Spot the pattern before you study the percentage.

The color tells the story first. Green identifies favorable matchups, red exposes the hands that have you in trouble, and neutral cells mark the close decisions.

  • Pairs run down the diagonal
  • Suited hands sit above the diagonal
  • Offsuit hands sit below the diagonal
  • Every cell includes its equity estimate
