Tonight, I made a major error while practising video poker. In 9/6 Jacks or Better, I held a low pair instead of four cards to a flush. this error would have cost me $46 per hour in expected value. It was a silly error, maybe because I was playing too fast. One way I can reduce the chances of this error happening is before drawing to a held low pair, take one last glance for flushes since the only starting hands in 9/6 Jacks or Better that are higher than a low pair are straights with four high cards, flushes, and three cards to a royal flush.
