For instance, Player A hits a Flush with cards, Kc,Jc,7c,2c,5c and Player B also gets another flush with cards Jh, 10h,6h,2h,9h. K and J are the Kicker cards poker here. Since Player A has a flush with a card of higher value that is K compared to player B whose highest card is J, player A wins the hand.
