How high would the banker have to go for you to risk £10k on an all or nothing gamble?

I'd probably just about deal £10k on a blue vs £50k finish, so the banker would have to go above £50k to get me to take the gamble!

When considering this, there's the humiliation factor of potentially going away with nothing at all. I don't know why, but the thought of it seems more daunting than going away with an amount that's basically worthless anyway like £1.

If 40k was a value on the board, and I had a final two of pocket change/£40k and an offer of 10k, I'd probably deal. So I'd need the reward to be 50k to entice me into the gamble...

I put £50k but I suspect it would be somewhere between 40 and 50! (Or I'd more likely tell them where they could stick it)

I'm rephrasing this question as "what amount is twice as useful to you as £10,000"?

I think that amount is £35,000 or a bit above, so I'll put £40,000. Maybe after the £30,000 offer I might well have gone "make it £40,000 and I'll go for it" - and given the obvious intent behind the twist, I'd probably have got it...
