Eques and Knott are playing a game of standard 3x3 Noughts and Crosses. At no stage of the game has Eques threatened to complete a row of three on his very next turn.
Suddenly Knott realises he must lose. What is the position?

The position is as follows:
No two of Eques's counters occupy the same line of 3 (satisfying the never-threatening requirement), and no matter where Knott (O) places their next O, Eques (X) has a winning move whereby he sets himself up for two winning moves simultaneously - Knott is unable to block both on their next turn:
Assuming Eques plays optimally - and is actually trying his hardest to win - Knott must lose indeed!
