Practical game recognition vs composed textbook combinations
CT-ART earned its place in chess training history with dense, multi-variation combinational exercises and 5x5 hint boards. Where players sometimes stall is switching between five separate Chess King apps — one for beginner mates, one for CT-ART, one for strategy, one for endings — without ever playing a coached game that ties those muscles together.
Brass Pawn keeps all eight disciplines in one place on iPhone, iPad and Mac. Miss a deflection or quiet move in Tactics and spaced repetition brings it back; switch to Positional judgement when no forced win exists; then play a coached game against Stockfish 18 to test your blunder check under real move-by-move flow.
No DLC walls between chess skills
In Brass Pawn, tactics, positional exercises, endgames, Rush and Guess the Elo are never sold as separate expansion packs. Every mode opens for five daily attempts on the free tier, and one Pro purchase unlocks all of them.
Honest boundaries
When CT-ART / Chess King is the better fit
- CT-ART’s hand-curated Blokh combinations include simplified 5x5 visual hint boards for intermediate/advanced calculation.
- Chess King’s catalog includes niche single-opening and elementary checkmate workbooks, plus Android support.
- Brass Pawn’s endgame mode focuses on 15 core engine-verified drills rather than hundreds of composed endgame studies.
Frequently asked questions
- How does Brass Pawn verify that its puzzles are sound?
- The 14,185 imported Lichess puzzles undergo move-legality normalisation and MultiPV spot-checking, while the 166 locally mined puzzles are searched at depth 20 (requiring ≥140 cp margin over the second-best move) and independently re-verified by a separate script at higher depth.
- Does Brass Pawn offer hints when I get stuck?
- In Play & Coach games, Brass Pawn includes a two-step hint system — first highlighting candidate pieces, then showing the move arrow — plus take-backs. In Tactics, you commit to your calculated move on the board and get an immediate verdict plus spaced-repetition follow-up if you miss.
- Are quiet moves included in Brass Pawn’s tactics library?
- Yes — 1,101 puzzles in Brass Pawn’s bundled library specifically turn on a quiet move (not a check, not a capture, not an immediate mate threat), alongside 1,318 sacrifices and 646 deflections.
- Do I have to pay separately for iPad and Mac?
- No. Brass Pawn is one universal App Store app across iPhone, iPad and Mac.
