Preflop was good, But post flop was not what I would have done.
I look at it like this, depending on stacks, a middle position limper is usually going to have a medium to weak ace. The preflop play should have pushed the limper out.
The fact that he didn't go out means either he is a donk or has a hand.
So this is where it gets weird, being out of position with cowboys against a flopped ace, I would have put in a probe bet on the flop instead of just checking. This could also be viewed as a C-bet. Something in the range of 3/4 to full pot would be reasonable.
If MP calls, then I know he has the ace, possible made two pair, and I know I can check fold the turn should nothing come out in my favor.
Sometimes one has to learn to lay down the big pocket pair. It's a tough call to do it, but when you think about it objectively and reasonably assume you're beaten, then those fish hooks, ladies, cowboays, or aces even, can and should be folded.
Is folding JKo UTG+1 too nitty?
Some info about the Villain would be nice here to assign him a more precise range. Some regs pretty much only have a small or medium pocket pair, when they limp behind, but fish love to limp-call crappy aces. As Evan Jarvis say, make your decision on the turn, when you have a hand with little chance of improving. Without info I typically prefer to give people credit for having it rather than for being able to bluff.
This is Way Ahead/Way Behind, meaning you're either killing him or not likely to catch up. Much easier to play in position, but the objective is to get to the river with as small a pot as possible since, if readless, you just don't know.
In position I check flop to eliminate one street. Out of position, I maybe bet the flop and check turn, maybe folding to a turn bet but it depends on how I've been seen as well. Reads are pretty crucial here.
There is a misfire with everyone. For some, throwing such a big pocket pair off is a problem. Notes on players are not always suitable in all situations. What is happening at the table needs to be monitored more.
