I have a list
{{1,2,3,4,2,3,4,5,3,2,1,9}...}


for example, {a,b,c,d} a and c are in the odd positions and b and d are in the even positions.

I want to separate all the evens from the odd positions
just like this

{{1,3,2,4,3,1},{2,4,3,5,2,9}}



ps.
I have been working on this two days, and basically what i think it comes down to, is finding a way to recognize which positions are odd and which positions are even.
