If there was no low hand and you won the pot then you must of had a better hi hand than your opponent
for a low to be possible there needs to be 3 or more independant cards 8 or lower on the board, and these 3 cards must be different than the two you hold in your hand.
IE if board comes 456KK and you ave A4QQ you do not have a low hand
Okay, thanks for that, I must have looked a real mug to everyone else at the table then.
