Patience and reaction time are big ones. Speed also.
Would Anderson speed not translate to being more aggressive and throwing first?Anderson was big on countering, too.
Gotta have the defensive movement and speed to avoid getting hit, allowing you to exploit opponent openings after they throw.
Those CKB boys aren't really counter strikers though. They're for sure amazing at feinting but they tend to throw first even if they're backing up. Even Izzy isn't a counter striker despite having a great counter left hook he just doesn't like to wade forward. Instead of countering he usually just dips the hell away.And reading your opponent too. You watch someone like Izzy, actually all the CKB boys, they throw feints early to see how the opponent reacts. They try to get a gauge as to how the opponent will react to strikes and plan follow up attacks once they throw the strike for real.
