OK. So I recently saw a hand as follows. I was not in the hand so I will not be hero or villain. I'm looking for other peoples opinions on it and the idea's the player held.

5/10 NL live cash game 9 seats with a $20 straddle

Player 1 posts the SB - $5
Player 2 posts the BB - $10
Player 3 posts the straddle - $20
Player 4 calls - $20
Player 5 folds
Player 6 calls - $20
Player 7 calls - $20
Villain raises (cut-off) - $100
Hero raises (Button) - $300
Folds around to villain who calls $300

Pot is now $695

Something's to note here. Villain is loose. Basically a fish. Will call down with weak holdings of bottom or middle pairs and also lead out with weak holdings. Hero is tight aggressive.

***FLOP*** [Jc8h5d]

Villain checks
Hero bets - $475
Villain calls - $475

***TURN*** [Jc8h5d] [7d]

Villain checks
Hero checks

***RIVER*** [Jc8h5d] [7d] [9d]

Villain checks
Hero bets all in - $2000+
Villain folds

Hero collects $1645

Villain had $1800ish with his fold on the river.

Now after the hand was complete the two talked about the hand.

Hero was heard saying he can represent his 3bet bluff range of some type of suited connector. Making either a flush or straight on the river.

My thoughts on this are as follows. Based on the action and the fact hero said he can represent his bluff range I put him on AKo, AQo that completely missed. He bets flop and checks turn then shoves river. Now creating a 3bet range for him we can put AA, KK, QQ, JJ, and maybe 1010 into his range along with AKo+ and AQo+ Possibly AJo+ but I feel the player is tighter than that. So with his line You can remove AA, KK, QQ, and JJ from his river all in bets as those are just too thin for value and likely either shove or bet turn and check river. So it leaves him with complete air hands like AQo+ and the possible bluff range he decides to mention at the end of the hand. Which based on his communication I feel is unlikely because he said and I quote "I could be representing my bluff range". Key word being "could", as if it was an after thought once the hand was played and trying to convince you of that story. Another thing I find wrong with this is that unless you've hit your bluff 3bet range you're not betting river like that. Again say you have a bluff range of suited connectors. Most of the cards that came block your bluff range. 5d6d, blocked. 7d8d, blocked. 7d6d, 8d9d, blocked. So this leaves some sort of suited gappers as his bluff range.

Then once all this is in play what is he representing on the river based on all this information. He is more likely to be 3betting with strong broadways because he is tight aggressive with possible suited connectors in his range leaning towards more combos of broadways and large PP over suited bluffs. As I believe this player bets more for value than bluffing preflop. So he has 2 combo's of AK AQ diamonds that hit second nut flush. Then what 5s6s for a straight on the river that he shoves for value.

Personally all in all I feel his range leans more to air combo's than value combo's here based on his line.

All this in consideration. Is it even worth 3bet bluffing against a fish who will call? or even putting suited connectors into a bluff range when you can call for $100 and likely get 5-1 or possibly 6-1 as the table is playing loose. The based on the cards I put the board way more in the fish's range then I ever do the hero's range. I guess too wouldn't a player who has 3bet preflop who now holds a pair and draw bet turn instead of check it back? This is what really makes me think hero had air. Any combo that hits with the six now seems pretty strong to represent the top of your 3bet range by shoving turn. Then if called still has a decent amount of equity against all calling hands save the nut straight.

I also realize that 109 and such make a straight but based on what was said the 10 doesn't fit the range and I also don't think the player 3bet bluffs with that based on what was said. Specifically 78 was mentioned as 3bet bluff range.

Thoughts?
