he looks like a huge station at 50/10/.6 I think you get enough value out of naked flush draws and Ac5x etc here to bet pot/shove him in. You have a flush draw and an open ender to bail you out too when he shows up with something like KT also, or even a set, so I like slightly overbetting and pushing passive short stacks in in these spots.
Give it up, you played it fine. I think people care a bit too much about shortstacks. If he had 100BB you wouldn't put more money in, right? And I don't see any reason to put anymore money in here either (unless he had like $3 left or something). He won't bluff with those stats, so check it out.
Bet. His hand probably hasn't improved much by turn. If you're going to bet flop (which I would have too), have to bet turn that doesn't look to have improved his hand much. You have position, and a hand with sd value, imo., with room to improve...and he hasn't shown strength at any point.
I just go all in. Sometimes you'll get schooled by QT, but he has A, straight draws and smaller pairs a lot too, and they will all call the turn if they called the flop. Shortstackers are not known for folding the turn.
Against a reasonable players range a turn shove looks pretty bad, but we have no expectation of this given the 50/10/.6 and the short stack. Like others have said he will be calling you with such a wide range of hands you have to shove. Even if he happens to have a T or 2pr or something, you still have outs. Youre only dead to made flush but it seems unreasonable to assume this player has one. I would stick it in and feel good about it.
