"IMO, the preflop raise and flop raise were automatic."


I myself, am finding more and more situations (on the flop) where automatic raises are not all that automatic and I think this might be one. If your opponent flopped a legitimate flush draw, your raise won't necessarily accomplish much. If he's really good and tricky, it might even create further problems. Does it matter whether you charge him to draw or he charges himself? If a heart does fall, you might be glad you didn't raise the flop. Of course, I'm assuming any heart he deems worthy to semi-bluff with. he'll take to the river if he hits.
