Hey guys,

I think i missplayed that hand pretty hard.
Villain seemed to be a TAG. He always raised the BU 4times the BB, and I either folded or 3bettet but rarely called. In 3bet Pots, he folded pretty often to my Cbets, so I decided to go ahead and Cbet. Turn helps me and I'm not too worried about Draws, so I tried to checkraise it. As he checks back I put him on a medium Pair and decide to jam it on the river hoping he doesn't believe me. I appreciate your comments!

Actually I think u like abused the hand totally.

If the guy is a TAG, hes will check back 78/98 and TT on turn for some kind of potcontrol. The only thing you will beat with a checkraise is bluffs. A TAG doesnt bluff that often i guess, and if he bluffs he won't do it hard... so it wont be profitable.

I rather check to bet river for value. If you prefere to check.

Bet should altough be a good alternative because he will often put you on a 2barrel. And then you could just checkcall river.

All hands you actually have value against on river you kill by clicking allin. He will fold 89/78 and TT. I guess you hoped he had KJ/QJ.

Correct me if i'm wrong. Im new into HU

If I understand this correctly, I'd say this is a good assessment of the hand. OP, you are just not likely to get called by worse. I don't like the check on the turn b/c there are a ton of draws that'll be happy to take a free card.

When I'm betting, I think I commit me to the pot and have to call a shove. Therefore I decided to shove, because I doubt he'll fold tp to a shove.

This reasoning would be fine if the purpose of your bet was to get better hands to fold. But it's not, so it's not.

Also if villain had TP he probably would have bet it on the turn for the same reasons you should have (i.e. board is drawey, overcards can come etc..)

As you say, if you bet and get raised you're calling (this is not a necessity- this is the river so it's not that you're committed because you have outs/equity. If you know that villain won't raise with a worse hand then there's nothing wrong with betting 1/2 pot and folding to a shove). All that means is that the times you're beat you're getting stacked whatever betsize you chose. So we can ignore the better hands part of his range when choosing betsize. So what worse hands does he have that can call any bet at all? Mid-pair + draw type hands, as CobbV pointed out. And these hands will probably fold to an overbet shove.
