I think Qb3, this is one of the hardest puzzles I've ever seen on chess.com, this would be an extremely good daily puzzle. Qb3 I think is correct because the black bishop is pinned to the black king, and even though the Queen is pinned, it's moving on the same diagonal, and the black king has no safe squares.
time to settle this, this post has gotten over 1400+ comments, it is final, the answer is Qb3#, no more saying the wrong answer, if you continue to say the wrong after this, I will assume that you can't scrrol a few pages of comments and see that the answer is clearly Qb3#
