|---|---|---|
| Unlimited engine sparring | $0 free forever (including live move-by-move coaching) | Strict free trial / daily cap; recurring subscription required for regular sparring |

How depth-limited Stockfish 18 compares with cloud neural bots
Old chess programs weakened themselves clumsily by playing nine grandmaster moves and then tossing a queen away on move ten. Modern Stockfish 18’s UCI_Elo limits search depth and width instead, so a 1500 setting plays natural developing moves and overlooks three-ply tactical combinations — closely matching why club games are actually won and lost.
Because that search runs locally on your Apple Silicon Mac, iPad or iPhone in milliseconds, Brass Pawn never charges you monthly cloud GPU rent just to play a practice game.
Coaching while you play + Game Center when you want a real human
No bot — neural or classical — completely replaces human psychology on a clock. When you want true human unpredictability, Brass Pawn includes unlimited real-time Game Center matches on 3, 5, 10, 15 and 30-minute clocks at $0.
Honest boundaries
When Noctie AI is the better fit
- Noctie’s cloud neural networks are trained specifically on human game distributions (Maia-style) to mimic human opening/middlegame tendencies even more closely than depth-limited classical search.
- Noctie supports sparring from user-uploaded opening PGN repertoires in any browser (Windows, Android, Linux).
- Brass Pawn intentionally omits opening repertoire flashcards and requires iPhone, iPad or Mac.
Frequently asked questions
- Why can Brass Pawn offer free unlimited coached games while Noctie charges a SaaS fee?
- Every move Noctie plays or analyses runs on Noctie’s cloud servers, creating ongoing server cost per game. Brass Pawn compiles Stockfish 18 and Reckless 0.10 directly into your iPhone, iPad and Mac app, so computer games cost $0 to serve forever.
- Does Stockfish 18 in Brass Pawn just blunder pieces randomly at lower ratings?
- No. Brass Pawn uses Stockfish’s UCI_Elo search-depth and width limiting (from ~1400 to full strength), meaning the engine misses deeper tactical horizons rather than making absurd random giveaways.
- Can I start from a specific master game position in Brass Pawn?
- Yes — in Watch (900 decisive master games) or Today’s stories, you can tap Play on from here at any move to continue that exact position against the local engine with full coaching, or paste/photograph a position on the board.
- Does Brass Pawn work with zero internet?
- Yes. Every engine game, coaching note, tactic, positional drill, endgame drill and Watch game runs 100% offline.
