how to win this queen v bishop and pawn

This is the correct solution to a puzzle

White gets a queen versus bishop and pawn, but then what? How does white win this?

If white captures the bishop black gets a queen next turn.

if white moves his queen to b1 or c2 then brings his king to join the attack black can retreat on the long diagonal and still protect the pawn

The analysis board says white's queen check check checks the king but I don't see how that goes anywhere

Thanks

If you in the analysesboard click on the right tab named 'tablebase' you will be demonstrated the win. My guess is that White will 'simply' mate Black with the King and Queen.

By the way I understand your frustation. I experienced somthing similar when studying Rook-endgames, where some variations just ended in the winning position: Queen (promoted pawn) against Rook + Pawn, wich is actually dead hard to win at my level.

I didn't know about tablebase

Thank you

I think the strategy is: white puts his king on b1 then tries to fork king and bishop

"white puts his king on b1 then tries to fork king and bishop"
++ No. White puts his queen on the diagonal b1-h7 and/or the b-file to stop the pawn b2 from queeing and then approaches his king to checkmate the black king.

hmm

The fish whispered "mate in 23"

This is a win.
