However, the old time players weren't too keen on the new-fangled way the kids were playing the game and it just didn't seem right if AAAA was not the best hand. The game evolved and straights, flushes, and straight flushes became widely accepted. This was because the straight and the flush (hence the straight flush) had not yet been invented. A long time ago, the best hand possible in poker was AAAAx or KKKKA.
