The jab-feint use by Canelo above was beautiful.
I've used the right hook to the body to set it up before while boxing with decent success.
In muay thai, I like to use it if I see my opponent using his right hand to parry my left teep.
To be honest, regardless of the style, it depends on who ur sparring or fighting. U just need to look for what shots make them move their protecting hand down or forward. When u see that, u have ur set-up.
