Who has the range advantage on 7 7 7?

Small Button edge: the Big Blind has more sets, and the Button has more straights and better.

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

wet / rainbow / connected / paired

Button strong hands: 100.0% Big Blind strong hands: 100.0%

Share of each range that is sets, two pair, overpairs, straights or better, and combo draws. This is who wins the big pots.

Paired and even in nut hands: this flop misses both ranges. First aggression usually takes it. Try unpairing the board and see who the trips were protecting.

Every pocket pair is a full house and every unpaired hand is playing the board plus a kicker. The button's pair-heavy, big-card range makes it the favorite in a spot where almost nothing connects for anyone.
