Winning after Qf6+!

[Spliffjiffer]

yes, sure i have some variations stored...to provide a clear.pgn though i would need some hours to collect the stuff...if u have a specific question though i should be able to help probably without much trouble id suppose but of course: certain is nothing ...concerning the Bd2-line though (instead of Ng5?!) i just provided the exact same line one year ago (original thread) as Louis' SF.dev nowadays and i have no further insight there !

[jp]

So does this mean you are better than SF-dev?

[Spliffjiffer]

...no...if i remember well i analysed this Bd2 line with SF.dev from 1 year ago !...so nothing special ...ok, i did some forward, backward and choose probably a "most-human" line from my pov but the first moves (if i remember well) are pretty much forced (with filled hash-tables SF gave quite significant worse evaluations for other moves than Qa5!? , after Bd2, so i gave Qa5 the shot and i think its pretty much forced after that but not sure anymore)...actually i did not spend much time into Bd2 (instead of Ng5) because at this time the the main discussion was about "is Ng5 really winning if i play this or that" and i had much trouble to come to a conclusion !..no, im not better than SF, im a bad player for sure but i know how to use (different) engines after many years of practice

Well, the human POV is interesting, because I believe all reasonable humans will think about Qf6+, but humans will also all want to follow up with Ng5. So when an engine gives Qf6+ and Ng5(?), it's not so great from a human POV.

I confused this position with Arasan 132 with same kind of queen sacrifice :

[d]r2q1r2/1b2bpkp/p3p1p1/2ppP1P1/7R/1PN1BQR1/1PP2P1P/4K3 w - - 0 1
Much easier, but not trivial!

Can u give the pgn of all the winning lines? I am not getting the results as discussed. hence I will be analyzing deeply now.

I don't have any pgn files. Others do.

From the original position, here is a PV that might to be winning. You could start with this and either refute or improve it!

ya sure I will. But your pgn is not compatible to copy paste

Because it's not a pgn. It's raw output from Stockfish.

Depends on the GUI. IN chessbase and Aquarium output is not like that notation.
