I was recently watching Peter Clarke's "Key Concepts" videos and he talked a great deal about protection. This, and many other concepts related to pressing equity in thinner spots, are concepts I am not applying well.

I posted my stats (here).The reply chains brought up the same stuff that Clarke talks about in his video (low WWSF, low aggression, their correlation) as well.

How do I increase my aggression? Particularly on later streets, paricularly when I am defending either against a 3bet or in the blinds.

My plan
(1) I continue to review every medium or large pot after a session and try to identify spots where I didn't raise or bet and could've/should've
(2) Drop cold calling range so that when I head to the flop I'm more likely in a spot to be aggressive
(3) selective stealing and isolating raises preflop to make sure ranges are appropriate for opponents

What else should I look at? How have you solved these problems?
