I had bet on Matosevic +4.5 games in his match against Nishikori. Matosevic retired after the first set(losing 6-4) and my book has paid me the bet like a win. What bothers me is that I always thought that AH bets are paid as win/loss only if the match is finished and returned if one player has retired. Should I write them to look it up or should I just take my winnings. Advice will be appreciated.
P.S.There are no specific rules in my book as far as AH bets on tennis are concerned.
