1.1.0
- New: Exams & Survival Challenges — "Five Moves No Mistakes" and "Six Moves No Mistakes," a short, repeatable drill distinct from the full Opening Coach exams. The opponent opens with two fully random legal moves — genuinely anything, not just sensible theory — then plays its own best move from there on; your first several replies are graded on one running win-probability budget rather than a flat per-move cutoff, so the same size slip counts for less once the position is already decisive and for more in a close one.
- New: Show Best Move and Undo Last Move are both available mid-drill for exploration — using either during a graded move fails that attempt, but the board stays live afterward as free play so you can keep following the position out.
- New: an "Automatic Opponent Move" toggle for Opening Coach — turn it off to play a move on the opponent's behalf yourself (say, to see what happens if they grab a piece instead of finding the top engine reply) before handing control back.
- New: "Next Challenge" alongside "Try Again" on every drill — Try Again replays the identical opening you just saw; Next Challenge rolls a fresh one.
- Improved: several windows now remember their size and position between sessions.
- Fixed: a stray checkmate/stalemate marker no longer lingers on the board after taking a move back.
