Double board bomb pot calculator: equity across a shared deck
Study PLO4, PLO5 and PLO6 double board bomb pots with two boards drawn from one deck. The free calculator separates each board’s equity from the combined pot share and the chance of scooping both boards.
Set up the two boards
Choose the game and player count, then enter every player’s hole cards and the known cards on the top and bottom boards. Add known dead cards if needed. Cards used in a hand or on either board cannot appear elsewhere in the same deal.
Enter the real state of both boards. Do not run two independent single-board calculations and assume they describe the joint outcome: both boards consume cards from the same remaining deck. This matters especially for scooping and split-pot outcomes.
Interpret board equity and combined equity
The top and bottom board equity values describe each player’s expected share of that board’s half of the pot. Combined equity averages the two board shares, assuming each board receives half of a common pot. Scoop probability counts outcomes where one player wins both boards outright.
A player can have 50% combined equity while never scooping, by winning one board and losing the other every time. Combined equity alone therefore does not describe how often the result is a full win, a half, a quarter or another fractional share.
Worked example: half the pot is not a scoop
Select PLO4 with two players. Enter P1: A♠ A♣ 2♠ 3♣ and P2: K♠ K♣ 4♠ 5♣. Set the top board to A♥ A♦ 6♣ 7♦ 8♥ and the bottom board to K♥ K♦ 9♣ T♦ J♥. All cards are distinct.
P1 makes four aces on the top board and P2 makes four kings on the bottom board. Each wins one board outright, so both have 50% combined equity and 0% scoop probability. The half-pot outcome is certain. Change one board card at a time to see which player’s prospects actually change.
Calculation method and limits
The calculator counts the legal remaining two-board runouts. It uses exact enumeration when that count is within its calculation budget and Monte Carlo sampling otherwise. Check the displayed method and sample information; an estimate is not an exact guarantee.
Results assume the entered players reach showdown and share the same pot, with half awarded to each board. They do not model future betting, fold equity, rake or separate all-in side pots. Study the two-board outcome distribution alongside the board textures before drawing strategic conclusions.
