Should You Break a Flush to Go for a Royal Flush?
Dealt: K♥ Q♥ J♥ 10♥ 3♥
Best play: Hold K♥ Q♥ J♥ 10♥.

It feels wrong to throw away a paying flush, but four to a royal is worth over three times as much. The 800-for-1 royal dominates, and several draws (the 9 for a straight flush, any other suited card) still pay.
