Nice! when did you get those odds? I'm guessing before the last 3 games?
See the odds 18/19 thread, SlyBet only just re-introduced the 200/1 odds after the Mansfield win! They'd closed the market prior, presumably due to completely writing Notts off.
Not a hope in hell of winning the bet, but as driller suggested those odds would be tempting with an option to cashout. If we did happen to win the next couple of games they would fall quite sharply, that would be the time to cut and run.
