In deep stack games, you should be more interested in protecting your stack over protecting your hand. It's a tricky buisness, but you have to make sure not to pay off when you hit a hand like TP while still extrating enough value from it so you're a winning player.

For low limits, it's usually true that you should become less aggressive on later streets (with deep stacks) and always hoping for a call/fold and never a raise. The fish are only playing their cards, when their hands get pretty, they raise. But until they get pretty, they love to just call.
