Course curriculum

• Lesson 1. Introduction to Five-Card Omaha

  To make a poker hand in PLO5, you must use exactly two of your hole cards and exactly three community cards — no more, no less.

• Lesson 2. Hand Rankings and Hand Strength

  Hand rankings in PLO5 are identical to Hold'em, but because players have more cards in hand, the nuts are formed more frequently — second-best hands lose more often.

• Lesson 3. Starting Hand Selection

  A strong starting hand in PLO5 is one where all five cards work together: connected by rank, by suit, or both. A single unrelated card — a dangler — sharply reduces the hand's value.

• Lesson 4. The Variety of Starting Hands and Equity

  In PLO5 there is no ready-made starting hand chart. Instead of memorizing lists, you need to understand the principles of hand evaluation and equity — the share of the pot a hand will win on average over many repetitions.

• Lesson 5. Pot-Limit and No-Limit

  Pot-limit caps the maximum bet at the size of the current pot — this makes the game more strategic and position-dependent. PLO5 is a pot-limit game by default (PLO = Pot-Limit Omaha).

• Lesson 6. Calculating the Pot-Limit Raise

  Maximum pot-limit raise = call + pot size after the call. Memorize this formula — it works in any situation at the table.

• Lesson 7. Playing the Flop: Board Textures

  Board texture describes how 'dangerous' a flop is: how many straight and flush draws it creates. The more draws on the board, the wetter the flop — and the more carefully you must play made hands.

• Lesson 8. The Importance of Position

  Position gives you information. Playing in position means making decisions after seeing your opponent act. In PLO5 this advantage is especially powerful because hand equities run so close.

• Lesson 9. Wrap Draw: The Big Straight Draw in PLO5

  A wrap draw is a straight draw with a very large number of outs (11–17+). It occurs when several ranks on the turn complete a straight through different pairs of your hole cards. The non-negotiable rule in PLO5: exactly 2 hole cards + exactly 3 board cards.

• Lesson 10. Flush Draws and the Nuts

  A nut flush draw (with the ace) is an aggressive asset. A non-nut flush draw is a potential trap. This distinction drives the entire flush draw strategy in PLO5.

• Lesson 11. Equity and Probabilities

  Equity is your mathematical share of the pot (chance to win + chance to split). Decisions should be based on comparing your equity to the cost of entering — not on the intuitive feeling of 'do I look strong?'

• Lesson 12. Counting Outs

  An out in PLO5 is only a card that, when it arrives, lets you build the required combination using exactly 2 cards from your hand + 3 from the board. Dirty, overlapping, and blocked outs must be filtered before making a decision.

• Lesson 13. Starting Hand Charts

  In PLO5 we value nut-potential, double-suitedness, and connectedness. Avoid domination: low flushes without the ace and low-end straights are traps — they look nice but regularly lose to the nuts.

• Lesson 14. Aggression and Pot Control

  Aggression builds pots with strong hands and high equity. Pot control protects from losses with vulnerable hands. The main question before every action: 'Do I want to play a big pot here?'

• Lesson 15. 3-Bet and 4-Bet in PLO5

  A 3-bet is a tool with a specific goal: value, isolation, or building initiative. A 4-bet is almost always a super-premium story and full pot commitment. Position and nut-potential determine which hands fit each.

• Lesson 16. Multiway Pots and Strategy

  A multiway pot automatically demands a nut-focused approach. Not the nuts — do not invest (with rare exceptions). Learn to fold decent but beatablehands when many players want the same pot.

• Lesson 17. Playing Against Short Stacks

  Against a short stack (less than 20BB) tighten your range and prepare for an all-in already on the flop or turn. Look for hands with good equity in all-in spots and do not put big money in with marginal hands.

• Lesson 18. Nuts vs Second Nuts

  The second nuts is a strong hand, but in large pots without blockers and redraws it often becomes a trap. Knowing when to fold 'almost the nuts' is the mark of a strong player.

• Lesson 19. Redraws and Freerolling

  A redraw is a backup path to improve if you get outdrawn. Freerolling is a situation where you split in the worst case but win everything in the best case. Look for both concepts in every hand.

• Lesson 20. Pot Control on the Turn and River

  Pot control is not passive play. It is the ability to make the pot match the strength and vulnerability of your hand. The more vulnerable your hand — the smaller the pot you need.

• Lesson 21. Bluffing and Semi-Bluffing in PLO5

  In PLO5 the foundation of aggression is the semi-bluff with a strong draw and blockers. Reserve pure bluffs for rare heads-up spots with a dry board and a clear folding range from the opponent.

• Lesson 22. Sets and Two Pairs in PLO5

  In PLO5 think not 'I have a set/two pair', but 'how nutty is this, how dangerous is the board, do I have blockers and redraws, and is my plan ready for the turn and river'.

• Lesson 23. Board Classification in PLO5

  Board classification is a skill that saves money. You assess: how many draws people have, how stable the nuts is, and how the situation changes on the turn and river.

• Lesson 24. Bankroll Management

  Your bankroll is a working tool, not 'money in an account'. Its job is to survive the inevitable swings and let you make correct decisions without fear.

• Lesson 25. Psychology and Tilt

  Tilt is the main enemy of long-term results in PLO5. You do not have to win every session. You have to maintain decision quality. Judge yourself not by the final sum but by how correct your decisions were.

• Lesson 26. Position on Late Streets

  In PLO5 position is not just convenience. It is a tool that provides information, controls pot size, increases value extraction, and reduces expensive mistakes. Sometimes the strongest decision in position is to not press the bet button.

• Lesson 27. PLO4 vs PLO5: What's Really Different

  PLO5 is not just PLO4 with one extra card. It is a different dynamic for pots, hand values, bankroll requirements, and psychology. Understanding the key differences helps you adapt faster and avoid costly mistakes when moving between formats.

• Lesson 28. PLO5 Starting Hands

  In PLO5 almost every hand has some potential — but winners are not those who 'see the flop often', but those who enter with hands that make the nuts, have redraws, and play well on later streets. What matters is not current strength, but hand structure.

• Lesson 29. Preflop in PLO5

  Preflop in PLO5 is the foundation of the whole hand. Five cards create an illusion of strength, but winners are those who enter with hands that make the nuts, have redraws, and realize well in position. The better your preflop, the easier the postflop and the fewer costly mistakes on turn and river.

• Lesson 30. Postflop in PLO5

  Postflop in PLO5 is where you either take the pot or give away your stack. 'Connecting with something' barely means 'I am ahead': everyone has 5 cards, draws are massive, nuts change fast. Postflop is not about emotions but about a plan: nuts, redraws, and correct decisions street by street.
