Let's see how often you would need to double up in order to make raising 5x BB with a baby pocket pair a profitable play.

Let's assume you double up (win 100 big blinds) x % of the time, and lose 5BB the other (100-x) percent of the time.

(100-x)*(-5) + (x)*100 = 0 (break even)

x = 4.76

So you would have to double up 4.76% of the time for this play to be profitable. I guess thats could be possible. But I'm not considering the possiblity of losing your entire stack if the other guy flops/draws a better hand.
