When the Pinnacle price is over $2, and the arb is 100% or less, then don't worry about the retirement rule. It works in your favour. It's when the Pinnacle price is under $2 that it begins to work against you.
This of course assumes there is no player more likely than the other to retire. If the player paying over $2 with Pinnacle has a history of retiring, then that throws in a curve ball.
If you take 1000 bets on a Tennis match with the head to head odds where the Pinnacle price is $2.25 and the other book who voids bet unless the match is completed is paying $1.80, I am happy to take this on. These head to head odds will give you a 100% return (break even) in a completed match, but if there are ten retirements after the first set in those 1000 bets, the only way you make a loss is if the players paying $2.25 retire in seven of those ten matches.
Obviously the higher the Pinnacle price, the more this plays in your favour. It's a different form of arbitrage betting where you place bets based on books having different rules for settling bets.
Cricket is another one I like to use to take advantage of different rules.
For example, the Big Bash, total innings runs on Betfair. Betfair rules stipulate that as long as five overs are completed in the innings, all bets will stand on total innings runs. A lot of books require a full innings to be completed for bets on this market to stand, while Topsport requires 90% of the innings to be completed. The way to use this to your advantage is to back the overs with one book, and lay the overs with Betfair. If the rain comes, then you're laughing.
Not sure if anyone else got on, but Sportsbet were offering odds of Tomic to leave the jungle at $1.70.
In the last 5 mins of The Project before I'm a Celebrity Get Me Out of Here, they crossed live to Dr. Chris Brown and Julia Morris who confirmed Tomic had indeed left the jungle. The thing was, Sportsbet didn't pull the market, and soon enough the odds were hammered into $1.30 in the space of minutes, while I could only chuck down a couple of hundred (as I was still weary that the hosts may have been playing a ruse, and were drumming up fake-speculation.)
Spewing I didn't put more down, but still I can't complain with a free $200~ or thereabouts.
Trey Flowers NO sacks on 365 at 1.40 - over .5 sacks on Crown at 6.50 (also 1 or more on Neds at 3.90)
Fletcher cox NO sacks on 365 at 1.40 - 1 or more sacks on Neds at 3.80
Edit: Prob not worth it in the end for 365/neds arbs, not sure how books will grade half sack towards each side... prob still worth the risk for me on the Flowers 365/crown one
Edit2: someone checked on chat and bet365 settlement team has said a half sack wont count as a loss on bet365s "no" market. so the crown/365 arb should be good.
1 sack = crown win and 365 loss
Half sack = bet365 win and crown loss (maybe push as it is listed as 0.5)
No sack = 365 win and crown loss
