It's a close call, but the Dancer Pro-Strategy for Double Bonus (my game) would hold the 3 card royal-flush over the pair of face cards if the RF 3 is either QJT or KQJ. These very fine points of the strategy are why I carry a pocket card to check on the tough calls.

Your strategy is the correct one, Kerry, for 9/6 Jacks or Better (no bonus).
