My draw against Chessmaster 10th edition

You must be better in the final position with all that pressure against b3. I would've played Qa8 or R4b6 to continue the game. 

It maybe would have been a technical chore to try to make anything of this position, maybe this would be one of those endgames that would be played out for fifty more moves and against Chessmaster I'd not be able to make a single mistake the whole time, and what if it organized an attack on my king? Its rook on c7 and Queen on c2 looked very well placed, maybe f5 could be a potential lever in some situations. if I were to keep playing sooner or later something would have happened. Chessmaster's hammer is always lurking, ready to come out of nowhere and wallop me upside the head. And I'm not going to win from here,  it's just pressure against one a weak pawn. Don't they say you really need two weaknesses to win?
