My approach here was to fold to any raise. I figured a check / call was going to lose it almost 100% of the time, but I thought there may be some slightly better chance of getting everyone to fold to a bet. Check/ folding would be such a painful thing to do in this large pot.
I thought I'd try take my tiny % chance, although it's very hard to say whether everyone would fold the 1 in 15 times necessary to make the bet profitable.
