I think the fact that he went 33-10 kinda proves something !
When I was really good back then, I played a bit promod, and it is hard getting those kills, but there is always one or two people who are pr0.
Actually I win some games

Dd
but you see, i agree with houston on this one. The way you say it, it seems that you speced him for only about 30 seconds, concluded that he hacked solely on the fact that others were calling hax and his score and his playing did not match all of a sudden.
You see, everyone gets those little period in game when he suddenly gets bad and dies like 10 times in a row while going hot overall in a game.
