So you have good equity.

If i had to take a stab, he probably has some sort of made hand which can't really improve, i.e. QQ the other 2 JJ's etc…… It's a really big overbet though, i wouldn't hate a fold here. When you think of all the cards you have to fade on the Turn/River that scare you…. etc i.e. all the Ace's King's Queen's etc diamonds.

i fold here and feel fine about it.  too marginal spot against what most likely is a combo draw, 2 overs + draw, or overpair. 16/8 over 25 hands isn't good enough for me to think he can do this after opening utg with top pair. and he 3x'd pre.  peace it

The idea and fear of loosing with these hands overcomes the fact that they have the possibility to get more/max value from weaker hands

 

This is an important concept for beginners and even intermediate players which admittedly i took a while to get used to

Imagine if we hold AA here – it's tempting to bet stupid amounts for fear of getting outdrawn, but the fact of the matter is that it's a lot more important to control the pot and get value from these hands rather than chase them out

 

The key here i think is 'what are we going to do on any non J turn if we call a flop bet?'

Hell even if we hit the Jd he's probably got re-draw outs

 

More often than not the answer to our question is going to be to fold – so preserve chips here and make that decision now
