Frame & Fork

A sparring app for sales conversations, built on the rails chess.com built for chess. 100 hand-authored puzzle positions across 7 themes (budget, procurement, stall, renewal, multi-stakeholder, endgame, cold open). Each position presents a buyer's line and four candidate moves. Pick one in 30 seconds. Reveal: each candidate's eval score, the mechanism the best move uses, the Atlas technique tag, and the linked transcript from a published practitioner. Daily Drill rotates a deterministic puzzle per date. Solve correctly and your streak compounds. 35 Atlas techniques across 8 clusters (question-form, framing, compliance, negotiation-anchor, structural-close, post-objection, closing-environment, Cialdini-six). Each lesson surfaces the move's mechanism, where it lands, and where it backfires, sourced from Voss, Klaff, Cialdini, Cardone, Tracy, Belfort. 5 annotated master games. Eval curve, per-move technique tags, master's commentary. Watch the move-by-move trajectory of a real closer's day, in the same format chess.com uses for Kasparov's games. Three rating buckets (Game / Puzzle / Analysis). Glicko-2 from Glickman 2013, same system chess.com uses for puzzles. Title progression from Patzer to Grandmaster Closer.
