Laying a book in a tennis tournament

Scott Ferguson talks us through the golden rules of laying an ante-post book on a tennis tournament

Tennis punters aren't treated to many chances in long-term antepost markets. Racing fans get their big races up to 12 months in advance and a swarm of other races in a shorter time-frame, while football and golf punters can have weeks or months to get involved in their big events.

There is an art to laying a book in any market - it comes down to timing, margin and anticipating what the market will do between now and the end of the event. There was an excellent thread recently highlighted in our InPlay newsletter discussing laying every player in a major golf tournament, read it here.

Tennis, as you'll soon notice, is quite different. Having a draw full of knockout matches means the overall champion needs to defeat only seven opponents rather than the entire field. One player, such as Roger Federer, can dominate the market meaning you have to be careful about withdrawals and how to price up players based on which side of the draw they may be. With the advent of Winner with Federer markets, this adds a large safety net for layers - no longer can you get skinned when the 1.6 shot pulls out unexpectedly due to injury or fatigue.

When laying a book, the aim to is lay as many selections as possible at as low a price as possible. The longer the period before the event, the more margin you need to build in, to allow for various events - some players will run hot, others may have injury scares. When the players concerned at well down the market, then prices are independent of each other but if Djokovic or Nadal succumbed to an injury a few weeks before a Grand Slam event, the price of players around them in the rankings would shorten.

The first thing you need to be aware of is that bookmakers don't get green books very often. Before an event (race, match, tournament), they'd be in profit for every selection maybe once in every 1000 markets, unless they were laying off along the way. Bookies can't tell a punter that he can only have £23.17 on a selection so they could have a perfectly-framed book, nor can they tell someone to double their bet to smooth out their risk. Betfair traders have options - you set the risk you're prepared to take and which selections you are prepared to lay.

It's all gone Pete Tong at Betfair!

The Christmas Hurdle from Leopardstown, a good Grade 2 race during the holiday period. But now it will go into history as the race which brought Betfair down. Over £21m at odds of 29 available on Voler La Vedette in-running - that's a potential liability of over £500m. You might think that's a bit suspicious, something's fishy, especially with the horse starting at a Betfair SP of 2.96. Well, this wasn't a horse being stopped by a jockey either - the bloody horse won! Look at what was matched at 29. Split that in half and multiply by 28 for the actual liability for the layer(s). (Matched amounts always shown as double the backers' stake, never counts the layers' risk). There's no way a Betfair client would have £600m+ in their account. Maybe £20 or even £50m from the massive syndicates who regard(ed) Betfair as safer than any bank, but not £600m. So the error has to be something technical. However, rumour has it, a helpdesk reply (not gospel, natur

Spot-fixing - you will never, ever be able to stop it

According to this report , IPL tournaments so far have been rife with spot-fixing - that is fixing minor elements of the game - runs in a single over, number of wides bowled etc. The curious part of that article is that the Income Tax department are supposed to have found these crimes. What idiot would be stupid enough to put down 'big wad of cash handed to me by bookie' as a source of income? Backhanders for sportsmen, particularly in a celebrity- and cricket-obsessed culture like India are not rare. They could come from anything like turning up to open someone's new business (not a sponsor, but a 'friend of a friend' arrangement), to being a guest at some devoted fan's dinner party etc. The opportunities are always there, and there will always be people trying to become friends with players and their entourage - that is human nature. This form of match-fixing (and it's not really fixing a match, just a minor element of it) is very hard to prove, but also,

lay the field - my favourite racing strategy

Dabbling with laying the field in-running at various prices today, not just one price, but several in the same race. Got several matched in the previous race at Brighton, then this race came along at Nottingham. Such a long straight at Nottingham makes punters often over-react and think the finish line is closer than it actually is. As you can see by the number of bets matched, there was plenty of volatility in this in-play market. It's rare you'll get a complete wipe-out with one horse getting matched at all levels, but it can happen, so don't give yourself too much risk...
