Zenmastur vs Ovyron No it's not another GROB!

[zullil]

My only hope is, that for the sake of the audience, Zenmastur is optimizing to stress your limited hardware resources

Me too, so far this has been my easiest game against 1.e4 of the last 12 months, black's moves can be found in 10 minutes or less (in slow hardware!) so, plagiarizing words I've read recently, I hope Zenmastur has a fairly good sized rabbit up his sleeve.

(the rabbit refers to a position with many moves with similar scores where only one of them saves the game but my hardware doesn't allow me to go beyond their event horizon so I pick one of the bad moves and lose it. Or something like that. You'd want to use a fudged eval that increases the scores of the positions that lead to such scenarios, and this could well end with scores much more accurate than what Stockfish shows)

Does that mean you have a move to play?

White's move.

White's move.

Hmmm... I posted a move yesterday I thought. Not sure what happened. No matter...

1. e4 e5 2. f4 exf4 3. Nf3 d6 4. d4 g5 5. h4 g4 6.Ng1

[d]rnbqkbnr/ppp2p1p/3p4/8/3PPppP/8/PPP3P1/RNBQKBNR b KQkq - 1 6

[Ovyron]

White's choices looking very limited.

1. e4 e5 2. f4 exf4 3. Nf3 d6 4. d4 g5 5. h4 g4 6. Ng1 Qf6

[Alayan]

Zenmastur, I got the impression from your previous messages that you have a positive eval for this position through your analysis, is that right ?

[Ovyron]

7.Nc3

I have no idea if I can predict unassisted Stockfish's moves, but can I predict Zenmastur's moves? Like, the next three? They're going to be 8.Nge2 9.Qd2 & 10.Nb5 right?

1. e4 e5 2. f4 exf4 3. Nf3 d6 4. d4 g5 5. h4 g4 6. Ng1 Qf6 7. Nc3 Ne7

That'd be unbelievable, he must be swimming in a sea of 0.00s unless he forgot to set Contempt back to 0 in his engine

1. e4 e5 2. f4 exf4 3. Nf3 d6 4. d4 g5 5. h4 g4 6. Ng1 Qf6 7. Nc3 Ne7 8.Nge2

That's why I asked, it's hard to believe the eval is 0.01 or more. And that's very significant. You can get a drawn but worse position all the way to 0.00, but it won't get positive. 2cp is negligible when it's between 0.20 and 0.22, but it can be a big deal when it's between -0.01 and 0.01 ; there is a barrier at 0.00 that is hard to cross.

Searching after Nc3 with SF-dev, multiPV=3, 4GB hash, 3th, default contempt (so favoring black here):
-1st move Ne7 at -0.46 d42
-2nd move Be6 at -0.38 d42
-3rd move c6 at -0.19 d42

Restarting with MultiPV=2 without clearing hash:
- Ne7 -0.54 d54
- Be6 -0.31 d53

The evals are less favorable to black than at low depths.

After Ne7 Nge2, the next move looks forced.

I think the KGA leads to MANY positions that Stockfish's static eval has trouble, because the bad kingside pawn structure and material deficits often have much bigger compensations than SF expects.

[Ovyron]

I don't think that'd be very significant, it'd just mean Zenmastur is missing the black's moves that go back to 0.00.
