I think your line is fine tbh.

I'm surprised they checked the flop since this is such a standard rangebet for the 4bettor.

The turn probe looks natural with this hand. I prefer the probe over the XR, XC or XF with this gutshot.

Give up on the brick river. You block the very hands you're trying to fold out with a bluff, namely JJ and QQ.

I would fold pre, firstly people not 4bet bluffing enough (not only my opinion, chaps said same and one more guy :D); 2nd Rake for nl200 is high!!! Thats what GTO wizard defends and it is bit loose for what I've seen. I know solutions for 500z where 88-66 folding more and AQo ~75% folds as well.

Flop either he trapping or doesnt know how to play here. Both possible

Turn I would just give up, at this node likely you just checking close to 80% of your range again. Hand is good 1 street bluff only, so feels fine to stab river and balance it with KJ/KT for value

Yeah I would also fold preflop. Not crazy about the turn bet either, this is a flop that hits the 4bettor extremely well and even when he checks, I would expect to be up against a very strong range that we can't bet a lot against. A strategy that just cbets everything and occasionally checks some KK/QQ type of things is not that uncommon either.

Wow I came to the forums for the first time looking for help with a specific question and this conversation is about exactly that. I play .25/.50 and some .50/1 online and I have access to GTO+, but no preflop solutions for 4bet calls. I won't ask people to post a bunch of graphs or anything, but I have a few burning questions about 4bet call ranges.

The only hands I feel certain I'm calling correctly with are AQs, TT and JJ. I'm wondering if vs weaker fields, are people letting go of 99 a lot from positions tighter than sb vs bb? AJs? Are you mixing some folds with TT vs some weaker, tighter players? Let me know if you have any guidance on that.

Thanks.
