Who has the range advantage on A 7 2 rainbow?
Big Button edge: the Button has more underpairs, and the Button has more strong top pairs.
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.
The edge is the Button's but nobody holds the nuts here. Take the small pots down and avoid bloating anything. 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.
