forecast bet; quinella or perfecta bet
A bet type in Japanese public racing (horse, boat, bicycle, etc.) that predicts the top two finishers. The exact order may or may not be required depending on the specific sub-type (連勝単式 or 連勝複式).
I buy a forecast bet ticket at the horse races.
連勝式には単式と複式がある。
Forecast bets include straight forecasts and quinella bets.
