Claudio Calasans's game is defined by excellence in rear naked choke, armbar, side control, guard passing. Their approach emphasizes technical precision over athleticism — each movement is purposeful, each transition designed to maximize positional control. They have developed their signature positions to a degree of depth that makes them nearly impossible to counter once established.
