In one of my recent fights I squezeed for NS choke at least 10 sec. Then nearly got the Omoplata sub (i let him roll after about 5 sec of trying to crank). It was 4:4 and ad the end of the fight my opponent ended in some sort of spiderweb for the last seconds. So the ref gave him an advantage - after the fight was over. No advantages throughout the fight for me. Even over here, in Germany, there's 10thpjj/Rubber Guard bashing&hate. In the end it only makes us stronger.
