How to mate with queen + king vs bishop and king?



This could be very frustrating especially when you are new to the game like you said.
Try creating a boundry for the king on Qh4 and then move your king until you get to
Kf4. That way, you can separate the king from the bishop and corner the king as you decrease the boundary space of the black king.
Could take time but it sure is the best way if you want to win without a stalemate. :>)

I got into this position but managed to win thanks to time
I'm curious about what you meant by this. Did you have a queen against a bishop, and didn't know how to win, but won anyway because your opponent ran out of time?

Box in the defending king and keep your king and queen on the squares opposite the color of the bishop. It is an easy win. The bishop will be totally overwhelmed by the queen. Here is a demonstration of how it is done:

Okay I'm replying 17 years later but what I would do in this situation is to fork the king and the bishop. When the king moves out of check then capture the bishop and do a normal king and queen checkmate. It should be easier after the pressure of the bishop is gone. (hope that helped, here's a picture to show you)

cant black just save the bishop by blocking?
I'm totally new to chess, and I just ended up in this position - how should I have won? I got bored before I figured it out, but I assume it's possible?
