I really need to work. I've done nothing today except the washing and making coffee and tea for my wife, oh, and talking to the next door neighbour for an hour. She's autistic, apparently, and her younger daughter very much more severely so.
I have really got to make eleven more philatelic auction lots and I'm expecting a visitor in an hour and a half so please excuse me if I call this a day here. I'm not going to make any progress with the others here but please do be aware that tygxc isn't all wrong. They deliberately misrepresent him and he's too proud to show too much concern, which I respect. All the best.
Well, yes I'm merely using tygxc's term for ease of conversation ...
In this case, SF 16.1 found a sequence of moves that pushed the evaluation to +1.5 in White's favor, after a few moves ... in terms of engine play, I'd consider any move or sequence that allows a +1 or -1 change in eval to be a "mistake" (or "error", or whatever term we prefer ...).
But yes, in terms of human chess, I agree that we can sometimes call dubious moves "brilliant" for their impact on the game - especially if they give the opponent a hard time, despite not being the best.
Yes ok, I personally don't like the idea that a blunder is different from an error because it's win to loss. But it makes sense to use ty's terminology. Thanks for clarifying.
