Bet types & conceptsSharp vs square

Key takeaways
  • A sharp is a skilled, disciplined bettor whose money is seen as informed, while a square is a casual recreational bettor.
  • It is a fast, significant move in the odds driven by sharp, informed money coming in on one side.
  • By the time a steam move is visible, much of the value may be gone.

Sharp vs square

A 'sharp' is a skilled, disciplined bettor; a 'square' is a casual recreational bettor. Operators watch which type is betting to judge how to adjust prices.

How money moves odds

Heavy money on one side shifts the odds. Operators move faster on sharp money because it is seen as more informed.

Example. A sudden, sharp-driven shift in a line is a 'steam move' — the price moves quickly as informed money comes in.

Steam moves

A steam move is a fast, significant line move driven by sharp action. Some bettors chase steam, but by the time it is visible the value may be gone.

A balanced view

You do not need to be a 'sharp' to bet well — disciplined value and line shopping matter more than labels. Bet within a budget.
