I might just be overthinking this.

you are way overthinking this.

wtf (I agree)..

You seem to think the only hands efficacy can limp are low pocket pairs.

At least bet/call then....

Cause if he were smart he'd be b3b a FH anyway.. unless he thought you were a pansy or something

You are overthinking this. Sure he's got 22-55 a lot of times when he overlimps preflop, but I think he would be stupid to check the river OOP with a boat when he's likely to get raised by a flush or straight, in which case he can 3-bet. So, I just bet-call and laugh if he shows up with a boat because he saved me a bet.

I'd raise this flop because my hand is so strong that people are making a big mistake cold-calling 2 bets. And, when they coldcall 2 bets it's usually with a hand like Ax that will check-raise if the 3 hits. So, I'm basically raising this flop to set up a potential 3-bet on an expensive street, while also taking initiative that could help me take this down UI on the turn or river.

First off, I am a pansy.
Second, wtf you guys are raising this river if he leads? There's no way I would even think about raising...every draw just got there and he's still leading??

No, I'm not saying he has me beat every time here. I'm saying that my hand is pretty much face up here and I don't think he is paying off basically anything that I have beat except like 66, Axs. And I get owned when he has a boat or bigger flush.

Finally, if you bet this river and get checkraised, am I really good enough to call?

lol

super easy bet/call here

It if is any other spade that pairs the board on the river than I disagree with the notion that its an easy bet/call. I still dont think its easy here. Its definitely a bet and probably a call, but Efficacy is never raising this river with less than an 8 high flush.

Honestly after going over hand ranges for both of you guys, you have a little more to worry about than I initially suspected....

Mostly because I suspect effeciacy will likely fold any pair here, so I think the majority of times he's c/f this river.

However, there are hands like A3 in his range, that he may be c/cing, reading you for a 6 or a flush draw.

I think so many people would raise this river with a 6 or a flush, that he would try a b3b the majority of the time... But maybe he thinks you are as nitty as you claim to be, in which case a c/r is often better.

(unless of course you are so unbelievably nitty that you check a flush here, which case he should bet)

A good way to balance this would be to check 6x, and bet/call a flush.. This makes him close to indifferenet between betting and check/raising.

Nit level wars!

PS raise flop

OK well I guess I was overthinking this. Or just being results oriented. I bet/folded and felt like a ******.

I wouldnt feel that bad about it. Honestly Efficacy would have to be out of line to raise this river with less than a flush. Not saying it isnt possible, but it is unlikely.
