I take shots at 200NL, though I'm a bit underbankrolled for that (IMO for 6max I need about 30 buy-in, while I have a bit more than 20), but I am ready to step down a level if I have a big downswing, so probably it is ok. In the following 2 hands effective stacks were more than 200BB, and I'am not bankrolled for 400NL so I was a bit unsure about how I should play there.

FWIW it is Pacific (hi MVP), but I didn't run Pocker Tracker as I noticed recently that I play better without the stats, as I concentrate more on postflop reads and play (I don't know if anyone has similar issues).

Villian: When I sat down he had a big stack 800, I sad down in position to him and now he has lost a bit. Part of it he lost doubling me up when he had TPNK (any A kind), and I had 2 pairs with AK. He sees a lot of flops but rases rarely, calls with any piece of board, and fires big bets when hits. Though sometimes tries to bluff also with big bets. So it is a bit tricky to put him on a hand as gutshot is good enough for him.

Hand1. I have in BB (I have 450).
Relevant stacks MP (400), SB = Villian (450).

Preflop: MP limps, Villian completes, I raise to 10, both call.
Flop (pot 30):
checked around.
Turn (pot 30):
Villian checks, I bet 20 (I figure that I likely have the best hand here, or I have outs against Villian range)
MP minraises to 40, Villian calls,
I?

MP is for sure has me beat, but the pot odds are unreal + there are implied odds, as I am sure that MP will pay a bet of about 100 if a Jack hits, and Villian also can bet or call some. What I didn't like there is 2 flush draws (if board were rainbow I call 100% to chase my gutshot to nuts), so jacks of spade and hearts are not clear outs.

Thoughts?

Hand2.

I have AA in MP (stack 450).
UTG limps, Villian (stack 560) limps, I make it 10, folded to SB who calls (stack 50),
folded to Villian , who minraises...

Here I was unsure what to do, it seems that Villian has a pocket pair, so I shoud reraise but how much? SB will likely go AI improving pot odds for Villian.
Thoughts? (Take into account that I'm not bankrolled for 400NL).

Hand 1 I fold. Who wants to chase 2 outs on a short BR? If the flush card J comes then YOU end up with reverse implied odds and.. well.. just don't bother, because you probably have to call a bet if the A or K falls too.

Hand 2, I delay slightly, then flat call, hoping for the short stack to re-open the betting with a push, opponent #2 probably then re-raises you and you push.

or... short flat calls, you take the flop still as a huge favorite with position , on the flop you don't give a toss what the short stack does, you are looking to stack off the other guy, hopefully he has TT-KK and the flop comes rags.

Hand 1) Fold. That's too expense to draw to a gutshot, and you have a problem if the flush hits and you hit your straight, and will you honestly be able to fold to a 1/2 pot sized value bet if the river is say an A? Ugh.

Hand 2) I'm reraising for sure.
