I have found myself in several situations recently where I give an unknown credit when I have a suspicion that they're getting way out of line and it's really starting to frustrate me. Here's an example from last night in a 1/2 game.

There are 2 villains in this hand, both are to my direct left. I'm the big blind with a stack of roughly 300, UTG has 100, UTG+1 has us both covered.

UTG just sat down but I've seen him play before and he is absolutely terrible. He calls down light, pre and post flop and I've seen him run ridiculous 3 barrel bluffs. However, I've never seen the type of forthcoming preflop action from him.

UTG+1 sat down a few hands ago, he's an older asian who bought in for the max, has raised or limp called in every hand and has been betting large and raising.

UTG raises to 10, UTG+1 reraises to 25, folds to me and I look down at AcKc. I hate this spot, because I know I'm ahead of UTG and suspect UTG+ 1 is getting out of line, but what kind of maniac 3 bets an unknown utg raiser?

I've also seen several people, unknowns and players who have no history of getting out of line that randomly run large bluffs in spots where they have no equity or reason to make the play. Should I even worry about these situations or try to pick them off?

A maniac in your position? You already said he's terrible. Unless you think his UTG PFR is KK+, you're at worst at a coin flip. Plus there's that UTG+1 dead money in the pot. 3-bet away?

There has already been a 3 bet once action gets to me. It went raise, cold 3 bet.

Then make the determination you're not gonna let it get to you. UTG+1 is the unknown variable here. Just because you saw him open every hand so far means nothing. He could be getting a run of playable cards here.

I'd rather give them credit than cash. I'd fold here if it were me. There will always be spots to get 'em later, after you have a better line on the unknown's play. Those opportunities won't be there if you step in it early and get stacked now.

Would be incline to 4 bet here. Maybe to 55-65 range. A few things can happen here
• You most likey have the best hand= bet for value
• V1 shoves/calls with worst V2 reshoves = fold as you are probably behind
• V1 shoves V2 calls= Squeeze to get some dead money
• V1 & V2 just call = evaluate flop and play some poker
I just dont think calling the 3 bet is a good idea given that you dont have a read on V2.
You do have postion but still you need to hit the flop or just playing in the dark against the unknown.
What happens if you just call and miss the flop and V2 c bets on a 9 high flop.
V2 sounds like the guy that will cbet most flops and that will make him to blow you off your hand when you could still be winning with Ace high

You know the UTG and you've never seen him raise from that position? Easy fold.

Should have been more clear. I've never seen the overall preflop action, including information that happens after my move. He raises a lot from all positions. He isn't positionally aware.
