Marcus “Buchecha” Almeida is widely regarded as one of the greatest heavyweights in Brazilian jiu-jitsu. Competing for Checkmat under Rodrigo Cavaca, he stacked IBJJF Worlds titles in weight and absolute and won ADCC +99 kg gold in 2013 and 2017.

His game mixed wrestling entries, athletic pressure passing, and top-position attacks that later informed his MMA career. On Open BJJ he sits beside double-leg, knee-slide, and half-guard pages as a competition reference rather than a novelty stylist.
