Amir Ban: "Towards the end, Junior itself was getting the hiccups. At move 64,
instead of playing the winning Bc5, it started dancing around the position. My
guess was that it was looking at 64. Bc5 g6 65. hxg6 Kg7 66. e7 Kxg6 67. e8=Q+
Bxe8 68. Kxe8 Kg5 and evaluating it as less than +3 at a distance (though this
is an easy win up close), hence the fudging."

Maybe you're correct Edward, but it's moot now. But indeed if there is a _bug_
J7 then it needs correcting.
