Who has the range advantage on A 7 2 rainbow?
Equities are close, but the monsters live in the Button's range: the Big Blind has more weak top pairs, and the Button arrives with more air.
BTN vs BB single-raised pot: the button opens, the big blind calls.
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.
Equities are even, but the big pots run through the Button's range. Build them when the Button holds the goods and let the rest go cheap. Try swapping the lowest card for a middle connector and watch the edge move.
Both players hold aces here, and that is the trap: the big blind defends plenty of weak aces that are now dominated by the button's AQ and AK. The pot looks quiet until kicker trouble arrives.
