Maroczy–Tartakower 1922

[AdminX]

Interesting yet speculative sacrifice from Tartakower. I was not familiar with this game. I own a copy of his classic 500 Master Games of Chess. I wonder if this game is in there. Anyway here is my output on mobile.

What if white plays Nd2xe4 ?

Then doesn't the simple Qh6 work for black? -+

Yes. After that white only has Bg2. But white can still play a game although he is more than one point down. de Qe4 Nf6 Qd3 followed by e4

I think that defense is lost because ...

17. ... Rh2
18. Nxe4 Qh6
19. Bg2 Rg2
20. Kg2 Qh3
21. Kg1 dxe4

Rg2 is worse than de.

Really! Hmm ... and here I was thinking my line was more forceful. LOL so much for my brain.

I have that classic book of Tartakower too.
I remember this game being included on that book. It was written by Tartakower and this game is a classic k-side attack of Tartakower.

Tartakower analyses the game in another classic: "Die hypermoderne Schachpartie", starting on page 404.

I found the game on page 556 (Game#429), I will go over Tartakower's analysis later in the day. I guess its time to dust off "Old English Notation"!

PS: There is a Kindle version for $5.69 USD (I might have to pick up the E-version as well)

[Kyodai]

Yes, and tartakower's comments after 17.-Rxh2

'A rare occurrence: a positional sacrifice of a Rook, based on general considerations only,
succeeds because the opposing forces are disorganised. The sacrifice fructifies nineteen moves after its consummation.'

'This break-up sacrifice succeeds only because Black is able for some time to tie up White's relief troops.'

As said Rxh2 followed by Qxf2+ is a /if not standard\ , so at least a seen
and known break through. But sometimes these familiar combinadze fail
due to some specific defensive resources.

The main question is if black wins with 17.-Rxh2 or if white can come up
with some saving resources. Of course when you comment a game won,
to some newspaper, you are sometimes prone to to be slightly biased...

[Eelco de Groot]

In this game Tartakower took on h2 with 17.-Rxh2 - can engine spot
a winning line here - or do white have some resources?

I'm very short of time so just posting the link here - scroll down and you find the game

Here's what the latest Stockfish gives in reply to Rxh2:

How do you like this line as best response from Rainbow Serpent, not Kxh2, not even Bg2 but:

I will see if the engine can reach depth 47, but maybe that takes too long on my old Q6700.

Disregarding some search instability evaluation seems to move towards zero.

FHs and FLs are manually suppressed from the output. I think I will stop because depth 47 is a bit too far.

Hi Eelco!

Here is the latest SF dev. I have, at depth 47 after some Backward of what I would call the main variant.

May I ask why you are interested in depth 47 especially?
