I just know for me, I've lost against J2 three times in my life and tilted losing to K3.
One time with two pair going against J2 in limit holdem with made the person hitting the 2 on the river to a preflop raise.
Another time My pocket Ks lost to someone with J2 and made pair 2 during my shove, who flopped the J on the river.
Same situation against K3 when I held top pair.

Donks call anything. Just make sure you know their ranges and to catch them when you have the best expected value hands. If your bankroll is big enough, you can take a few cold losses.
