If player 2 calls, the bet stays the same, and player 3 then must either call, raise, or fold. Then, the player to their left, player 2, can do one of four things: check (unless player 1 bet, in which case player 2 must bet to stay in that round), call (match the bet in the pot), raise (bet more than the player before them), or fold (forfeit that round). Each player looks at their hand, and the player to the left of the dealer, player 1, can either check (bet nothing) or bet by putting money or chips into the pot.
Then, the dealer deals everyone 5 cards face down, one at a time. To play, first each player puts a predetermined ante into the pot, like 10 dollars. Five-Card Draw is a classic poker game where players try to create the best 5-card poker hand.
