After the flop comes The Turn. One additional card is placed face up on the table next to the flop cards, as in the image above.
Now another round of betting takes place. As with the flop the player still in the hand and closest to the left of the dealer is the first to act. The rules of betting are exactly the same as on the flop.
Once all betting on the turn is complete we then move on to the final round of betting which happens on the river.
