Who has the range advantage on K Q J rainbow?
Big Button edge: the Big Blind arrives with more air, and the Big Blind has more bottom pairs.
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.
Still broadway, still the raiser's board, but the big blind sneaks back in with T9 and A-T type hands that make straights the button has to respect. Strong edge, real trapdoors.
