Double Bonus pays two pair 1 instead of 2, and that single change guts what a kept pair is worth after the draw — the royal draw's 800-coin top end is untouched. So the same five cards split: on 9/6 Jacks or Better the pair of kings wins 1.5365 to 1.4884, and here the three-card royal wins by 0.0803. This is the line our own solver study found missing from the published 34-line Double Bonus charts; it holds for suited K-Q-J and Q-J-10, never for ace-high royal draws, and never when a four-card flush is in the hand.
Double Bonus chart line #8 of 36 — 'Suited Q-J-10 or K-Q-J: keep it even when one of those cards is paired (not with a 4-flush)' — sits above line #9, the high pair. See the full solver-optimized strategy chart, or drill hands with exact-EV feedback until plays like this are automatic.
