Puzzle Time

Hi, I've been away for a couple of weeks but now I'm back to test you with some more tricky puzzles. First, how did you go with the last puzzle?

​

Most of you would have seen that if Black's bishop on h2 moves, it will be check form the rook, a Discovered Check. But the bishop is also in the way of Black's queen as well, so the best move is NOT to retreat but sacrifice the bishop by pushing it out the way. 1..Bg1+! which clears the way for Black's queen to come in to h2 to give Checkmate next move.

​Now let's try an even harder puzzle! The answer will be next week!
