Great run - yes, a gain of that magnitude could be entirely luck, but the money is yours now so who cares. Just keep reviewing hand histories, writing notes, and thinking about how you could play better.

As far as moving up, the *instant* you hestitate to make a bet for the sole reason of worrying about the potential $$$ loss, drop down. Good players see their chips as tools and/or weapons, not money.

That is not to say you should throw money around - just that you have to be *capable* of going all-in every time you play a hand (or more specifically, other people have to know that about you).
