Omaha (PLO) · a club for us and our friends

Learn Omaha on exact math

A school with lessons in order, a trainer with bots that play by the chart, practice with friends at one table and a review of the hands you've played. Every number is computed by the engine, not made up.

No passwords or sign-up, no money in the club. Login window won't open? Message the bot @showdownclubbot

Preflop by the 6-max 100 bb chart: a random hand and spot, the bots before you act as in the chart, graded by the chart frequencies. Five hands, no sign-in, preflop only.

Upload the hands you've played — we review every decision

And the trainer will drill exactly your mistakes: the same hands in the same spots until you play them right.

UploadDownload the hand history in your poker room and upload the files or a single .zip to the club — several rooms at once is fine. Only you see your hands.
Full reviewPreflop is checked against the 6-max 100 bb chart (heads-up — against the heads-up chart). After the flop — calls and folds against a bet, by the opponent's real cards once he showed them: equity, pot odds and how many bb the decision cost.
Drill your mistakesThe “Train my mistakes from hands” button: the trainer deals you your own hands in the same spots. A fixed mistake leaves the list.

We review Omaha cash games (PLO, PLO5, PLO6): GGPoker / PokerOK, PokerStars, ACR (WPN), 888poker, iPoker (Betfair, bet365, William Hill, Unibet…), Winamax, partypoker. Tournaments, Hi-Lo and Hold'em aren't reviewed yet.

We don't grade bets, checks and raises after the flop — only calls and folds against a bet.

Omaha is not hold'em with four cards

Hold'em intuition regularly fails in PLO. Here are four facts computed by our engine — each is covered in the school lessons.

50 / 50

Aces vs a rundown

Rainbow AA72 vs double-suited JT98 — 49.8% vs 50.2%. A pair of aces in Omaha is not “almost a win”.

54%

A draw beats a set

A 20-out wrap JT76 on a 9-8-2 flop is the favourite against a set of nines. And the nut flush draw against top set is only 30%.

68%

Someone already has the straight

On a 9-8-7 flop with two hearts at a six-handed table, at least one opponent already has a made straight in 68% of hands — and that's with random hands.

80 → 70

The “×4” rule lies

For 20 outs the rule promises 80% by the river, in reality it's 69.7%. On big wraps the error reaches 10%.

Frequently asked questions

What is PLO and how is it different from hold'em?

Pot-Limit Omaha is poker where everyone has four cards, and a hand is made from exactly two hole cards and three board cards. The bet is limited by the size of the pot. Hands are much closer in strength than in hold'em, so play after the flop decides.

How does the school work?

The entry test sets your level. Lessons go in order: the next opens once the previous is mastered (70%+). Each level ends with an exam (75%+), after which the next level opens and your rank grows.

Do I need Omaha experience?

No. The test will show your level, and your plan will start with what you really need — from the rules and pot limit to blockers and 4-bet pots.

Where do the correct answers come from?

Preflop — from the 6-max 100 bb chart (PL200 rake). After the flop our engine computes the answers — by exact enumeration of all card combinations or by a large sample — so every number in the puzzles and lessons can be checked.

How do I sign in, and do I need to register?

There is no registration: one-click sign-in with Telegram. We don't ask for a password, email or phone.

Can I use the site while playing for money?

No. Showdown Club is for learning and post-game review. Poker room rules forbid assistance during play.
