checkmate with bishop and king

yes they can one time i beat a bot with just a queen bcz the ruuks were stopping the opponents king from escaping.

the opposition can let their time run out for a draw

I wanna try it now

there is no scenario in which you would have a "lone queen," if you don't have a king you already lost.

It takes careful positioning to checkmate a lone king against a bishop and king. The trick is to force the other king into a corner under your bishop's control. Support the bishop with your king, constricting the opposing king, and eventually delivering checkmate in a corner square of the same color as your bishop.

And, of course, having another piece taking care of the inevitable square that neither your king nor your bishop covers. Either another piece on your side covering the square or a pawn, bishop or knight of your opponent's occupying the square so the king cannot escape check by moving to it.
