Three things:
1. If this guy was in the BB and it was only 150 more for him to call, he would have been makign a "bad play" by folding any two cards here.
2. It's is possibly (And very probably, IMO) that all your Play Money practice has hurt your Real Money game, and will take you a lot of time to overcome. All playing for Play Money does is reinforce bad habits and bad poker. If you do it for fun, more power to you, but realize that real poker is much different.
3. For anyone think about buying poker books online, I've got affiliate links for that too!
