What to do in spots like this? Folding TPTK to a minraise on flop is ultra weaktight, but when he bets a blank turn, I just don't feel that I'm ever good here, especially considering how my perceived range from UTG smashes that flop (it's very likely I have premiums like AK/QQ+). Even though he's repping very thin (like only ever 77 and maybe QQ and AK spades), I just don't see how I can continue past the turn with a heavily RIO type hand with ~180BB effective stacks starting the hand.

So basically, what goes through your mind on flop and what's your plan on turn (for blanks) if you call and he bets again? Is calling the flop minraise but folding to a turn bet spew? See this thread for a similar situation (except hero is IP instead): http://forumserver.twoplustwo.com/78...m-fish-868391/ - I think the majority of the comments said bet/calling flop but folding to a turn bet is okay if villain's range is more weighted towards value if he fires turn again after getting called on flop, so is that the case here?

Cheers.

I like to 3-Bet and get it in on these flops vs. most non-nits. Otherwise, your line seems fine.
Rush + unknown = I could find a fold on the flop min-raise.

i think calling min raise flop is ok, you have some outs, but with the intention that if you dont improve on the turn, you have to fold, so yes, its spewy in a way getting 4,5:1 with max 5 outs.
btw i see players flatting 77+ from BTN every day...

That's definitely the case. I see a lot of people, especially bad regs, raising the flop as a bluff and then shut down. If they barrel 2 times or 3 times I need history with them or sick reads to make hero calls. I think this is played fine as long as we're talking 2nl-10nl
