this hand was vs a presumed fish whom I didn't have many hands on but seemed to be on the tighter side. i'm pretty much at the top of my range here- I don't have QQ/TT/55 ever. sometimes have 44 but would almost always raise the turn with it if I floated with the 4 of spades and binked it on the turn. I don't defend Q5o/Q4o. Q5s I would sometimes have in my range, perhaps 50% of the time. and Q4s I would never raise the flop or turn so I have 100% of the time.

the question is-1 is he ever bluffing??
and 2- is he jamming worse for value??

1-in my opinion its extremely unlikely he is bluffing unless he turn a hand such as KQ in to a bluff- putting me on Q4/44 of course and knowing he doesn't beat any value but blocks top boat and unblocks 44 which can basically never ever call vs the jam. so actually bluffing KQ makes quite a lot of sense here in my opinion. but again, I believe he was a rec so he may never do this.

2- not sure but maybe?? if he's a rec he might think I'm raising a Q here like QJ on the river and jam TT/55 or maybe even AQ. again, unlikely but certainly a possibility.

would like to hear some people's opinions, especially those who play 500z or perhaps even higher. cheers.
