KK, a pocket pair, plays 53s, a suited hand. Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind.

A lead of 58.26 points is large but not decisive: 53s still takes about 206 of every 1,000 deals. About 0.47% of boards chop the pot, which is why equity sits slightly above the win figure for both hands.

Place 2 of 169 belongs to KK and place 146 belongs to 53s in the ranking against a random hand.
