It's a loss, try not play with 3 way betting unless know what it is...
Although a draw result is found in Asian handicap betting as well, it is completely different from the EH. When you place a wager on a -1 Asian Handicap bet, if the favorite wins by one goal, you’ll get your money back, as the bet is considered a “push”.
On the other hand, if you place a -1 European Handicap bet and your team wins by a single goal, then you will lose your bet. That is because in Euro handicap betting you can’t get your stake back. The only way you could have won that bet, would be if you had placed a “draw” bet, where you expected a one goal margin win by the favorite. This option does not exist in Asian Handicap, given that it’s a 2-way bet.
