It was of course the "Q5T"-version of Junior. I can come to no other conclusion.
Until we see definite proof otherwise, only an engine tuned to the precise
Q5T-principles can make this kind of move. We demand to see the Junior logs!

-0.28 is from Black's viewpoint here.

It took a long time to resolve the fail-high at 14.01 (20 hours plus). At one
moment even the clock stopped, and I had to give it a kick to get the engine
running again. I think this is a sign of emerging intelligence in Q5T-Rebel,
soon it will only want to play Blitz.
