade, falling victim to a snap mate. I think up 1/2 tempo at move 10, and 16. Nxg6 wins!
I don't have the full game, just this combination saved on my phone. Also, I don't mate but my opponent greedily takes a pawn and I then make a serious of combinations to win his queen :) I'll post it as a puzzle for fun.
