What does villain know about your turn betting frequency? How bluffy is he?
If you're double barreling with air at a significantly lower rate than you're c-betting, this is a bet/fold on the turn, especially on a dry board like this with no draws in villain's range (this turn decision becomes a lot different on a board like K
8
6
9
, for example.) You might have a bet sizing tell here too. If the guy is truly a good player, he'll likely interpret the 1/2PSB as either a bluff or a one pair hand. How much would you bet with 99 or 77 here? I'd go at least 85-90 OTT with all of my value range.
With that said, good fold on the river. I understand being paranoid about competent people playing back at you, but people generally aren't bluffing as much as you think they are (I've been there before...I have a lot of experience with failed bluff catching on the river
)
Finally, my first rule of seat selection is to NEVER have a tough player in any of the three seats to my left.
