This is a horse racing betting prediction book published by Kaiseido. It uses a method of selecting bets based on a chosen "axis horse" and race conditions. It does not support trifecta or trio bets, so some adjustments are necessary. Please note that some of the past data used to determine the axis horse may not be applicable to current conditions. This item was purchased approximately 30 years ago. While there are scratches on the front and back covers, there are no noticeable stains or damage inside.
