PLO8 first session

I'm starting from the bottom up at PLO8 (have dabbled in the game before, but am a NLH player by background). I played 2-tables of PLO8 $0.01/0.02 tables today for about 45 min. I'm posting a few hands for review. Any feedback is appreciated.

#1. AA39 hand with top set on a high-draw board multiway. Thought a smooth call on flop would be better than a raise since no redraws to my hand. If turn bricked (or filled up as I did), I'd be in better shape to jam. Right thinking?

#2. AA58 hand with top set on rainbow board. Here I jammed on the flop because I thought I could get it in against one-way hands, like nut low draws or high-straight draws. Since I had current nuts and a backup low, I was hoping to play for all my chips against any one-way callers. Jam the flop, right?

#3. Another AA hand, but flopped low trips. Here I bet pot, got a caller, and then a short-stack raised pot. I re-raised with just trips trying to push the caller off figuring he would have to decide on the flop if he wanted to push all-in on a low draw or straight/flush draw on paired board. I was hoping short-stack only had a draw or weaker trips kicker. Caller folded and I split high with the short-stack (both had A5 on 55xxx board), and he took low, too. Good re-raise?

My thoughts:

#1 is OK. A lot of players prefer to push the flop immediately, which I think is your best play here. If your opponent has KQT and the flush draw, you're not much worse than a coinflip. Plenty of much weaker hands will call your raise, like pair+flush draw, gutshot+flush draw, even raw flush draws. When you know you have the best of it (given opponent's range of hands), go ahead and reraise. Otherwise you have to deal with turn scare cards scaring you off the best hand or your opponent off a weak hand he would've paid off on the flop. Check out this thread (http://forumserver.twoplustwo.com/showflat.php?Cat=&Number=3151964&page=0&view=colla psed&sb=5&o=31&fpart=1).

#2 needs to be reraised preflop. Again, at worst you're a coinflip and often way ahead of your opponent. In this scenario you were a 58/42 favorite by EV preflop. On the flop, it's time to push in. You have the nut high, which is very unlikely to be outdrawn - so generally you scoop when your opponent misses a low draw and split when he hits one.

#3 I wouldn't usually raise preflop from the small blind, and if I did it would be a big pot raise likely to thin the field considerably. On the flop, you have trips but no chance at a low. I would not commit my stack at this point. Checking and calling the flop, planning to push a high card and check/fold a low card, seems very reasonable to me.

Thanks for the feedback. A big help to have my mistakes pointed out.
