He has a lot of potential, I think. His macro is solid and his micro (fungals, infested t bombs, queen defense) is pretty impressive. He admits himself that he doesn't know how to defend cheese. Given that his build is pretty greedy, he's going to get a lot of practice. ;-)
I wonder if the answer to cheese is purely a question of how defensive to get. Spines supported by queen transfusions are ridiculously strong. Whether it is possible to reliably defend cheese without getting economically behind due to the spines and queen investments, I have no idea.
