Pre I think is standard. On the flop vs small bet and with draws possible I think its ok to call closing the action.

Turn gin and I check raise small. I'm really not keen on this now. At the time I was thinking I could get some calls from 7x, T8 or some NFD hands but in hindsight I think am I really getting anymore money I wouldn't have got by calling and putting my raise in on the river, especially if a heart drops. I may just be isoing myself vs the nuts, and scaring weaker value hands away from putting chips in on the river.

As played river bet I think is mandatory.
