We just made the final table of a $1 45-man on Stars. I had the #2 stack and was in the SB for this hand. I knew BB from the other table and he was a very tight player. He was on my right and wouldn't even challenge my BB when everyone folded to him. If he raised, I would fold because he probably had a hand. I was also picking off lots of steals. Bagonirix was watching and even he told me to stop stealing.
I have no clue about MP3. This was the 4th hand after we made FT so not enough information to make any opinion about MP3 as I never shared a table with her (Assume it's a her because of a feminine name.)

4 folds, MP3 calls t600, 2 folds, Hero ________??????

Here are my choices...
A. Fold (No information about MP3)
B. Call (Same reason plus it lets BB in for free)
C. Raise to 1800 (Probably gonna get BB to fold, but MP3 will probably call)
D. Raise to 3000 (Same as above, but chances of MP3 folding enhanced)
E. Push (Greatest chance of MP3 folding, but also greatest chance of losing too many chips)

After I get a few responses, I'll let y'all know what happened.

I don't know anything about tournaments, but. I say go w/ C.

why? no idea. I am just spitballin here.

Because you're OOP, nothing wrong with folding this. Stacks are too short to be aggressive without committing a large portion of your stack that you don't need to commit. 6-handed or less, I'd push. Here, I can dump it.

One vote for A and one vote for C. Anyone else?

Correct me if I'm wrong, but its 300 to call and there is 1500 in the pot. There's no way you fold this getting 5:1. I know we don't have a read on MP3, but is he limping with TT+ or AJ+? Maybe TT or AJ, but its very unlikely that he has us dominated. He probably has a weak ace, small pair or suited connectors - the most likely limping hands. He could also have KJ, KT, QT. There is a chance he is being "Donkey-Tricky" with AA, but we can't assume that.

I'd be tempted to raise to isolate and take the lead going to the flop, maybe getting him to throw his hand away pf. The only problem is that making a 3BB raise and then c-betting is committing around 1/3 our stack. AT is not a hand I would want to do that with.

If we call, we are keeping the pot size reasonable. We are 1st to act after the flop, so we can take the lead there. I say call and then lead out with 800 on almost any flop. BB will fold to a bet unless he has us beat. MP3 will be hard pressed to continue without a hand.

I actually went with C and raised to 1800. I figured I was ahead of MP3's range and might get her to fold, not wanting to get involved with a marginal hand against a bigger stack. BB folded and MP3 called my raise. Flop in part 2.
