So basically yesterday hal played some eyetoeye duels and streamed it. He had random opponents and then he started to play k1llsen right after it. He won 3 maps in a row (but all the games were close), and then a bit after it, played 1 last game still against k1llsen, which he lost.

So final score was 3 maps to 1 in favor of hal (he had to go to sleep after his last game against k1llsen, he said he felt tired etc, so that's why he lost this one, at least according to him (afaik)).

Like I said, all the games were close and k1llsen was definitely a though opponent.

Do you think that if k1llsen starts practicing more eyetoeye duel he can finally manage to beat hal more consistently or do you think that even with hard practice on this map, hal will still be the best at it ?

Hal played a lot of eyetoeye duels, especially against his older brother stermy, and he's better than stermy aim wise.
About k1llsen, I have no idea, but if i'm correct, I don't think that he played a lot of this map, but i might be wrong. k1llsen plays mainly a lot of duel and 4v4 CA.

Oh and btw, k1llsen is using logitech g303 mouse, finally! :) But he still plays with mouse accel, do you think that it's what improves his flick rails and overall rail consistency, and also his defensive rockets, but makes his lg aim a bit less 'stable' and 'solid' (at least compared to heavy shaft players like hal) ?
