Touch-first clarity vs dense database controls
Chess Tempo was designed by and for players who love tables of percentiles, custom tag filters and PGN repertoire trees in a desktop browser. On a phone screen, that density can turn a quick ten-minute tactical session into squinting at menus and waiting on network requests.
Brass Pawn strips away configuration overhead on iPhone, iPad and Mac. Open Tactics and solve immediately with spaced repetition already wired in; open Positional judgement to assess quiet structures; or open Watch to take over one of 900 decisive master games against Stockfish 18.
Why Brass Pawn puzzles never branch ambiguously
Nothing erodes trust in a puzzle trainer faster than playing a winning move that happens not to be the author’s pet line. Brass Pawn’s puzzle pipeline extends each line only while the solver’s best move stays uniquely best (with a ≥140 centipawn margin at depth 20 on mined positions), stopping the puzzle the instant two moves are equally good.
Honest boundaries
When Chess Tempo is the better fit
- Chess Tempo supports custom Boolean problem sets, community problem comments and full opening repertoire trees that Brass Pawn does not offer.
- Chess Tempo works on Windows, Linux and Android browsers; Brass Pawn’s native app is for iPhone, iPad and Mac.
- Chess Tempo’s mixed mode mixes defensive non-losing positions directly into tactics, whereas Brass Pawn separates forced wins (Tactics) from quiet evaluations (Positional judgement).
Frequently asked questions
- How many tactical motifs does Brass Pawn track compared with Chess Tempo tags?
- Brass Pawn tags its 14,351 puzzles across 20 core tactical motifs — including fork (1,799), sacrifice (1,318), advanced pawn (1,129), quiet move (1,101), pin (1,074), discovered attack (798), attraction (675) and deflection (646) — so weakness reports stay actionable rather than split across hundreds of micro-tags.
- Does Brass Pawn have an equivalent to Chess Tempo’s Guess the Move?
- Brass Pawn approaches game study from two angles: Watch lets you step through 900 decisive master games and take over any position against Stockfish 18 when you disagree with a move, while Guess the Elo tests your ability to read playing strength across 1,624 rated games.
- Can I use Brass Pawn offline without a paid subscription?
- Yes. Free-tier engine games, Watch games and your 5 daily attempts per training mode all run offline on your device.
- Is spaced repetition locked behind Pro in Brass Pawn?
- No. Spaced repetition and per-discipline ratings work identically on the free tier; Pro simply removes the 5-a-day counter.
