mid pair play.

I'm not 100% sure about preflop, but I think it is fine. It possibly depends on MP, but you have so few hands on them.
Flop is fine.
Turn you should check. By donk betting you are turning your hand that has show down value into a bluff which isn't good.

Thank you for your reply!

Just want to clarify from you...

On the turn I bet 80% of the pot.

On river, i kinda donked bet 30% pot.

May i ask if u mean to check on turn or river? instead of betting.

because donk bet for me is like 1.5bb 1bb 2bb HAHAHAH

Turn: (24.5 BB, 2 players) 6
Hero bets 18.5 BB, BTN calls 18.5 BB

River: (61.5 BB, 2 players) J
Hero bets 20 BB, BTN raises to 61.5 BB and is all-in, fold

Fold pre - You almost never need to be cold calling OOP in this spot (there are a few rare and specific exceptions). BTN looks very tight and is 3betting an MP open and your hand performs very poorly against such a tight range (the 3bet % of 11.5 here is likely misleading - the rest of their stats are super tight, so it is likely they have just ran good with hands to 3bet).

Turn also is a check/fold - If he barrels again you are in bad shape.

Donk bet is just when you bet out of turn (when you were not the aggressor on previous street) not to do with the size of bet. Generally should avoid doing that.

I also fold preflop. One additional stat I keep on my HUD is fold to 3Bet. The Original Raiser is obviously a bit loose; but what do you do if OR 4bets or jams? Playing this hand (as pretty as it is) OOP is a losing propisiton imho.

Yes stop cold calling 3b oop.

Another concept is the wawb... way ahead (or) way behind. You essentially want to get to showdown as cheaply as possible. If he is scared that you have an ace with his TT you'll know it and you'll scoop after all said and done.

Also regarding the "donk" bet. It was coined because donks bet for information. Here we should be checking for information.

i rarely donk unless im at the big blind, which explains why I lose so much on S/D on that position. need to open tighter, it has improved now.

So instead of betting 80% OTT, better to check for info? In what situation do u bet and what situation do u check?

Side qn:
Is betting 80% pot OOP considering donking too?

Yes i am aware that the 3bet from the BTN (low vpip and low3!) meaning is super tight and when he 3bets is even super super monster tight hands

probably AA,KK and stuff. On that hand i am already thinking about these hands. Hence i didnt 4bet or jam.

Somehow i was thinking to call to see flop due to flush and broadway potential.

Usually they would fold and be tight postflop if lets say his AK doesnt hit or any of their NON pocket monster hands hit. In this case, when he calls means he got something to show. When he called that turn i already knew. So donking 30% pot on the river is just throwing money away lol

Unfortunately the cards didnt hit any flush nor broadway. Hence i let this go

No donking is leading oop after you called on a previous street. There are times when it's appropriate. Basically on boards that favor capped ranges that get checked through a lot. 0

Fold pre cold calling 3bets is generally bad and your hand functions poorly as a bluff or raise

@OP,

For now simply do not cold call 3-bets. Cold calling a 3-bet would be where there is an RFI and a 3-bet and you are not the player RFI-ing and you call (as in this example where you are in the BB). If you are in this situation simply 4-bet or fold. If you think it is close between 4-betting or folding, then simply fold. This will simplify your strategy while not giving up any significant amount of EV. This also means you are going to go into more pots as the aggressor (4-bet) which is going to result in easier to follow ranges and strategies in both the preflop and postflop nodes.

Appreciate the advice sir!

Thanks everyone for sharing what it means on Donk Bet (nothing to do with size and its just betting OOP where previous street I was not the aggressor) and not to cold call 3bet OOP Either raise or fold.

Great insights!

"which is going to result in easier to follow ranges and strategies in both the preflop and postflop nodes."

Meaning the range gets polarized and get to heads up?

Your range would be linear as the cold 4-bettor.
