On the tail end of a heads-up pot to the A♥8♥6♦Q♣4♥ river, Brad Ruben was about to expose his cards when Andrew Brown insisted he had raised a bet. Ruben called and the cards were flipped over.
Brown's 5♥4♣3♦2♥ were the nut low and a flush but it only got a quarter of the pot, as Ruben had the J♣J♥3♥2♣.
