Poker is about winning as many chips as you can. You win by making smart bets and/or having the best 5 card hand.
Hands are listed from best to worst. If players have none of these hands, then the winner with the highest card is selected.
Each player is dealt 2 face down cards called hole cards.
Five community cards are dealt in the center.
Community cards are shared, hole cards are not.
Only you can see your hole cards.
Using the community cards and YOUR hole cards, you will play the best five cards.
In this case, you have three of a kind.
As you can see, you do not need to use all or any of your hole cards.
