HU strategy I've used lately LIMCASH

[cantsitstillbr]

Just started working on my heads up game. When I'm against an aggressive opponent I've been using this line lately when getting check-raised on the turn. Cant tell if this is good or if I've just been running good. Thoughts?

Button is SB.

Hero raises K4. BB calls.

BB check-calls

BB check-raises, Hero 3 bets, BB calls

BB checks, Hero checks

Thoughts?
