re: Poker & $10 NLHE 6-max: Aq 3bet Tptk
I see this problem a lot with players when you don't have a plan going into the turn.
If you're going to barrel the flop, check raising the turn makes very little sense. Because if you had a huge hand, you would have check/called the flop unless you are the master trapper (explain later) . When you make decisions for the future, think about the story you're telling.
You 3-bet pre from the small with AQ suited to start. Personally I would call here, as this is a hand you always want to see a flop with. Against MP range I understand the 3-bet, but if you get 4-bet you're folding 100% of the time, and why make this hand stronger, or weaker, then it is. But you 3-bet and get two calls, so lets go to the flop.
Flop is Q38 two diamonds, I relatively good flop for you since its not super connected and you had TPTK. When you bet here into 3 players from the SB, my question to you is "What do you find out with this bet?" If someone calls or raises, you have no idea where you're at. A ton of hands have a ton of equity going into the turn, especially when like 95% of your range should check the flop. I'd rather check/call or check/raise and probably check raise, because I want one of these players out of here, but you bet and get two calls and now we go to the turn.
Turn is a blank and you check. If I'm the villian, I'm going "Huh?" Like that awkward dog head tilt when he doesnt know whats going on. This story doesnt make sense and now you have no clue where you are in this hand. If you're going to check, you need to raise a bet on the turn ALL the time, because you can be dead, and you can be behind, but you have no clue now and are guessing. This is why I said earlier it makes little sense because what your range should be doing a lot of the time on the flop to isolate, but you have to do it given the route we took, which just leads to problems.
Now the river you lead out after check/calling the turn on a little scary card, a J. QJ got there, 109 of diamonds got there, two jacks can take this line and got there, you lose to 88, and 33, but you dont know. Its all a guess. At this point I'd check call, but I'd hate it, because its a complete 50/50.
Next time just take a more balanced line, or a story that makes more sense. You may have won the hand as I think he has KQ, as a set probably value/raises the river. But next time, take a line thats going to earn you more money in the long run, take down pots so people dont catch up, and so you can figure out where you are and polarize ranges better so you can put people on a hand.
