Well-Handicapped Horses
Saturday, September 11th, 2010Just finished reading Jon Gibby’s (relatively) new book, Well-Handicapped Horses. It’s to be thoroughly recommended, though anyone who’s read his previous Betting on Flat Handicaps will find it more like an update (on how best to use his methods in 2010 rather than 2002) than a new book. He does include a couple of new chapters on betting 2 year olds and using speed ratings, however. I won’t attempt a full review here, though a few points stand out.
Some of these points relate to the market in general and how the market is wise, or at least wiser, to many of the methods he previously advocated – in particular to draw bias. Basically, the same biases are more or less in existence, but the runners coming from the bias-affected stalls are sent off at far shorter prices than they were a few years ago. It’s not necessary to reproduce one of his examples from the book, since we can usually see a distinct correlation in known bias-affected tracks every day by comparing the ranking of the betting on Betfair (ie. favourite to least fancied) and the stalls positions of each.
Betwise produce these rankings every day – so, taking early prices today as an example, the current top 3 in the Betfair betting in the 5.20 at Chester (a 10 runner, 5 furlong race with a typically strong bias to low numbers) are drawn 1, 3 and 4 respectively. In the Sandown 2.50 (a 12 runner, 5 furlong race with a typically strong bias to high numbers), the top 4 in the betting are drawn 8, 12, 2 and 10 respectively. (Incidentally, Hoh Hoh Hoh, who has run well at Sandown in the past, is drawn 11 and is out with the washing in the betting at 25/1 – backers take note).
Thus it’s harder to make a profit by following the draw alone. Gibby compensates for this by looking largely at draw anomalies (where one part of the track is favoured/ not favoured at particular meetings) as well as longer term trends. He looks in particular to follow horses who were disadvantaged by the draw in their subsequent outings – as long as they have become well handicapped as a result.
One point that I should take issue with is when he concludes punters need to subscribe to The Racing Post and Raceform Interactive in order to spot and take advantage of these anomalies. Fine tools though these are, there are many alternative (and sometimes better, depending on what you actually want to do) data sources available. Not least of these is our own SmartForm, which adds the significant advantage of enabling you program directly with racing data. Whilst programming is an obstacle for some, once you’re over it you can automate a number of derived variables (or have Betwise do it for you), such as draw bias assessments. A type of analysis that Gibby also holds in high regard, which seems to be painstakingly manual for each race, is pace analysis. Again, with SmartForm we can program pace bias automatically, both his method and most similar ones. In fact, we use a slightly different method to Gibby and also calculate pace for likely laggers (ie. those horses who will break slowly) and hold up horses. Speaking of which, free leader and lagger ratings are now up in the Betwise Members’ area for all today’s sprint races…
