Who has the range advantage on T 9 8 rainbow?
Clear Button edge: the Big Blind has more open-ended draws, and the Button has nearly all the overpairs.
BTN vs BB single-raised pot: the button opens, the big blind calls.
medium / rainbow / connected
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.
Middle-card city. The button holds JT, T9, 98, and 76, while the big blind re-raises most of its suited versions and calls with offsuit broadways and one-gappers like 97 and 86 instead. The big blind ends up with more open-ended draws, the button with nearly all the overpairs, and the edge stays with the raiser.
