[Claymores]

Still no idea of whether Dane has a chance, here is odds change:

I've no idea if Dane has any chance or not to really win (it is irrelevant to the following), but in gamblers' jargon this is known as a "ramp".

Under a ramp you place bets [say on Dane] at the longer odds when something semi significant occuring. The process of buying the bets alone causes the odds to tumble, then you 'sell' by laying against [betting Dane doesn't win] at the lower odds.

Easist analogy I can think of is the Stock Market in reverse - buy high sell low. The difference between the 'buy' and 'sell' becomes pure profit irrespective of the outcome of the event in question.

It is the way Stock Market traders operate - they don't actually care if X company invent a cancer cure or not, or if the crops are gonna fail in Kansas - just the profit to be made on trading at the correct time.
