Paintbrush defence
Also known as Americana Escape — the canonical term used on this site.
Colloquial — defending the americana under its catch-wrestling name
Paintbrush defence is the colloquial name for defending the americana, taking its label from the sweeping motion of the opponent’s hand across the mat that gives the attack its nickname.
Etymology. “Paintbrush” names the attack, so the defence borrows it wholesale. The term travels through catch wrestling and older sambo vocabulary rather than through the Brazilian lineage, which is why the same defence is described as keylock defence or americana defence depending on who is teaching it.
Disambiguation. This site previously filed “paintbrush defence” under the straight arm shoulder lock. That was wrong on both counts — the name belongs to the americana, and the two attacks load different structures, so the defences do not transfer. A bent-arm shoulder lock is answered by fighting the rotation and the grip; a straight-arm one is answered by bending the elbow.
Mechanics. The americana needs the elbow fixed and the shoulder free to rotate. Turning onto the trapped side takes the shoulder out of external rotation, and getting the elbow moving toward the head restores the range the lock removed. Both have to happen before the figure-four is fully closed.
Cross-reference. “Keylock escape” is the wrestling name. Full escape coverage on Americana Escape.
