I run a lot of parlay bets for small money mostly, and every now and then I will see that a game or two within my parlay's are listed as "cancelled" when I check the parlay status. What circumstances cause a book to cancel a bet?
I've got a monster parlay going right now and even though I have yet to lose on it, one of the games on was just cancelled . Hate to see what happens should I win the bet, haha.
