I pick up 68ss in the CO of a 6 max NL online game. Effective stack size is $100. I open to $3.5 and only the button calls. I haven't been at the table long, but haven't seen the button do anything dumb thus far.

FLOP Ts 9c 4s

I bet $6.0 and button calls.

TURN 9s ($21)

I bet $12.00, he tanks and makes it $29 to go. Your action? I think my bet sizing on the turn could be a little small. Anybody shoving this? Just calling? All comments appreciated.

What site do you play on? How good are the button/blinds?

Folding preflop is a real option.

So many better hands for you to defend and your range is super strong here so villian raising into you is really strong as well.

I'd fold the turn and feel ok about it.

without proper information on villain , you are pretty much playing this hand blind ... ( is he a fish over valuing trips , is he a nit who only raises boats here , does he like to run bluffs on scare cards , etc etc etc)
From a general strategy view , perhaps wait till you understand your opponents tendencies a bit better , till you start opening middle to lower parts of your pre flop range.
This way spots like this , you will already have a feel to what kind of ranges he will be raising your turn bet with .

In a vacuum raising isn't really an option as he shouldn't call you off with worse.
That leaves calling and check deciding /hoping he checks river or folding turn straight away.

These two options are pretty close , I think I lean towards calling turn due to pot odds and lack of info on oppanant, and probably check fold river .

Either way not a great spot to be in ev wise and could have been avoided with as mentioned an intitial tighter opening range.
