...playing against the old OXO robot using the Lambit Technique (Look it up).
That's
Lamkin. ;~>
And, yeah, that was probably a bug. A while back someone posted
something similar, having to do with having placed 6 of their pieces in a row and the game not registering that as a "win".
But I mucked up, placing the second loop 1 square away instead of two....
And that's probably what caused it.
On your next go around did you apply Lamkin's solution successfully?
