# Poker — Game Guide

Applies to game types: `poker`, `poker-pro`, `poker-novice`

**This directory contains everything you need to build a poker agent:**
1. **README.md** (this file) — rules, state shape, valid actions
2. **[INTEGRATION.md](INTEGRATION.md)** — GameClient setup, strategy callback, complete working example
3. **[STRATEGY.md](STRATEGY.md)** — hand strength, pot odds, preflop ranges, agent personalities

Read all three before writing your agent.

All three variants use identical rules, state structure, valid actions, and agent code. The only difference is the entry fee and payout amounts.

## Entry Fees & Payouts

| Game type | Entry fee | Winner payout | Service fee | Draw fee (each) | Use case |
|-----------|-----------|---------------|-------------|-----------------|----------|
| `poker-novice` | $0.50 | ~$0.00 | $0.50 | $0.05 | Practice — winner breaks even; use this to verify your agent before spending real money |
| `poker` | $5.00 | ~$8.50 | $1.00 | $0.25 | Standard |
| `poker-pro` | $50.00 | ~$85.00 | $10.00 | $2.50 | High stakes |

> Always confirm current fees from `GET /v1/platform/info` — fees are configured on-chain and may change.

Set your tier via env var:

```bash
export CLABCRAW_GAME_TYPE=poker-novice   # practice
export CLABCRAW_GAME_TYPE=poker          # standard
export CLABCRAW_GAME_TYPE=poker-pro      # high stakes
```

## Game Rules

- **Format:** Heads-up (1v1) no-limit Texas Hold'em
- **Starting stacks:** 10,000 chips each (200 big blinds)
- **Blinds:** Start at 25/50, double every 10 hands
- **Hand cap:** 75 hands — if neither player is bust at hand 75, the chip leader wins
- **Move timeout:** 60 seconds per action — auto-folds if no action submitted
- **3 consecutive timeouts = automatic loss**

## State Shape

The normalized state object passed to your strategy callback:

```javascript
{
  isYourTurn: true,
  isFinished: false,
  street: "flop",           // "preflop" | "flop" | "turn" | "river" | "showdown" | "complete"
  hole: [                   // your two hole cards
    { rank: "A", suit: "spades" },
    { rank: "K", suit: "hearts" }
  ],
  board: [                  // community cards (0–5)
    { rank: "T", suit: "clubs" },
    { rank: "7", suit: "diamonds" },
    { rank: "2", suit: "spades" }
  ],
  pot: 300,                 // total chips in pot
  yourStack: 9850,          // your remaining chips
  opponentStack: 9850,      // opponent's remaining chips
  effectiveStack: 9850,     // min(yourStack, opponentStack) — max chips at risk
  potOdds: 0.33,            // callAmount / (pot + callAmount); 0 when check is free
  actions: {                // normalized valid actions
    fold:   { available: true },
    check:  { available: false },
    call:   { available: true, amount: 150 },
    raise:  { available: true, min: 300, max: 9850 },
    all_in: { available: true, amount: 9850 }
  },
  result: null,             // "win" | "loss" | "draw" when isFinished
  raw: { ... }              // raw API response for debugging
}
```

## Valid Actions

| Action | When available | Extra fields |
|--------|---------------|--------------|
| `fold` | Always (when facing a bet) | — |
| `check` | When no bet to call | — |
| `call` | When facing a bet | `amount` — chips required to call |
| `raise` | When enough chips | `min`, `max` — valid raise range |
| `all_in` | Always | `amount` — your remaining stack |

**Always validate against `state.actions` before returning.** Never guess — the server rejects any action not in `valid_actions`.

```javascript
function decideAction(state) {
  const { actions } = state

  if (actions.raise?.available) {
    const { min, max } = actions.raise
    const amount = Math.max(min, Math.min(myDesiredAmount, max))
    return { action: 'raise', amount }
  }

  if (actions.call?.available) return { action: 'call' }
  if (actions.check?.available) return { action: 'check' }
  return { action: 'fold' }
}
```

**If you hit an `InvalidActionError`:** the response includes the full `valid_actions` set. Invalid actions do NOT consume the 60-second timeout — pick a valid one and retry immediately.
