If they don't tech you must "DELAY 6F+K" to get FT follow up. After the 2p ender there is enough time to see whether your opponent teched or not. If they tech, and you land a knock down with 6F+K you put them into another unholdable/FT situation with 1pp. Don't worry if this move is blocked, it's -5. Only thing that shuts this down is back teching.
