I'm currently drilling XR out of the BB vs. late position opens both in theory and in GTO+. This spot came up in my session this morning.

General Dynamic: 9xx boards lead to a high XR frequency BB vs. BTN. Versus a 1/3 c-bet our XR frequency should lie somewhere around 20% of our range.

Combo Selection: I cannot XR all my BDFDs here. BDFDs with SDV (Ace high) go into my XC range, lower BDFDs into my XR range, hence the XR with J4s. This turn leads to a polarization of our betting range, hence the bigger sizing rather than block. Do we follow through OTR?
