Why this works
Proof-Built Puzzles in ChessHole are not about checkmate. They are about move order, reachable squares, and keeping a piece alive after the board changes.

Proof-Built Puzzles relaxing focus for daily solvers
Play without a timer and think through the board at your own pace. ChessHole helps daily solvers play boards designed to have a solution path while practicing generated challenges with solvability checks.
Play ChessHoleBest first habit
Before moving, count the safe landing squares each piece will still have after its current tile collapses. That single habit prevents most early dead ends.
