Who has the range advantage on 9 8 7 rainbow?

Clear Button edge: the Button has nearly all the overcard hands, and the Big Blind has more gutshots.

BTN vs BB single-raised pot: the button opens, the big blind calls.

medium / rainbow / connected

Button: 54.2% Big Blind: 45.8%
Button strong hands: 14.2% Big Blind strong hands: 6.2%

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 has the edge on a draw-heavy board. Bet bigger with a tighter range and charge the draws. Try a high card in place of a connector and watch the board flip the Button's way.

Not the caller's parade it looks like. The big blind re-raises most of its suited connectors before the flop, so what it calls with here is mostly one-gappers, offsuit hands, and gutshots, while the button holds every overpair and the big-card hands. Those big pairs still need care on a board this connected.
