What we measured
This counts deals where two or more players each hold two unpaired hole cards that both connect with the flop — so each player flops two pair using both cards (for example K-9 and Q-9 on a K-Q-9 flop). It is the classic 'my two pair ran into a bigger two pair' cooler. The per-deal figures assume every such player sees the flop.
How it was calculated
Monte Carlo: deal every player and a flop, then count deals where two or more players each hold two unpaired hole cards that both pair the flop.

Why is two pair over two pair so costly?+
