J9o on 8s Jc Kh 4s Kc — full decision breakdown

A real hand: J9o pre-flop, board 8s Jc Kh 4s Kc, ended with two pair, net -140 chips. Every decision point, street by street.

Starting hand

On the Chen formula, J9o scores 6 — a marginal hand worth playing in position and folding out of it. The formula takes the higher card (A=10, K=8, Q=7, J=6, otherwise half its rank), doubles it for a pair with a floor of 5, adds 2 if suited, then subtracts for the gap between the cards. It is a fast rough estimate for whether to enter a pot, not a post-flop tool.

The line

• Pre-Flop (pot 70, facing 20): called
• The Flop (pot 90): checked
• The Turn (pot 90): checked
• The River (pot 330, facing 120): called

Pot odds at each decision

Equity needed is the call divided by the pot after calling — the minimum win rate that makes the call break even. Compare it against your estimate of your hand's equity. Note this is immediate pot odds only; it ignores chips you might win on later streets.
