H1- I raise more preflop, .35 at least. As played, I think this is fine. I hate c/f but you can't win them all. Can't even win most of them.

H2- Your analysis is solid, and I think I just ship the river. A8-T aren't folding at these stakes, and most players aren't playing pot control w/AK here >.>

H3- I like getting it in on the flop here. There are a lot of turn cards that suck (board pairs, non-spade 6,9, or J for instance.) You're getting called by a 9 and worse flush draws quite a bit imo.
