One game of Texas hold'em followed from the deal to the finish, move by move, with the reason for each choice.
Four players — you, Ada, Bo and Cleo — each start with 200 chips, and the blinds are 1 and 2. You have the dealer button this hand, so Ada, on your left, posts the small blind of 1 and Bo posts the big blind of 2. Before the flop the betting starts with the player after the big blind, which is Cleo, and goes round to Bo last.
Everyone is dealt two cards face down. Yours are A♥ Q♥: an ace and a queen of the same suit, a strong starting hand, and you will be acting last on every round after the flop.
Cleo folds. You raise to 6 — three times the big blind is a normal raise, and raising rather than calling gives you a chance to win the blinds straight away and cuts down the number of opponents. Ada folds her small blind. Bo calls the 4 more it costs him to stay in.
The pot is now 13: your 6, Bo's 6 and Ada's 1. Two players are left, and Bo will act first on every round from here.
Three cards are turned face up in the middle. You now have a pair of queens with an ace beside it — top pair, best kicker — and two hearts on the board to go with your two, so one more heart gives you a flush.
Bo checks. You bet 7, about half the pot: enough to be paid by a worse queen or a nine, and a price that does not give away how much you like the hand. Bo calls. The pot is 27.
The fourth card changes nothing for either of you. This time Bo bets first, 15 into the pot of 27. You still have top pair with the best kicker and nine hearts left in the deck to make your flush, so folding would be far too cautious — but raising would only fold out the hands you beat.
You call 15. The pot is 57, and both of you have 172 chips left.
The last card is the heart you wanted. Your best five cards are now A♥ K♥ Q♥ 9♥ 4♥, an ace-high flush. With no pair on the board nobody can have a full house, and no two cards make a straight flush with these, so your hand cannot be beaten.
Bo bets 20. You raise to 70, and Bo calls the extra 50. At the showdown Bo turns over K♣ Q♦ — the king on the river gave him two pair, kings and queens, which is why he kept betting. Your flush beats his two pair, and you win the pot of 197. You finish the hand with 299 chips, Bo with 102.
Every chip went in for a reason: a raise before the flop with a good hand from late position, a half-pot bet with top pair and a draw, a call on the turn at a fair price, and a raise on the river with a hand that could not lose. Acting last let you see Bo's decision before making each of yours.
It also shows how a hand is read: your two cards and the five on the board make seven, and your hand is the best five of them. Bo's two pair used both his own cards; your flush used both of yours and three from the board.
