The spot is UTG vs. BB SRP, Villain is unkown but has a full stack.

OTF: On this QTx two-tone board, equities run rather close between the BB and the PFR although it is still favorable for UTG. I definitely have a XR range out of the BB here (even more so vs. the 1/3 c-bet) and my value raises are constructed around QT, TT, 66.

AhJx is not the most obvious XR here. The job that I assign it with in my XR range is particularly to barrell on dynamic three-to-flush turn cards. If I would only XR value and FDs here, then my range consists of 100% value on hearts on OTT. Hands like AhXx provide me with bluffs here that have 9 outs to the nuts PLUS very nice card removal effects since they block all nut flush draw floats from UTG. These advantages together with the properties of having a (straight) draw to the nuts OTF and blocking UTG's continuing range (AQ, AT, AA, QJ) makes it a fine XR for me. On non-heart turns, this hand category just gives up since there is no need for the job.

Should I XR bigger?

OTT: As discussed above, I'm barelling this combo now. Since I'm betting almost my entire range here, I'm going for a small sizing.

OTR: Are we getting to showdown now? Check/call or Check/fold?
