From 42e6e23900f07d9606c16bd787b2e853d7e0c93c Mon Sep 17 00:00:00 2001 From: prosolis <5590409+prosolis@users.noreply.github.com> Date: Sat, 18 Apr 2026 01:06:50 -0700 Subject: [PATCH] Overhaul hold'em tips: solver-backed scenarios, equity ranges, validation suite Replaces hardcoded tip scenarios with solver-frequency-backed decisions, adds equity range display, fixes bet-size matching tolerance (25% threshold), and adds comprehensive test coverage for scenario validation.

Position label is inverted in heads-up play + +The tip says "positional advantage" when the player is acting first post-flop (out of position) and "out of position" when they're acting last. The position label reaching the LLM prompt is wrong. + +**Root cause:** the `positionLabel()` function in `tips.go` derives position from `DealerIdx` using the general formula. In heads-up play the dealer posts the small blind and acts first pre-flop but **last** post-flop. The heads-up exception that exists in `PostBlinds()` in `betting.go` is not being reflected in position label calculation. + +**Fix:** in `positionLabel()`, gate on `len(g.Players) == 2` before applying any label logic. In heads-up: +- Pre-flop: dealer = BTN/SB (acts first), other player = BB (acts last) +- Post-flop: dealer = BTN (acts last, positional advantage), other player = BB (acts first, out of position) + +Check which street it is before assigning the label. `g.Street == PreFlop` needs different position semantics than all other streets in heads-up. + +--- + +### 2. LLM is generating generic concepts instead of hand-specific advice + +**Observed:** tips reference equity numbers but then ignore what those numbers mean for the specific hand. A player with 8♥ 7♥ on Q♥ K♠ 10♦ (gutshot + backdoor flush draw, 29% equity, free card available) received "not enough equity to bet" — which ignores the draw entirely and misapplies a made-hand concept to a drawing hand. + +**Root cause:** the user prompt is not giving the LLM enough structured context to reason about hand *type*. It sees an equity number but doesn't know whether the hand is a draw, a made hand, a bluff catcher, or air. It pattern-matches on the number alone. + +**Fix:** compute and inject the following additional fields into `TipContext` before building the prompt: + +```go +type TipContext struct { + // existing fields... + + // Add these: + HandCategory string // from poker.RankString() on current 5-card best + IsDraw bool // true if outs > 0 (see below) + FlushDrawOuts int // suited cards matching board suit count + StraightDrawOuts int // connected card gaps to straight + TotalOuts int // combined draw outs (deduped) + IsFreeCard bool // ToCall == 0 + HeadsUp bool // len(ActivePlayers) == 2 +} +``` + +Outs calculation (add to `equity.go` or a new `outs.go`): +- Flush draw: count hole cards matching dominant board suit; if 2 hole cards + 2 board cards same suit, FlushDrawOuts = 9 +- Open-ended straight draw: 8 outs +- Gutshot: 4 outs +- Backdoor draws: count as 1-2 outs each +- TotalOuts = sum, capped at 15 (avoid double-counting straights and flushes) + +--- + +### 3. System prompt needs to be more directive + +**Current system prompt** (paraphrased from blueprint): "be a concise Hold'em coach, 2-4 sentences, cover hand strength, pot odds, position." + +This is too open-ended. The LLM fills the space with whatever poker concepts come to mind. Replace with a prompt that forces it to reason about the specific situation before speaking. + +**New system prompt:** + +``` +You are a Texas Hold'em coach giving advice to a single player via private message. +You will receive structured game context. Reason through it in this order: + +1. What type of hand do I have — made hand, drawing hand, or air? +2. If drawing: how many outs, and do pot odds justify continuing? +3. If made hand: is it strong enough to bet for value, or weak enough to just pot control? +4. Does position affect what I should do here? +5. Is a free card available, and if so, is taking it correct? + +Then write ONE piece of advice — 2 to 3 sentences maximum — that tells the player +what to do and why, using the specific cards and numbers provided. +Do not list concepts. Do not use generic poker vocabulary without connecting it to +this specific hand. If the correct play is obvious (e.g. free card with a draw), +say so plainly and briefly. +``` + +--- + +### 4. User prompt needs draw and hand type context injected + +**Current user prompt structure** (from blueprint): +``` +Street: +Your hand: +Board: +Equity vs opponents: Win x% | Tie y% | Loss z% +Pot odds to call: x% +SPR: x | Position: | Active players: +``` + +**New user prompt structure** — add the computed fields: + +``` +Street: {street} +Your hand: {cards} [{hand_category}] +Board: {cards} +Draw outs: {total_outs} ({draw_description}) <- omit line if IsDraw == false +Equity vs {n} opponent(s): Win {x}% | Tie {y}% | Loss {z}% +{if ToCall > 0}: Pot odds to call: {pct}% — equity {exceeds|falls short of} price +{if IsFreeCard}: Free card available — no bet to call +SPR: {spr} | Position: {position} | Heads-up: {yes|no} | Street: {street} +``` + +`{draw_description}` examples: +- "flush draw (9 outs)" +- "gutshot straight draw (4 outs)" +- "open-ended straight draw (8 outs)" +- "flush draw + gutshot (11 outs)" +- "backdoor flush + backdoor straight (2 outs)" + +`{hand_category}` examples from `poker.RankString()`: +- "High Card", "One Pair", "Two Pair", "Three of a Kind", "Straight", "Flush", "Full House", "Four of a Kind", "Straight Flush" + +--- + +## Specific scenario the fix must handle correctly + +**Hand:** 8♥ 7♥ +**Board:** Q♥ K♠ 10♦ +**Street:** Flop +**Equity:** 29% +**To call:** €0 (free card) +**Position:** dealer, heads-up, acting first post-flop (out of position) + +Expected tip behaviour after fix: +- Identifies this as a drawing hand (gutshot + backdoor flush) +- Notes the free card is available +- Does NOT say "not enough equity to bet" without acknowledging the draw +- Does NOT say "positional advantage" — player is out of position post-flop heads-up +- Produces something like: "You have a gutshot straight draw with a backdoor flush. With a free card available you can check and see the turn without risk. If a 9 or a third heart comes, you'll be in a strong position — for now, take the free card." + +--- + +## Reasoning mode (Qwen3 thinking) + +Poker tips are the only task in GogoBee that should use reasoning mode. All other LLM calls (adventure narrative, etc.) run with thinking disabled. This needs to be a one-off configuration scoped entirely to `tips.go`. + +### Why reasoning mode here + +The tips failure pattern is not a knowledge gap — Qwen3-32B knows poker. The problem is that it jumps to pattern-matched conclusions without working through the situation in sequence. Reasoning mode forces the model to produce a `...` chain before the final response, which naturally surfaces: hand type, outs, position semantics, and the actual decision. The tip then follows from that chain rather than being assembled from disconnected concepts. + +### Request changes in `tips.go` + +Add a `enable_thinking` field to the request body and a `thinking_budget` cap to keep latency bounded: + +```go +type llmRequest struct { + Model string `json:"model"` + Messages []llmMessage `json:"messages"` + MaxTokens int `json:"max_tokens"` + Stream bool `json:"stream"` + EnableThinking bool `json:"enable_thinking,omitempty"` + ThinkingBudget int `json:"thinking_budget,omitempty"` +} +``` + +When building the tips request, set: + +```go +body := llmRequest{ + Model: cfg.Model, + Messages: []llmMessage{...}, + MaxTokens: 1000, // increased to accommodate think block + response + Stream: false, + EnableThinking: true, + ThinkingBudget: 512, // cap reasoning tokens; enough for poker, not runaway +} +``` + +`ThinkingBudget` of 512 tokens is sufficient for a poker hand analysis reasoning chain. Without a cap, complex board textures can produce very long think blocks. 512 keeps worst-case latency reasonable. + +Note: the exact field names for Ollama's Qwen3 thinking mode may differ from the above. Check the Ollama API docs for the current `qwen3:32b` thinking parameters — it may be `/think` appended to the model name (`qwen3:32b/think`) rather than a request body field, depending on the Ollama version. Either way, the intent is the same — make this configurable in `TipsConfig` so it can be toggled without a code change: + +```go +type TipsConfig struct { + Endpoint string + Model string + APIKey string + Timeout time.Duration + EnableThinking bool // default true for poker tips + ThinkingBudget int // default 512 +} +``` + +### Strip the think block from the response + +The `...` content must never reach the player DM. The current response parser takes `choices[0].message.content` directly.
