Move 5. Nd4 and you're already in trouble. You don't see elementary threats. Also 1. Nf3 is not the english, I believe it's the reti, but it could also be a King's indian attack depending on how he plays it... In short, I'm not positive of the name for it but the english is 1. c4.
Wow man, you really played that guy a lot.
Why actually? Doesn't this kill your rating?
it's remarkable how long it takes before he attacks and I think that might be his weakness. He plays some kind of Indian defense whilst he is white, which might cost him the advantage of beginning...
