No shoulder pressure, only technical passing, no explosion or torquing on submissions (guillotine, kimura...) I do a lot of guard playing, I sweep them like dudes. If I need to escape something I go technical, with basically no strenght involve. Sometimes I get tapped by girls because of that.
I think it helped me to get more technical and I need less strenght against bigger people because I actually do the right thing instead of just muscle it
It helps me to get the best of those rolls, it's that or me and the girl have a useless and unsatisfactory 6 minutes roll.
To be honest, I roll with girls about once or twice a week wich is about 5% of my rounds in a week, if it was about 20% I would get pissed.
It's pretty much the same rules with guys 30 or 40 pounds smaller than me.
Being 185LBS, I hate it when the 220 + guys are in full smash mode against me.
