Harness Racing Books

Chaplin thoroughly investigates pace and breaks down speed for each portion of a race. He tries to quantify a horse's exertion level during each portion of the race. After doing a fine job in those regards, he totally blows it by suggesting the player can profit by playing any good shape overlay, regardless of how firm your opinion is on that contender and even goes on to state that the more contenders in a race, the better the bettors chances become. The seasoned player knows that these assumptions are simply not true and any time you don't have a firm conviction on who the winner will be, no amount of overlay will profit you.
After all, it's the horse with the best chances of winning that wins in the majority of cases, not necessarily the one with the best overlay odds. Anyone who thinks it's easier to pick winners by selecting any horse just because he's NOT the favorite is thinking backwards.
