Who has the range advantage on A 2 3 rainbow?
Small Button edge, but the Big Blind holds more of the strongest hands: the Big Blind has more weak top pairs, 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 Button is ahead on average, not in the big pots. Bet the Button's strong hands, keep the size honest, and slow down if the pot gets large. Try swapping the lowest card for a middle connector and watch the edge move.
A strange split: the button holds more aces, but the big blind holds the A4, A5, and 45 type hands that just flopped wheels and wheel draws. The top of the board belongs to the raiser, the nuts often to the caller.
