Can a knight and pawn win against a bishop?

Sure.  The pawn usually has to be pretty far advanced though, with the stronger side's King nearby controlling the queening square.  Your best bet is to check an endgame manual for specific situations.

Depends if the bishop can attack any square in front of the pawn and have enough space to move back and forth to prevent capture and being forced away from the diagonal.  If it can then it's a draw. If not then it's a win for the knight and pawn.

most positions

Yeah. If the defending king is outside the square of the pawn you have good winning chances, especially if you have a wing pawn. Central pawns are drawish.

 

most in position

 

never encountered such position so this is a new idea. tnx for posting.,

I do not understand why black played 83...Ba8.  Couldn't his bishop just stay at g2 and trade off the pawn and draw?
 Edit: Sorry just realized white was going to block with knight.
