The aggressive opponent type (LAG up to maniac).
First adjustment: bluff-catch wider and trap with strong hands. A player with VPIP (participation rate) of 25% or more who raises on three quarters or more of the hands they play is read as aggro. Example: VPIP 32% and PFR (preflop raise rate) 28% is aggro, because the PFR is at least three quarters of the VPIP (24%).
