Sounds really simple. Of course you should fold once you know you are significantly behind in a hand and someone is betting a decent amount at you right? I think a lot of us at WNP find ourselves in a situation (usually on the turn) where they pretty much have to be beaten, but call anyway, then fold the river.
I offer an example: It is WNP, midway through the session. All the players left have about have about 1.5 buy-ins or about 360 in chips. You are in MP and pick up the 6c7c. There is a modest raise ahead of you to 6, and you call along with 3 other players. There is a new player at the table that is a combination of Steven and Martin named Marven. He is tight and plays straight forward poker.
7s 7h Kd
Lovely, you have flopped trips on a safe board and you feel like you have the best hand for sure. Marven is ahead of you and leads at the pot for 15. You put him on a good K like KQ or something similar, and decide to raise to build the pot. You make it 45 to go. It folds around to Marven who smooth calls. There is now ~110 in the pot, and you both have 300 behind.
Now action is to Marven who bets 100, slightly less than pot sized, into you. This is where things get interesting.
You are at a decision point here, where you need to decide if you hand is best, and you need to decide now. When you look at the range of hands Marven could bet with here, it's very limited. Your original read was a strong K, but now it doesn't seem likely as Marven never goes broke with one pair on a paired board. You can't really put him on KK or AA or really any big pairs, and he wouldn't bet an underpair with an over card and a paired board out there. ALL signs are pointing firmly towards he has a 7. There are just no realistic hands that you are ahead of.
Yet you call.
Now the river comes the Jh, and he ships his last ~200 on the river. If you call, it's a crying call at best and you fully expect him to table a better 7 or a even a boat.
This brings me to my point: should we be folding this turn in this spot against Marven? I don't know how many times I have seen (and done myself) this situation. You have a really strong hand (this also happens with flushes and two pairs a lot), but you just can't help but call that turn bet of 100. Then the river bet comes and we can lay it down. I think a lot of us at WNP are good enough to lay down the hand on the river, because now we have figured out that we are beaten for sure and have to save that last bet.
But not that many (none) of us are laying this down on the turn.
So my question is: Should we be laying this down on the turn? All the signs point to the fact that we are beaten, and right there we should get out of the way and save the turn and river bets, right?
