How should I have played this hand??

Hi everyone, I have seen some good advice on these forums, been reading for a few months now about the same amount of time I've been playing online poker. Had the hand below happen tonight and wanted to know how others here would have played it:
My read on Eskimo x so far had been he was the next best player at the table, meaning he was betting and representing his hands as one would think, hadn't shown down any junk hands. The chip leader was just getting lucky, making bad calls and sucking out every time almost.

No-limit Texas Hold'em $5+$1 (real money), hand #1,132,234,090
