Yeh I found top game you gotta keep good posture in guard & when passing / past guard keep low and heavy - unless there's a scramble on of course.

Bottom game it's just the opposite - when in guard you should be constantly active with pressure through sub attempts / sweep attempts or the threat of standing up, so that they can never get comfortable or see what's coming next. Escaping is the same, constant pressure with hip bumps, foot drags etc.
