Hi, looking for advice on opening up people for attack when they get a good defensive posture and stay tight with a focus on attacking from closed guard and attacking from mount. In closed guard I typically go for the Roger gracie style of arm drag (thanks trumpetdan) and work bumps, collar chokes arm bars and pendulum sweeps off of defense to it. I'm beginning to have trulouble getting any offense going when people defend and keep elbows in tight with good posture. This is particularly problematic against anyone who is strong enough to shut down any attempts to pry their elbows from their body. Second problem is the same situation but from mount position, when a guy keeps his hands close to his collar but elbows tight against his body and against the ground to stop you sliding up to high mount. Once I get something going. I feel like I can move between collar chokes, arm triangles, arm bars and back takes, but with some guys I can spend a full five minute round trying to get a hand in the collar or pry an elbow free when they stay tight. I've tried ezequiels and Americana attempts to setup other options from their reactions, but some guys its impossible to get any movement out of them to play with. Any time I get aggressive to try to make something happen is usually when the better guys take the space that gives them and start working escapes. Any and all help appreciated.
