If you find mate in 1, you’re a genius 🧠

Qb7# or Qc7#
or Qb3#
I am now going to edit this comment 5 months later to say that THE QUEEN IS
5 more months later I edit again
The queen is pinned but can still move along the g8 to b3 diagonal, due to moving to those squares not allowing the black bishop to check
Rxg8+ can be blocked by the black queen, so can Bh2+ and Qxg8+
The only other way to check without the black queen blocking is Qb3#. The black bishop cannot capture the queen because it's being pinned by the rook.
If the black bishop captures it, the rook will take the black king BEFORE the white king is captured, because the winner is whoever checkmates or captures the opponent's king FIRST

Too complicated fr

Well, Qb3#, but it's not genius move. It's quite easy to see even for beginners like me who just play hundred of puzzles and lost tens of games to the bots.

That´s really easy, the queen is pinned 📍 by the bishop, but the bishop is pinned also by the rook, so Qb3# the king can´t take the knights because of the other bishops, and the bishop can´t take because of the rook

just move the white rook to capture the enemy bishop trapping the opposite king inside the barrier rook and queen lines but since this is rigged to the point of no return then we are all smart
edit i now understand that my previous statement is wrong. for that I formally apologize that their has to be a single correct move and i realize that qb3 i in fact the correct move for having check in 1 don't take with the rook because the opposing opponent can move queen to block making you move again if you really want to win use the Qb3# method for mate in 1 because if anyone wants to challenge this saying "they can just take with the black bishop" the black bishop is pinned from the white rook and the two knight are also safe from elimination or capture from the two bishops leaving the king only one square the square he is currently in after moving the queen to Qb3 it ends in a check mate with the final result ending as Qb3#.
I missed Q B3. I think that's it.
