I guess 2200 players should respect 3000 ones more, but maybe your family did not teach you that. It's not my fault.
These statements are not worthy of respect.
Everybody, but everybody aside you on this forum knows I am the world's best chess theoretician.
If this was true, there would be no need to make the statement.

Re: Stockfish and Fischer

Post by Lyudmil Tsvetkov »

And here my latest puzzle for you from Fischer's positional suite:

[d]3r1rk1/1p1n1ppp/pNbpp3/8/2P1P3/5P2/PPB3PP/2RR2K1 w - - 0 19

White to play and win, single winning move.
This is from Fischer-Rossetto, Mar del Plata 1959.

Anyone able to find it?

Engines are reputed to be very good in the endgame, due to diminishing number of lines.
Do the 64/16 cores see it?

Adam, are you reading the whole thread, his posts, or just mine?
He accused me of:

- lying 5 times
- copying a pattern/game to suit my needs
- being weak player

Which claims are more outrageous, according to you?

I can in full faith tell you: "You are a 5-time lier".
Are you happy now?

PS. and, accusing me of lying is a BIG disgrace and offence, obviously.
Hilarious - wrong medication obviously...
Still, ChessBase published an article on ME, and not on YOU.

Yes of course you are rated 3000, just like all of us here in forum with our strong chess engines running in front of us.
Where's you proof you are stronger than top engines? By showing us again your
Qf6+! brilliancy? You call it a LIVE GAME, when it was neither live nor a game.
Cannot be LIVE, because it was hand-crafted composition done OFFLINE.
Cannot be a GAME if it started from some random FEN position and
not from a start position.

That's why, just prove me wrong by posting the complete game from move 1 in a standard chess starting position, not random FEN that's composed offline.
Lyudmil Tsvetkov wrote:respect 3000
Rediculous. You are stronger than stockfish as what you claimed so you must be around 3600,
don't you think? Yes 3600, with INFINITE analysis of SF engine running in front.
Lyudmil Tsvetkov wrote:Each and every chess engine sees the first game, don't be stup*d: it is mate in 5 or 6.
Care to provide the full PV and mate announcement? Clear hash first before clicking analyze, because I know your dirty tricks of modifying something in engine output.
I checked with all top 5 engines, none can play Qf6+ of Asauskas in 10 hours.
You modified that Asauskas test position, right? Then claim you are brilliant and stronger than all engines on planet.
Lyudmil Tsvetkov wrote: so guess who discovered and popularised it.
Your ebook was published 2017, the combination of Asauskas posted in previous page was
done more than 17 years ago. You claim to discover it, lol? The truth is you discovered it from Asauskas.
Lyudmil Tsvetkov wrote: Concerning my game, I am very busy now, you have the link to the thread and are the interested party: why don't you strip the pgn yourself?
I saw the PGN there, but it started from a hand crafted FEN composition and NOT from a
starting position of a chess game with 1.e4 or 1.d4 or whatever from 20 possible first move in a starting position.
Lyudmil Tsvetkov wrote:accusing me of lying
Easy to rebut if you can post the
complete PGN game, or post the name of engines which can solve the Asauskas Qf6+!
position that you have heavily modified.

Who is playing with f7 twice backward shelter pawn?
Who is winning?

This is from 'Human versus Machine', there are 15 or so games with this pattern in the 3 volumes, so this is MY trademark.

Asauskas played a single chance game, that is it.

His position is mate in 5, my mate in 25.

25=5, right, great mathematician.

[d]r2q1r2/1b2bpkp/p3p1p1/2ppP1P1/7R/1PN1BQR1/1PP2P1P/4K3 w - - 0 1

Test position: really 64 cores don't see the mate in a reasonable time?

In my position they don't see it, that is for certain.

One way or another, this is mate in 7 or 8, with all stupid sacs counted in.
Mine is mate in 25.

If Asauskas knew something about the pattern, he would have written on it, right?
The fact is, only I wrote a book, describing the pattern.
