Calculate returns for all Asian handicap bet types — including quarter-ball handicaps, push and void scenarios.
Whole ball handicaps (−1, +2): Your team starts the game with a goal advantage or deficit. If the result after the handicap is a draw, your stake is refunded (push/void).
Half ball handicaps (−0.5, +1.5): No draw possible — you win or lose. Eliminates the push scenario.
Quarter ball handicaps (−0.25, +0.75): Your stake is split into two bets — one on the whole number and one on the half. You can have "half win" or "half loss" outcomes.
