I need a five move mate plsss
I only made because they asked for 5 move mate

The White Queen was on a6.
Black had pawn on a5.
White Last move was playing Qxa6.
——————————————
This is a position I had in a Chess Game.
I burned up a lot of time in this position.
My Killer Chess Instincts knew something was up, but I lost on time trying to find it.
The above position has multiple checkmating variations depending on how White moves.
You have to find the Checkmate for each King move.
The Longest Continuation is 15 moves.
Thus, Black to move - Forced Mate in 15
Can you find it?
