Taught my first adult no-gi class today. Professor was at another location today. My only instructions for the class were "knee shield".
I'll be honest. I don't play much knee shield. Well, I get into knee shield a lot, but I use it to transition to other guards (usually deep half). So when I got to the gym, I googled, "knee shield attacks". Ended up using 2 that I found (back take, a john wayne type of sweep) and then a guillotine. The guillotine was if the opponent underhooks your top arm.
When I demonstrated that one, my uke (who is a very close personal friend) gave me a weird look. Said something along the lines of, "I wouldn't go for an underhook on the top arm, I'd be trying to smash the legs."
I told him, "If I'm going for the underhook, most people are going to pummel for one."
He just shrugged, but went ahead with the drill.
Later on, I rolled with him in the second round of positional sparring. Within 3 seconds I baited him into going for the underhook that he said he wouldn't go for.
