Player is on most of our tables, we hardly ever notice them, quite a weak / passive player.
We have

UTG (50nl), £1.5. Button and BB call. Don't really know button, regy to some extent.
Flop;

BB CHeck, We bet£3.56, call call.
Turn:

BB Check, we bet £11.57. Button Call, BB raises to £30.64, We call, button calls.
Pot is £107. We have £97 behind. BB has 70, button has £92.
River

.
Button Jams, we fold, button folds.
I felt like it was a decent fold at the time, especially with the button still in the hand.
Both players were on the tight side.
I wonder why they check raised the turn though, if they had 77.
I suppose it could be JJ that they hav'nt 3 bet pre. But i'd expect them to 3 bet JJ??
Dunno, if it could be an overplayed JQ.
It's one of those ones, just feels like I was beat given this particular player. But feels a bit dirty foldin here!
