BB is a LAG, don't have much history. He plays 41/28 with 17 overall 3bet (600h) , although not really positionally aware as he is 3betting 29% MPvsEP for instance. He skipped cbet in 3bet pot only 3 times, c/r once and c/f twice so seems to check polarized, although sample is very small.

I am considering putting this hand into my checkback range, we have very good visibility for the most part and good deception, and are not really happy getting c/r with our hand being this deep as we will have a tough time continuing (calling isn't a great option since many turncards bring possible straights. His c/f range should not have much equity at all against our hand (could potentially have some good turns, but most of those we can call.
