This is one of the few ones where I don't actually understand the moves, they all almost look random.

It's a win for white, so no, it is not a draw.

Here's a PGN of this easy win:

I don't see how white can make any progress.

give me the line where the bishop never moves

The white queen can probably corner the black king in a corner or on the edge, forcing the bishop to move which it would then get forked. And if the bishop moves before hand then the queen may be able to fork the pawn, not sure though. Theres also the fact that white could even sac the queen for the bishop somewhere else on the board and possibly be able to queen the pawn. Even without the white pawn its probably a win since a Queen will always win against a lone bishop. I know this is the defensive fortress for KQKBN:

I was wrong. For the human eye, it looks impossible to win. Just checked the TB and it's actually not hard at all.
