Donks?
I'm a little confused. I thought a donk better was a player who bets into the pre-flop aggressor instead of checking and letting him make his continuation bet. Hell, that's something I do all the time. How else can I judge, at least online, the strength of his hand? If he folds that's a good tell his hand was weak. If he just calls that's a good tell his hand might not be as strong as he'd like it to be. If he goes over the top, well, that's usually a good tell, too.
You guys make it sound like a donk is a player who calls with nothing and then makes his hand on the river. Or maybe I'm reading you wrong.
Yeah, I'm confused.
