This is more of a broad question, but what information solves this problem? Combo work? 3! and 4! theory? Putting my phone down during hands I don't play and paying attention?
Villain smart, late 20's local who always wants to bump game up to $5/$5 so he can match my stack. Has full repertoire of plays available to him. 3bets often, and seems to recognize right configurations to do so. (LAG opens CO $20, V3! $65 ATs otb). Slows aggressiveness when he plays me but versus others, he really does go after weakness. And most of the regs where I play will overfold when the pot gets big. He doesn't seem to have the touch with the downbet early in the hand and plays more by feel, worried others will view it as weakness and play back at him (from what I've seen versus our competition he might be right).
Hero likely viewed as competent. Talked shop a couple times with villain. He is aware I will call him down lighter than most without too much monetary concern. Probably views me as solid.
