In my local £1/2 we have

in the small blind.A winning reg who is on a big downswing/has taken a break from playing opens to 15. He has been tighter than normal tonight and is desperate not to spew/make poor postflop plays. We are friends so he knows I know all this.
Reg opens to £15. I peel, recreational player peels.
Flop

Rec donks for £13. Reg makes it £44.
Rec has a range of Ax hands (weak ones), some like KQ hands maybe some flush draws/straight draws but he would mostly c/c these. Reg understands this.
Rec has £85 back and is a bit steamy/tilted.
Reg has ~340 at start of the hand.
I don't know if he thinks I flat AQ/AJ/JJ pre, he does know i 3b/4b more than any other reg. I'd give myself a pretty low 3b% in this spot although I'm not sure he knows that. As an aside guy between me and rec is a weaker player as well, playing £150. Rec isn't a big squeezer pre.
