OP, I can't help but wondering about one thing: how will the change of odds affect your betting history? Granted, you'll be at a disadvantage with the situation where the old [and lower] odds being applied to you instead of the newer and higher odds, but your placed bet is a losing bet, and thus would 1.5 or 2.15 still matter and affect your decision regarding the bet? Will you cancel your bet on Fritz's winning because the odds changed?
