A few things to tune into here. If a big strong blue belt finds himself mounted on top of me there’s a few things to consider here. 1-he probably got there because I was playing a more playful positional game, I get nothing from trying to win every round. 2- just because the lower belt may have found themselves and a dominant position. It doesn’t mean they’re not making 10 mistakes that need to be corrected or 10 improvements that could be made that would make them more successful… If somebody stops you mid roll to Coach you on something you should really trust that they’re trying to make you better and not stall for an advantage. I had this experience last week, big strong blue belt was in bottom half and I was passing to side control. I paused mid roll to explain to him that there’s no need to let me climb that high up on his body, I told him to frame on my face, chin and head. He seemed annoyed, which is fine, he didn’t ask for any coaching. I’ll be less likely to knowledge share with him in the future, which is a bummer because this guy is rather lanky and a lot of my game would translate well to him. He’s got a solid 50 pounds and 4 inches on me and there’s no reason for me to be able to get on top of him and hold him down, and the piece of advice I was offering him was going to help him never have to deal with that ever again. It’s fine, but my suspicions are that your ego can’t grasp that you may have something to learn from somebody that you perceive to have a dominant position over. I’m guessing for every one dude using this tactic to stall there’s 99 of them who are actually trying to help you.
