Yes I won't say the contrary, I'm impressed of what he did.
But maybe, as dondon151 said, my opponent was way too cautious (but didn't see the backdoor he let me), and what was interresting at the beginning was way too long and felt like sadistic at the end. I had the impression it would never end. That's in this way more than in setting the pin that I felt it frustrating.
He asked me if I wanted to resign, but I prefered to see where it would end.
