Known as the full mount in Brazilian Jiu Jitsu and other grappling arts. You sit astride your opponent knees up high under armpits to avoid being bucked or alternatively lying on top of your opponent grapevining their legs with your own whilst your arms act as stabilisers and your chest smothering their airways. When the opponent weakens from exhaustion/asphyxiation one should then consider the following options.
The high armpit position allows transition to armbars the other to various choke holds.
