i tried 2 techniques today during randori and im not sure if i was doing them right. the 1st was a triangle choke variation. the guy was much bigger then me so i couldnt sinch my left leg behind my right knee. i reached my right hand over his back and grabbed my ankle for ruber guard, i then grabbed the same leg with my left hand and tried to finish the triangle with my left arm on the side of his neck. i was in good position and he said he had a hard time getting out and he started feeling the choke sometimes. i didnt squeeze hard bc i didnt want to hurt him if it was the wrong technique. i cant find the video online to this variation. did i need to hip in? he was a big guy and i dunno if id be able to do that, should i pull his head down by crossing my right hand over on the back of his head? the 2nd was the same big guy over me on side control. i was on bottom. lets say im laying down and hes on my right side. i took my left hand and reached it around his neck and grabbed the back of the lapel on the neck with a thumb in. i then hipped out a little to create space and circled my left leg over his head. then i hipped in hoping for the choke. so hes still on the side with my left leg over his left side of his neck and my forearm over his right side of the neck. this is harder to explain then i thought but i hope you get the point. any help is appreciated.thanks!
