I'd go with unregister, then play several more sats till you get another ticket. Hopefully you will come out ahead, and be able to consider the big game as a freeroll.
That notion of scared money is bigger than any of us realize. So my idea would eliminate that notion.
Yes Annie, you can (at most sites) un register and get T$ (tourney bucks). They spend just like real money
when you want to get into a different tourney. You CAN NOT however sit down at a ring game with T$'s.
