Thank you for posting.
You always want a villain to call when they are not getting the right price in a cash game. ICM in tournaments changes that.
It is not uncommon for villains to improperly apply strategies. The article I listed talked about Ike 5 bet shoving Ah5h and how it would be a good idea IF the button had enough folds.
Then just below that, stated the most important part. For 99% of games you should never do this. Most readers will forget the 99% do not do this and just remember but IKE who is great 5 bet shoved Ah5h
JJ 1010 4 bet shove is terrible vs strong or average players. You will always be called by 50%+ equity hands and you will fold out all hands with 45%- equity.
You need 65% weak calling station players who 3 bet wide ranges in your player pool for that to be profitable long term.
