i know, pulling half guard was so inferior that i was only able to do it through all my matches at the pan ams. it put me in such a crappy position that i only walked away with a silver in the medium heavy blue belt masters and a gold in the blue belt masters absolute. imagine how much better i would have done if i had fought tirelessly for that two point takedown. get over yourselves and realize there are a lot of styles and games played by other people(as in not you) that are all part of the game of grappling.
as far as the op goes, get control of his sleeves or a grip on a lapel so when you pull guard you can really control the guy and pull him into your guard. just sitting down gives him plenty of room to run around you and give you all kinds of problems.
before the flaming and bs ensues, think of this guys. i'm not saying that my way is the only way. i'm just reiterating that you have your style and i have mine. that's why we get out on the mat and bring the two together and see who has the better one on that day. for me whatever happens, he takes me down, i take him down, someone pulls guard, that's the game and i am ready to play it. good luck in bashing me, as i hope it's at least humorous.
