dry / rainbow
Share of each range that is sets, two pair, overpairs, straights or better, and combo draws. This is who wins the big pots.
With the range and nut edge together, a small bet with the Button's whole range profits. Try swapping the lowest card for a middle connector and watch the edge move.
The classic continuation-bet board. The button opens every AK, KQ, and big pair in the deck, while the big blind mostly connects by pairing the seven or spiking a lucky deuce. This is the texture where betting small with the whole range prints.
