Ive had this problem a few times and it really gets me steamed afterwards and it happened again today. Basically whenever im facing somebody really good when rolling and I pull something off perfectly and Im on the threshold of subbing them... I sorta freeze up/hesitate and they escape. example : today I rolled w/ this guy who is really good and i went for an oma plata to sweep but he saw it comming so i swung my leg back and over his shoulder - getting him right into a triangle. I thought "oh shit.. this is perfect...imma sub this fool.. cant believe it" so i start to lock the figure-four in and i dunno where i go wrong but it's like.... i just hesitate. I lock it in and I start to think "damn is it locked in enough? lemme lock it in more... no wait it's fine.... wait what should I do now.." when I should be thrusting up w/ my pelvis and pulling on the head. Such a simple set of moves to do when you got that figure four but It seems to all go out the window when im there. by this time - he has managed to escape the triangle cuz ive given him too much time to think instead of going for the kill - which is what i need to work on. any of you have this problem or ever expereince something similar? It's like a head game u know? I bet if I thought of the guy like anybody else then i would have slapped that shit on so fast.
