I am of the opinion that Team A will not win. So if i am correct and Team A does not win, then obviously the "play" here is to back both the other teams to win.


Mad,

If you stake $50 on both B & C then your outcomes are:

-$100 A wins
+$450 B wins
+$155 C wins


Instead you should be staking so that you get a near identical outcome irrespective of whether B or C wins.

In rough figures the odds imply that a C win is twice as probable as B, so the B:C stakes should be 2:1 or 67:33.

The combined $100 stake thus produces:

-$100 A wins
+$263 B wins
+$242 C wins

Not too far away from identical wins for B & C.

Your Edge cannot be quantified unless you have both True Odds and Available Odds.

If you think that in this ~100% market that A is bad value, then the B & C combination would present you with good value.

So your correct strategies are:

- Back B&C as above.
- Lay A

On Betfair I would probably offer both correct strategy Lays and Backs but at minimum stakes. Then after matches I would adjust my positions to try and end up close to :

-$100 A wins
+$250 B or C wins
