The old classic: bet against the team you support.
You can't lose. If your team wins, you're happy. If they lose, you make money.
(Obviously this is a Draw No Bet type of thing)
The same can apply ahead of Warren Gatland's announcement of the British and Irish Lions squad on Wednesday. There's some sweat on for guys on the verge of making the squad.
Tadhg Furlong is expected to be a shoe-in but he's only been playing for his country for just over a year.
Look how nervous he is.
Simon Zebo is in plenty of experts' picks but omitted from others'.
He knows he's in for a thrilling ride.
Yes, these are gripping times and, as the official selection draws nearer, there are new names propping up and rumours of big characters being left out altogether.
Thanks to
Ladbrokes, you can put your money where your mouth is with some of the big points of contention.
The odds for Irish players to either be named in the squad or not be named in the squad are fascinating and they tell their own story. Peter O'Mahony is pretty much 50/50 and Rory Best might just not be the automatic inclusion everyone thinks.

Rory Best
1/50 to go
10/1 not to be named
Johnny Sexton
1/100 to go
16/1 not to be named
Sean O'Brien
