Rick (on the left in blue t-shirt) is attacked by Tyler (in black gi).
Rick simply holds his Sanchin Crane Stance and absorbs Tyler's punch while simultaneously exploding into his neck (or other appropriate target).
It is swift and very effective, especially in close quarters where movement is limited. You can't see Rick's feet, but his right foot can be 'hooked' behind Tyler's left foot to execute a 'knee trip' and further off balance Tyler.
From here Rick can followup with whatever the situation calls for. It depends on where Tyler moves.
