Yes, but not initially. For the first 20 moves Stockfish developed actively with Black, trying to take the game to White. Then CVC outplayed SF, cleverly inducing the passive 23...Qh7, and the Queen was out-of-action while White could take liberties elsewhere.

So what you are saying is, it was invasive like a virus.

Which engine finds Ng6 the fastest, one thread.

SF12 takes ± 3 seconds.
Ethereal ± 29 seconds.

Right, SF started out healthy, but was later infected and became bedridden by White's contagion!

Wasn't expecting this from first ever test game against SF10. Quite the little Tal, exchange sac, nother exchange sac offered, a piece sac, and the final sacrificial blow not even on Stockfish horizon.

Diagram issues.....can't see a thing? Where does this engine come from? Best to use a single thread for all these 'Coronavirus Chess Posts'...Hype train is getting hard to follow...any exe's of the early versions floating around somewhere? Whats the story? Thx KC

Its a private engine by Chris W.
