I think its a good time for me to share my thoughts on the hand. I don't assume my thought process to be 100% correct, I may have missed some possible combinations along the way (and if so please feel free to post it in this thread so I can revise the calcs) but I thought I'd share it with you all because it doesn't seem to match what some of your assumptions are. I spent two hours combing over the calculations in this hand, hope I didnt make any mistakes! Get read for a long post, hope its not too tl/dr for ya ;-)
3rd street: Hero’s equity edge is so small vs any 2 random down cards that its best to just call the completion on 3rd, raising just inflates the pot and in fact may reduce fold equity on future streets when hero needs it most due to pot size.

4th street (5sb): As discussed in the OP, it’s the Hero’s read that villain’s strongest “hold’em range†hands will exhibit more action on 3rd, since villain didn’t re-raise on 3rd I think we can remove JJ-KK from this range. I chose to keep AA in the range for balance because the villain might choose to slowplay this hand or KK so we include 4 combinations out of the possible 8 of AA-KK combined. This means I expect more action from overcards that connect well with this board, as well as pairs 55-KK on 4th. Hero is likely behind, but has enough pot equity to continue, his equity share of the pot is 3.2sb after calling. NOTE – in a tough HU match hero can might expect to be c/r’ed on this board vs. some opponents with absolute air – if that is the case then villain still has a small equity edge assuming one small and one middle card in the hole, hero only gets the equity edge if two non-paired cards 6 or less are in the hole)
RANGE: 55-QQ, AA, 53, 78, 89, TJ, JQ, 8J | 9c Ts (53 was included to add balance to range for possible air from a tough player)

5th Street (4.5BB): When hero is raised we can greatly reduce villain’s range, villain now knows he is up against sixes up at a minimum, therefore he isn’t going to be raising at the bottom end of his range unless he thinks he can buy a free card in position on 6th – a high variance proposition considering Hero’s likely range of 2 pair. RANGE A below shows the tigher end of villain’s range, RANGE B includes the possibility of a raise for a free card. Without a prior read I would chose to follow RANGE A and therefore fold, I need prior evidence to go with RANGE B.
RANGE A: 55, 9T, 95, T5, TT | 9c Ts 5h – Hero has 18% equity, and should therefore fold

RANGE B: 55, 9T, 95, T5, TT, 78, JQ, 8J | 9c Ts 5h – Hero has 45% equity and therefore can continue to play on

We will be using RANGE B from this point forward since hero chose to call.
6th Street (8.5BB): This is one of the worst cards hero could see but the pot is so huge that folding would be incorrect. The pot is laying 9.5:1, hero’s equity share is 2.52BB – its thin, but a call is absolutely correct in the long run. I don’t think the action on this street changes the prior range, therefore we continue with RANGE B unchanged

7th Street (10.5BB): I tried running this street through ProPokerTools but I keep getting an error that says “Failed Could not compute any results. Simulation is either impossible or impractical to completeâ€, ironic because that error statement kind of sums up 7th street for the hero. It’s my assumption that villain knows that If Hero raises the river with a board of 3s 6d 6h 7c – he always has a boat, there are no other hands within hero’s range that he could possibly have that is logical, trip sixes is impossible because hero would have folded with naked 66 earlier in the hand. Hero’s hand is practically exposed when he raises, villain’s 3-bet almost ALWAYS crushes hero’s range. I know this goes contrary to what has been previously assumed in this thread, but I really do believe the hero is crushed close to 93% of the time. Since a call shows a positive EV of .085 BB calling is just barely correct –4-betting is pure suicide in my eyes.
To wrap things up, if I were the hero I would -
1) call on 3rd instead of raise
2) fold on 5th
3) call a 3-bet on the river.If the pot were 2BB smaller I would fold to the 3-bet.
For what it's worth, when the hero first told me the hand I said raise, call a 5bet on 7th, but once I saw it all on paper I realized how precise villain would see hero's hand and therefore putting any more raises into the pot was spewing.
Opinions? I hope to get some rebuttal, I admit that the optimal play in this hand is highly subjective
