just got here, no reads. I think my preflop should have been to $2, which is probably the root of my problem, but besides that, can i fold here?

also as a side question, should i be buying in the max amount every time or vary that depending on other stack sizes?

Preflop, definitely make it $2 to go.

On the flop, you may want to pot this since you had 2 cold-callers. But I don't think your bet size was necessarily too small. After Button wakes up I'm shoving just as you did. MP has put dead money in the pot, but I want this heads up. Good thing for you the cards made your runner-runner straight.

As far as buy-in, you should always buy in for the max unless you have a specific reason not to. Playing with 100BB gives you an advantage over other players, because you're better than they are post-flop.

With a short-stack like that, there's not much else you can do.

Stop playing short!
