Preflop: I like the limp, for the reasons Niss said.

Flop: Standard. You have the nut low draw with protection, you have enough equity for a raise to be profitable.

Turn: Your card did not hit, and now you are left only 1/2 the pot and just one card to come. This is the point where I go into a check/call mode. Give me A9h or something working for a high and I think a bet is profitable.

River: Fine.

Overall: You played the hand fine, no real problems. I would have just c/c the turn, but thats not a huge deal.
