AA pushed too hard?

[Askilus]

Villian seems a bit loose, otherwise no good reads. $5 + $.5 at UB.

Did I pushed this to far on the river? I sometimes feel that I don't extract the maximum from my opponents with my powerhouse hands, AA, KK, AKs.

Btw, what's up with bisons converter? I get an 404 on the old URL.
