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.
The textbook caller board, and the closest call on this list. The big blind has double the middle pairs and more open-ended draws, while the button leans on four times the overpairs and its big cards for a lead of about a point. When the big blind check-raises here, those overpairs are already sweating.
