More Stonewall RAM

The Maroczy-Tartakower game was excluded from our Stonewall book mainly because it didn't really match our recommended repertoire. Today's game might have made it had it been in the databases (or had my memory been a bit more consistent). I only remembered it when annotating Tartakower's brilliancy. The reason it is missing in BigBase/MegaBase may be that the game information is unreliable. Different sources offer different years and different spellings for White's name. As for tournament/event I have no idea.

Glinksberg - Najdorf
Warsaw 1928

1.d4 f5 2.c4 Nf6 3.Nc3 e6 4.Nf3 d5?!
4...Bb4 is fine for Black.

As mentioned elsewhere 5.Bf4 is very good for White.

Black can more safely reach this position from the move-order 4.e3 d5 5.Nf3 c6.

6.Bd3 Bd6 7.0–0 0–0 (Dia)
This position is fairly attractive for Black who has won a number of short games.

This move has been criticized but probably wrongly so as Beliavsky has played it recently. Our book only mentions 8.b3 and 8.Qc2. Another option is 8.Ne5, planning the stodgy counter-Stonewall with 9.f4.

A more recent game went 8...Ne4 9.Ne1 b6 10.f3 Nf6 11.cxd5 cxd5 12.Bd2 Qd7 13.Rc1 Ba6 14.Qb3 Rc8 15.Rxc8+ Qxc8 16.Bb4 Bc4 17.Qa3 Bxb4 18.Qxb4 Nc6 and Black was fine in Beliavsky-Vydeslaver, Kallithea 2008. It is symptomatic that Beliavsky couldn't win against his presumably weaker opponent.

9.Ng5? Bxh2+!
This isn't quite as simple as it seems. Black must have calculated quite far or trusted that the neccessary resources would present themselves as play developed.

The obvious point was 10.Kxh2? Ng4+ and Black wins an important pawn. Now he threatens to trap the bishop with g3 as well as Nxe6.

10...Ng4 11.f4 Qe8 12.g3 Qh5 13.Kg2 (Dia)
White is now ready to pick up the bishop with moves like Nf3 and Rh1.
13...Bg1! 14.Nxg1
Any other capture loses immediately.
14...Qh2+ 15.Kf3 e5!
This is the key to Black's combination. The threat is ...e4 so White has no choice.

16.dxe5 Ndxe5+!
Remarkably Black succeeds in sacrificing all his minor pieces in this game which has been called 'The Polish Evergreen' (or Immortal or something like it).
17.fxe5 Nxe5+ 18.Kf4 Ng6+ 19.Kf3 (Dia)

In early calculations it may have been reassuring for Black to have a draw as a back-up. But does he actually have anything more than a repetition?
This obviously lets the light-squared bishop into the game. What's less obvious is that the rook too joins the attack.
20.exf4 Bg4+! 21.Kxg4 Ne5+! 22.fxe5 h5# 1–0

Lesson to be Learned:
Never underestimate Black's light-squared bishop in the Stonewall.
