Thanks Mojo, that's pretty much what I thought. I went with the "head's you get a quarter, tails I get your stack" line of thought, and played more speculative hands cheaply, folding quickly if I didn't hit or get the right odds to chase a draw. I also devalued cards like A-10o because I couldn't get a good read on whether I was ahead or behind in that situation.

I managed to double-up against an unknown fish before running out of time around midnight.
