[Kevin Sevcik]

Penalties aside, this still isn't a chokehold because your opponent can still score points for crossing, breaching, challenging and scaling. Plus all the boulders that start on the field. A chokehold is a strategy that guarantees success if you achieve it. If the opponent can't prevent you from doing X, then nothing else they do will matter because you'll win. And it really meant to refer to a single technical challenge.
Technically, a chokehold strategy would be, say, preventing them from accessing any boulders while breaching their defense and capturing their tower. But at that point your fool proof strategy is to win a match, which isn't informative.
The last real chokehold I recall was 2002. Keep all the goals off your side of the field and get atleast one on your opponent's side, and you won. That was a single technical feat achievable (just) by a single robot.
