Your first invitation

Read your made hand and the public boards together. The changing exposed cards make memory part of the game.

Begin with two private cards and one exposed card. Fourth, fifth, and sixth streets add exposed cards; seventh adds a private card. Your best five-card high hand wins. The lowest opening door card brings in, and later streets start with the strongest exposed high hand.

Take your seat with Fern and familiar AI company. The room offers heads-up or six-seat play, automatic next hands, adjustable pace, practice peeks, a visible WSRF tree, a Monte Carlo playground, and a notebook that keeps your place. Choose Gentle company while learning the rhythm, then explore Seasoned or Sharp whenever you feel ready.

Start by naming the game and the legal five-card construction. Then count the players still active and read the amount needed to continue. Those small observations give the coach’s estimate a useful setting. The worked pages that follow preserve their cards, assumptions, and numerical receipts so you can explore the same question again.

A rhythm you can follow

The room keeps the chip arithmetic close to the action.

At this tableHow it works
Starting stack2,000 free play chips at each seat
SeatsHeads-up or six seats
Blinds / antesAnte up to 2 per seat; bring-in up to 5
BettingSmall increment 20; large increment 40.
Street rhythm20 on third/fourth; 40 on fifth/sixth/seventh
Limit capFour full bets per street, including the opening bet.
Short all-insA full increment reopens raising under this room’s house rule.
Split-chip orderThe high half receives an odd split chip. Tied shares award odd chips clockwise from the stored button.

These are the room’s declared house settings. A short stack contributes its available chips, and side pots keep each contribution matched to the players eligible for it. A returned unmatched contribution stays separate from a contested pot. Opening the Coach or Options panel holds the action while you explore.

A bring-in can be completed to the full 20-chip small bet. Completing it reopens action to the players who entered below that amount. An exposed pair on fourth street also makes the larger 40-chip option available.

See the five-card construction

The cards make the idea concrete.

A♣A♦A♥7♠7♣K♦Q♥

Seven personal cards offer twenty-one five-card selections. The evaluator chooses the strongest legal high hand, and the split game also finds the best qualifying low. A card outside the final five can still have helped tell the story on an earlier street.

Try covering the worked answer and pointing to the five chosen cards. Then name one different final card that would invite a new construction. A concrete card change is a useful way to connect imagination with the rules.

A little map of possibility

One away, two away, three away—and a clear reference frame.

23456789TJQKA✦DISTANCE MAP

LIKELY · 8/13 near ranks

Moving references: 3 · J · Q · T

48 unseen cards.
Bucket counts: 13 / 15 / 12 / 8

Distance mean 1.31 · SD 1.04

The pocket map uses your first two dealt cards. In an Omaha hand these are an explicit pair of anchors inside the four-card pocket; the hand evaluator still explores all legal two-card choices. In a stud hand they are the first two private cards. The moving map uses the latest two community cards or your latest two exposed stud cards once they are available.

The map’s circular ranks run from 2=0 to A=12. The reference expressions use the two anchors, their sum modulo thirteen, and their absolute difference. Near means distance zero or one. Seven or more near ranks gives LIKELY; six or fewer gives UNLIKELY. Both labels receive balanced examples in each newly trained model.

Known-card counts include your own cards and every publicly exposed card, including cards shown by a folded stud opponent. That keeps the remaining physical-card counts connected to what you can actually observe. The game-specific hand ranking and the map each describe their own part of the hand.

A few habits worth keeping

Let the game’s special character guide your attention.

A personal board has a voice

Each opponent develops a separate exposed board. Compare those boards with your own made hand. A paired door board tells a different story from four connected ranks or several matching suits. Begin by describing what is visible, then use your private cards to understand what your own hand adds.

Remember the cards that passed through

A folded player’s exposed cards still belong to the public story. They remain known cards for the next-card sampler. If you are studying a suit draw, count the visible cards of that suit before considering the remaining deck. This is a practical way to connect attention with the arithmetic.

Fourth street offers a special choice

At this Stud-high table, an exposed pair on fourth street opens the option of a 40-chip bet or raise while the usual small amount is 20. Choosing the larger increment makes the rest of that street use 40. The available buttons show the legal choices, so you can explore the effect of the bigger decision.

A private seventh card adds a final discovery

Your last personal card arrives face-down. It can complete a construction while leaving the visible board unchanged for everyone else. The coach knows your own new card and the other exposed cards. That information boundary is what makes the final estimate a useful companion to your decision.

This independently generated teaching hand preserves your own cards and every exposed card, then samples the remaining cards uniformly. Fractional ties and split pots contribute the share actually earned. The interval describes sampling uncertainty under that model; the forest’s estimate is a separate learned prediction.

Compare the action scores with the call price and the active field. They express the explicit betting policy’s use of the learned share, rather than a fitted chip-return forecast. Opening a tree lets you follow the card features that helped produce the share estimate.

Each game receives 6,144 training positions, with 128 independently sampled showdowns at every position. Six equally represented pools combine opening, middle, and closing play with LIKELY and UNLIKELY moving-map labels. Private and public suit counts, exposed-board strength, and rank geometry give the forest a richer view. The fitted object is pytoolzx.wsrf.WSRFRegressor, and pytoolzx.indexrng.Index supplies independently named seed streams.

Compact and full forests are compared on 768 validation positions. The smaller validation error chooses the serving forest before a fresh 1,536-position test is evaluated. Validation labels use 384 samples; test labels use 512. MAE is the average absolute difference in estimated pot share, expressed here in percentage points.

The complete-hand benchmark rotates the trained policy through every seat of each fresh deck. Its intervals use deck averages to respect the relationship between seat rotations. These named local practice styles define the scope of the measurements. The full receipt preserves every game, table size, and opponent row.

Seven LanternsPractice

Practice

Make the table your own

A practice path you can enjoy returning to.

Begin with a comfortable rhythm

Choose Gentle company and a relaxed pace. Leave automatic next hands enabled if you enjoy a continuous session, or choose each new hand yourself. The panel controls hold your exact place whenever you open an explanation.

Give one hand a question

Choose a question you can inspect: can this card complete the construction, can this price be expressed as a pot share, or can the tree show which input it used? The worked answer becomes useful when you can point to its reason on the table.

Explore with a practice peek

A peek makes the opposing cards visible for your exercise. The model continues to use its own cards and public observations, so its estimate stays comparable before and after your peek. The notebook marks that hand as practice and preserves the result.

Let the forest take a turn

The WSRF partner option lets the trained adviser play your seat using the explicit betting policy. Pause on a street that interests you and open the tree. Watch mode is a way to explore the model’s choices; your own chair is ready whenever you switch back.

Keep a story to return to

Download a notebook from Options. It includes the deal and action sequence needed for exact replay, along with stacks, funding, completed hands, and HUD totals. Restore it in the same game and table size. A saved story can make the next visit feel like a continuation.
