Yesterday I got tapped out by my training partner, which is not so new, the interesting thing was he said he used a crucifix to do it. Now, I've never been shown a crucifix, so I don't know if it really was. Also, because my head was in his armpit, I couldn't see what he did. So, how does one set up a crucifix? (He did it from my half guard) And how do I defend it? I tried to free my head but no luck, I ended up in his guard but that didn't relieve the preassure. Please help, thanks in advance guys.
