# ChessAgine MCP Skill v0.6.3 (chessagine-mcp-v060)

ChessAgine provides comprehensive chess analysis through 40+ specialized tools integrating Stockfish, Leela Chess Zero, Maia2, Lichess, Chessboard Magic, and multiple chess databases. v0.6.3 adds Chess 960 support, theme analysis tools, game review generation, and tactical summaries.

## Core Workflow Principles

### Context Priority
When handling chess requests, always:
1. First consult this chessagine skill for chess-specific context, tools, and workflows
2. Then reference user's project memory related to chess for personalized preferences or context

### Always Visualize
Every position analysis must include visualization using the correct MCP rendering tools:
- **Single positions**: Use `chessagine-mcp-v0.6.3:render_chess_board` with FEN
- **Full games**: Use `chessagine-mcp-v0.6.3:render_pgn_viewer` with PGN

### Chess 960 / Fischer Random Support
Many tools now accept an `is960: boolean` parameter (default: false). Pass `is960: true` when:
- User mentions Chess 960, Fischer Random, or FRC
- FEN has non-standard castling rights (e.g., HAha instead of KQkq)
- User explicitly mentions a randomized starting position

Tools supporting `is960`: `get-boardstate-for-fen`, `get-boardstate-for-move`, `is-legal-move`, `get-theme-scores`, `get-theme-progression`, `analyze-variation-themes`, `compare-variations`, `find-critical-moments`, `generate-game-review`

### Multi-Source Validation
For important positions, combine multiple data sources:
- Opening database (fast orientation)
- Engine analysis (best moves)
- Master games (practical validation)
- TCEC/Correspondence (computer/deep human perspective)

### Right Engine for the Job
- **Stockfish** (depth 18-25): Best objective moves through brute-force calculation
- **Elite Leela**: Master-level human perspective (~2500 rating) for strategic insights
- **Leela**: Neural network for positional understanding
- **Maia2** (rating 1100-1900): Human-like moves matching specific player strengths

### Progressive Depth
Start with quick overview, deepen analysis only where critical:
- Quick check: depth 15-18
- Standard analysis: depth 20-22
- Critical positions: depth 25-30

## Quick Start Workflows

### Analyze Position
1. `chessagine-mcp-v0.6.3:get-boardstate-for-fen` (understand position)
2. `chessagine-mcp-v0.6.3:render_chess_board` (visualize)
3. `chessagine-mcp-v0.6.3:get-stockfish-multipv-analysis` (3 lines, depth 22)
4. `chessagine-mcp-v0.6.3:fen-openingbook-lookup` (if opening)
5. `chessagine-mcp-v0.6.3:get-lichess-master-games` (master practice)
6. `chessagine-mcp-v0.6.3:get-theme-scores` (optional: material, space, king safety breakdown)

### Analyze Game (Quick)
1. `chessagine-mcp-v0.6.3:fetch-lichess-game` (get PGN) or accept user PGN
2. `chessagine-mcp-v0.6.3:generate-game-review` (comprehensive theme review with critical moments)
3. `chessagine-mcp-v0.6.3:render_pgn_viewer` (navigable game view)

### Analyze Game (Deep)
1. `chessagine-mcp-v0.6.3:fetch-lichess-game` (get PGN)
2. `chessagine-mcp-v0.6.3:parse-pgn-into-fens` (extract positions)
3. `chessagine-mcp-v0.6.3:find-critical-moments` (identify key turning points)
4. `chessagine-mcp-v0.6.3:get-stockfish-analysis` on critical positions (depth 20)
5. `chessagine-mcp-v0.6.3:render_pgn_viewer` (navigable game view)

### Study Opening
1. `chessagine-mcp-v0.6.3:fen-openingbook-lookup` (identify opening, common moves)
2. `chessagine-mcp-v0.6.3:get-lichess-master-games` (master statistics)
3. `chessagine-mcp-v0.6.3:get-chessboardmagic-tcec-stats` (computer evaluation)
4. `chessagine-mcp-v0.6.3:get-stockfish-multipv-analysis` (5 lines, depth 25)
5. Fetch sample games from relevant database

### Find Best Move
1. `chessagine-mcp-v0.6.3:get-stockfish-best-move` (tactical solution)
2. `chessagine-mcp-v0.6.3:get-stockfish-multipv-analysis` (alternatives, 3 lines)
3. Cross-reference with `chessagine-mcp-v0.6.3:get-chessdb-analysis`
4. Optionally add `chessagine-mcp-v0.6.3:get-chessdb-pv` for engine best line from ChessDB

### Compare Variations
1. `chessagine-mcp-v0.6.3:compare-variations` (pass rootFen + named variation arrays)
2. Interpret theme scores per variation (material, mobility, space, positional, kingSafety, tactical)
3. `chessagine-mcp-v0.6.3:render_chess_board` on key resulting positions

### Puzzle Training
1. `chessagine-mcp-v0.6.3:get-puzzle-themes` (show available themes)
2. `chessagine-mcp-v0.6.3:fetch-chess-puzzle` (with theme/rating filters)
3. `chessagine-mcp-v0.6.3:render_chess_board` (present)
4. After attempt: `chessagine-mcp-v0.6.3:get-stockfish-best-move` (verify)

### Chess 960 Analysis
1. Confirm `is960: true` for all supporting tool calls
2. `chessagine-mcp-v0.6.3:get-boardstate-for-fen` with `is960: true`
3. `chessagine-mcp-v0.6.3:render_chess_board` (visualization works for all variants)
4. `chessagine-mcp-v0.6.3:get-stockfish-multipv-analysis` (Stockfish handles 960 natively)
5. Note: Opening book and master game databases are standard chess only — skip for 960

## Common Request Patterns

| User Request | Workflow |
|--------------|----------|
| "Analyze this position [FEN]" | Position Deep Dive (see references/workflow_patterns.md) |
| "Analyze my last game" | Get Lichess username → Fetch recent games → `generate-game-review` |
| "What's the best move?" | Quick best move + alternatives + explanation |
| "Help me study the Sicilian" | Opening study workflow with multiple databases |
| "I'm stuck in this endgame" | Endgame analysis + `get-tactical-position-summary` |
| Lichess URL provided | Parse game ID → `fetch-lichess-game` → `generate-game-review` |
| "Give me a tactics puzzle" | Puzzle training session with explanations |
| "Chess 960 / Fischer Random position" | All analysis with `is960: true` |
| "Compare these two variations" | `compare-variations` → theme breakdown |
| "When did the game turn?" | `find-critical-moments` on game variation |
| "How is my king safety?" | `get-theme-scores` → kingSafety reading |

## Advanced Features

For detailed guidance on:
- **Workflow patterns**: See [references/workflow_patterns.md](references/workflow_patterns.md)
- **Tool selection**: See [references/tool_selection.md](references/tool_selection.md)
- **API parameters**: See [references/api_reference.md](references/api_reference.md)
- **Chess knowledge**: See [references/chess_knowledgebase.md](references/chess_knowledgebase.md)

## Best Practices

### Performance Optimization
- Use `generate-game-review` for fast comprehensive game analysis (replaces manual parse → batch analyze)
- Use `find-critical-moments` to identify key positions before deep diving
- Use batch analysis for 10+ positions
- Start with opening book (fastest) before databases
- Use `get-chessdb-pv` for quick best line before committing to deep Stockfish search

### User Experience
- Always visualize positions using MCP rendering tools
- Explain evaluations in chess terms (not just numbers)
- Match analysis depth to user expertise
- For theme scores: positive = White better, negative = Black better, zero = equal

### Error Handling
- **Retry Logic**: If any tool call returns an error, automatically retry up to 2 times before informing the user
- On third failure: Clearly inform user that the tool encountered an error, specify which tool failed, and suggest alternatives when available
- Validate FEN format before tool calls
- Check move legality with `is-legal-move` before analysis
- Graceful fallbacks: book → ChessDB → Lichess → TCEC
- Handle missing user accounts gracefully
- For Chess 960: skip opening book and master game lookups (databases are standard chess only)

## Key Reminders

- **MCP version**: All tool calls use prefix `chessagine-mcp-v0.6.3:` (not v0.6.0)
- **Chess 960**: Pass `is960: true` on all supporting tools for Fischer Random positions
- **New theme tools**: Use `generate-game-review` for fast game analysis; `get-theme-scores` / `compare-variations` for strategic breakdown
- **Retry on errors**: Retry failed tool calls up to 2 times; inform user only after 3rd failure
- **Always visualize**: Use `render_chess_board` for positions, `render_pgn_viewer` for games
- **FEN validation**: Check format before API calls
- **Progressive detail**: Quick overview → selective deep dive
- **Multi-source**: Combine engines, databases, and principles
- **User-focused**: Match analysis to user's needs and skill level
