Crazy river play



The game is 6 handed Zoom at Pokerstars with 0.5-$1. Villain (have raised 12% of the 50 hands we played, seems like a regular based on limited stats) has $167 in the beginning of the hand and I have a bit over $200. Villain raised to $3 from UTG+1 and I call with JdJc from UTG+2. Everyone else folded.


Flop (Heads up pot $7.50) 2h7cJh: Villain bet 5, I raised to $13, Villain calls after some hesitation.
Turn (pot 33.50) Qc: Villain check, I bet $16, Villain calls
At this point I put villain on a range of Ax (heart),  KhQh, Th9h, AA, KK, 77, 22
Also, I figure that villain puts me on a polarized ranged consisting of monster and flush draws.
(Based on this I exclude 80% of QQ since I assume he would raise here most of the time)
River (pot 65.50) Ah Villain check without hesitation
Decision 1: Check or bet. The safest play is check since he has a lot of flush draws and AA in his range. If it was any other heart I would check behind 100% of the time. The A of heart does two things, it completes some of his hands while removing most of the possible flush draws from his and my range (seen from his eyes).  His quick also suggest that he has few flush draws in his range. A of heart is the scariest card in the deck at a first glance, and surely villain would at least consider to bet with a large percentage of his flushes. 
So how much should I bet? My thought at the point was that an allin would only get called with a flush (since he would assume that I would bet big with flushes and some complete bluffs). A small bet ½ pot could easily be called by lower sets, possible two pairs or potentially KhKx. The last hand is particular interesting since it holds a key card the King of heart. If he has that, he would know that the only flush card I can have is Th9h (1  combo) and the A of heart should stop me from betting, also hands like AJ should check here. I thought that some KK, at least if he has king of heart would result in a call. The only offset is that he might have AA. Again, I think AA would consider betting on flop  assuming I will check behind non flushes and bet flushes. In the end I think he would bet here with AA about 50% and check call 50%. At any rate, I think he would consider his option before checking.
I felt that I had a slight +EV in betting and decided to bet $31.
To my big surprise, villain moves all-in for $135 total
Basically, now I have to call 104 to win 335. I need 30% equity to justify calling
At this point all I have is a bluff catcher. Villain has three possible ranges
Value range: Flushes (set of aces and queens are extremely unlikely)
Pure bluffs: Almost possible
KK turn to bluff: KhKx seems like an excellent bluff card.
Let assume that villain knows that:
1.       Player with a set when checked to would check back 75% of the time, and call a small bet (30% of pot).
2.       Ace of heart removes many of the flush draws from my range
3.       With any of the flush draws villain has he should feel confident to bet and reluctant to check the river. Also, with AA he should consider to bet. If he checks he would lose one bet to any flush, and miss out on a bet against lower set that tends to check behind. Even if AA does check this river a lot, I expect him to take a few seconds to consider his option. With lower sets, and two pairs he would check. This was the reasoning I used to bet.
Now let assume that villain knows that I assume this!
Now, I lose to AA, QQ and flush (KT for straight as well but that is too unlikely).
His value range is KhQh,  Th9h and possible AA (but very unlikely)
His bluff range extremely narrow I would say KhKx, since Kh excludes most of my flushes and most importantly excludes the nut flush. It only leaves Th9h as the only possible flush draw I could have (given the action in the hand)
This is what I considered at this point
1.       Why did he initially check?
No hesitation check, check raises are normally abit slower. I think he was scared of the flush, but the size of my riverbet changed his mind.
2.       Which had does he expect me to bet and check with after his check.
Bet with flushes and possibly AA. Mostly check with weaker hands
3.       If I had a flush how much does he expect me to bet?
Bet big to get called by AA (since Ah takes away most of my flushes if he has a set of AA he would call)
4.       What does he think that I have?
Set
5.       Did he initially expect me to bet with a set?
No, the bet size changed his mind
6.       If he bets first to act does he expect me to call with a set?
Sometimes, plus I might have a flush (in his mind)
7.       What does he expect me to do when he raised allin?
Fold
8.       If he check raise the river with his value range what would his bet size be?
Varies, quite often small raises since sets often folds
I felt that he checked for two reasons. He assumed I would bet big with flushes and check back other hands. Hence, he beats my bluffs without risking anything and does not lose anything when beat. My small bet surprised him.  

When I bet, he realized that I had a set and saw his change. If I had a pure bluff or flush most likely I would have bet more. The more I thought about it KhKx seemed like the LEAST UNLIKELY hand. I called with 5 second left of my time bank (close to 2 minutes) got ready to “puke”, but was relieved to see that I was right.

Review:
River bet I felt sure that he could only have Th9h, 77 or KK, and felt like I was doing the right thing. After spending hours using stats program calculating ranges and different outcome I think it is marginally correct. It does however increase variation, and losing a big pot when you could check behind can be a tilt factor. So overall checking might be better. When I bet, I felt that a reraise bluff was virtually impossible and I almost instant folded. My initial hesitation was more of disgust. That hesitation was enough to get me to calm down and start analyzing the hand. After having a few days to analyze the hand, I think I made a great call. As crazy at it seems, I think a check raise allin with KhKx is more than 30% of the range (actually I think it is close 60%) making it +EV call.
Finally, I love his river play. Im sure he didn’t plan to check raise. He expected me to check as well. My bet size gave him enough info to make this high level play. Unfortunately for him, I was able to re-evaluate and made high level call. That was poker is about, thinking one level higher than your opponent and reevaluate every decision.
