All For Nought v1.0.1

Added 16 Steam achievements, and a stronger AI on the higher difficulties.

Achievements (16)

• Difficulty milestones — Beat the AI on Easy, Normal, and Hard.
• Stalemate — Force a draw against the Expert AI. (See the AI section below.)
• Volume — 10 wins, 50 wins.
• Style achievements — Win on a diagonal, win straight through the middle, win without ever letting your opponent get two in a row.
• Each Way — Win along all 8 possible lines (3 rows, 3 columns, 2 diagonals) across any number of games.
• No Advantage — Win going second.
• Local play — Play 10 local-multiplayer games.
• Simulation — Watch the AI play itself, once and ten times.

Achievements track across sessions, so the longer counters tick along whether you're playing single-player, local multiplayer, or simulation mode.

Smarter AI on Hard and Expert

Hard and Expert now detect and block forks — situations where a single move would set up two winning threats at once. Previously, Expert was beatable with the classic corner / center / corner fork setup. That gap is closed.Practically:

• Expert — should now be effectively uncrackable with standard tactics. The best result a human can play for is a draw, which is exactly what the Stalemate achievement now rewards.
• Hard — meaningfully harder.

Have fun.
