I would think you need to raise less on the flop, and bet less on the turn.

There are obviously three ways to play this: Aggressively (how you've played here), Passively (check/call for a cheap showdown), or just by mucking it (No reason to get involved in a marginal situation this early).

I think I generally take a passive line here in the early levels, especially after the flop call, and if that means giving someone a free draw to their flush, so be it.

I think if you're going to play this aggressively, you need to control the size of the pot. The way you've played it, you've put yourself in a position where you can't even make a non-fishy blocking bet on this river.

Were I to play this aggressively, I think I raise the flop to 60, then bet the turn for about 100 or so. This would give you some breathing room on the river to bet out and fold to a raise.

I also think a very good argument could be made just for calling the 15 on the flop and mucking to any aggression.
