Poker rules — hand rankings, betting rounds and casino poker variants

Poker splits into two categories that share a name and little else. Getting the distinction right matters more than any strategy tip.

Two different games

Player-versus-player poker — Texas Hold’em, Omaha, tournaments. You compete against other players. The casino takes a rake from the pot and has no stake in who wins. Skill determines results over time, and a strong player genuinely beats weak ones.

Casino poker — Caribbean Stud, Three Card Poker, Casino Hold’em, Ultimate Texas Hold’em. You play against the dealer with a fixed house edge, exactly like blackjack. No amount of skill makes these profitable; correct play only minimises the loss.

Both appear in an online casino lobby under “poker”. Only the first is a game you can beat.

Hand rankings

From strongest down. These apply almost universally:

1. Royal flush — A K Q J 10, same suit
2. Straight flush — five in sequence, same suit
3. Four of a kind
4. Full house — three of a kind plus a pair
5. Flush — five of a suit, not in sequence
6. Straight — five in sequence, mixed suits
7. Three of a kind
8. Two pair
9. One pair
10. High card

An ace plays high or low in a straight: A-2-3-4-5 is valid, and is the weakest straight.

A Texas Hold’em round

1. Preflop — each player receives two private cards; betting begins left of the big blind
2. Flop — three community cards are dealt face up; betting
3. Turn — a fourth community card; betting
4. River — a fifth community card; final betting
5. Showdown — best five-card hand from any combination of your two and the five community cards

You may use both, one, or neither of your private cards.

Position

Acting last in a betting round means seeing what everyone else did first. That information is worth more than most beginners believe — it is why identical cards are played differently from early and late position, and why “position” appears in every serious strategy discussion.

Casino poker variants

These have optimal strategies that reduce the edge but never remove it. The progressive side bets attached to them carry edges above 10%.

Bankroll and tilt

The two things that end poker players are playing stakes too high for the bankroll, and continuing after a bad beat. Neither is about cards. A standard guideline for cash games is at least 20 buy-ins for the level you play; tournaments need more, because variance is far higher.

Online-specific notes

Online play is faster than live, hands accumulate quickly, and multi-tabling multiplies both edge and mistakes. Note also that poker rooms are licensed separately from casinos in several African jurisdictions, and a casino licence does not automatically cover player-versus-player poker.
