Head to head betting refers to a market where there are two possible outcomes of the match, being either one of the two teams to win. There are some circumstances where head to head betting will include a third market, being a draw.
If there is no Draw option offered, when a match results in a draw and you have placed a Head to Head bet on either team, you will be paid out as a winner with a dead heat deduction. This means that you will be paid out half of the face value of your winning bet.
For example, you placed a head to head bet on St Kilda versus the Giants in Round 5, 2018. This match ended in a draw.
Imagine you placed $5.00 on St Kilda at $3.20 odds. If St Kilda had won the match you would have received $16.00 as a wining pay out, however as the match ended in a draw you would have received a winning pay out of $8.00.
