call or raise on flop depending on circumstances.

turn seems like a really easy check behind. All pairs 88 and higher now have you crushed, along with Tx. I don't understand your river bet at all, unless it's as a bluff to move him off a bigger pair (why you'd ever try moving someone off a bigger pair on this board is beyond me, but whatever). I also don't see what the decision is when you are raised big.

Also, when you are the first person to put money into a pot on a given street, you are betting, not raising.
