Why
In the BB facing a BTN open with Q9s, you are getting a great price closing the action, and the BTN raising range is so wide HU that Q9s is comfortably above average in equity. Suitedness adds flush and straight potential plus clean equity realization, so flatting to keep the BTN range wide and contest a flop where you hold range and nut advantage is the GTO baseline. A 3‑bet is a fine mix at times, but flatting captures the most EV with a hand this playable.
Key idea
HU the BTN opens up to 100 percent, so a suited two-broadway-ish hand like Q9s is far stronger relatively than it would be at a full table. Default to flatting playable suited hands in the BB to defend wide and realize equity on the flop.
Common mistake
Folding Q9s in the BB because it looks unremarkable. Against a near-100 percent BTN range, folding here burns clear EV; you are priced in and your hand plays well postflop.
