Odds Conversion Chart

Fundamental to assessing value in any betting event is understanding the implied probability that is reflected in the given odds. Essentially you want to bet odds that have a lower implied probability than your own personal assessed probability of that particular result occurring.

For example, let's say that West Coast are 1.60 to win at home against Collingwood in the AFL. The implied probability in such odds is roughly 62.5%. But you've assessed that West Coast are a 70% chance of winning the match, meaning that they should be odds of 1.42. If you've done your homework right and your assessment is accurate, you've found a value bet.

Thinking in these terms, having it almost become second nature is truly key to long-term betting success. If you want to understand the nature of value, you first have to start thinking in terms of probability.
