Need help with some hands

[Rick Diesel]

Hand #1:

Stars $109 last night. 260 runners, 27 places pay. As always, real cash in top 5 spots. 47 players left, average stack is 8,300. Blinds are 200/400 w/25 ante.

I have about 7,800 in MP. I get A [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/spade.gif[/img]. I have not stolen the blinds in a while, so this feels like the right time. I make it 1,200 to go. It is folded to the SB who calls. The SB has me covered with about 11,000. The BB folds.

The flop comes 8 [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/club.gif[/img]3 [img]/images/graemlins/club.gif[/img].

The SB min bets 400. I raise it to 2,400. The SB makes it 4,000 more. I now have 4,200 chips left. What is my play here?

Hand #2

Stars $11 rebuy last night. I have built a huge stack of about 60,000. Average is 24,000. Blinds are at 300/600 w/50 ante. Started with 920 players, down to 145, pays 81 spots but I am eyeing the top 5.

MP with about 18,000 limps in. Folds to SB who calls. I am in the BB with A [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/spade.gif[/img] and check.

The flop comes A [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/club.gif[/img].

SB checks, I check, MP bets out 1,200. SB calls. I raise it 3,600 more. MP min-raises 3,600 on top of that. SB folds.

I now have about 55,000 left and MP has about 10,000 left. What's my play?

Hand #3

Stars $11 rebuy Tuesday night. Pays 81 spots, with 115 players left. Average is 30,000 and I have 8,200 after a terrible beat. Blinds are 1,000/2,000 w/100 ante.

MP with big stack makes it 12,000 to go. Folded to me on the button with A [img]/images/graemlins/heart.gif[/img]J [img]/images/graemlins/spade.gif[/img]. SB and BB are both SUPER tight, and they will fold any hands that are not AA or KK. Do I call all-in or fold and look for a spot to get the money in first?

Thanks in advance for any analysis.
