Upon reflection, I won't rule out KdQd for BB. I had it in my flop calling range (as all KQ) and with the flush draw I guess he might be tempted to call turn as well as any diamond (not ace), ten or king improves his hand.

For SB, I initially didn't like the river bet with a full house. Upon reflection I can't rule out full houses or quads because they want value (to be called) and too strong a bet can elicit folds. So with full houses in SBs range I expand that with AK, AJ, AA, KK, JJ. And since my basic thought for flop and turn was that he's betting with two pair or better, I have to also include QT - which is also consistent with the river bet. With the bet size I think he has a lot more value than bluff/semi-bluff hands in his range, but if we were to include some semi-bluff I guess they would be the AQ/AT variety or perhaps lower heart flush draws. Lower heart flush draws don't make this river bet and AQ/AT might.

Modified BB range: AQ/AT/KdQd
Modified SB range: AA/KK/JJ/AK/AJ/KJ/QT/AQ/AT
