How alarming is Hero's 3-bet? Does Hero have a 3-bet bluffing range? Or is the 3-bet always for business? Hero isn't betting a reasonable draw. His "business" range is no more than AA, KK, AK and A9(s?). six combos that crush villain (hero holds 95% equity), nine AK hands with 20% equity and one A9s with 10% equity. Yes, villain is crushing that range, but still it seems like a time to take stock before acting.
I don't have the impression that villain gave much thought to the action. Villain seemed more focused on his check-raise trap than the trap Hero laid. It would be interesting to know what villain was thinking here and how he/she perceives hero.
