Jul-21-08  notyetagm: Position after 37 ♗e4xg6?


click for larger view

With his last two moves (35 ... h7-h5, 36 ... h5-h4) Geller (Black) has setup a nasty little tactical surprise for White, which 37 ♗e4xg6? did nothing to prevent.

<<<Geller has noticed that the lineup of dark-squared Black e5-bishop and White e1-queen means that the g3-square is a <TACTICAL BASE> from which the Black e5-bishop would strike at the White e1-queen. So the g3-square is a <TACTICAL BASE> and the White e1-queen a <TACTICAL TARGET>.>>>

Geller knows that he must gain control of this g3-tactical base. So first he <COORDINATES HIS FORCES> on the crucial g3-square with 35 ... h7-h5 and 36 ... h5-h4.

Secondly, Geller knows that he must <CLEAR THE TACTICAL BASE> of its defenders. Here the g3-tactical base is defended by the White h2-pawn, which is already attacked by the Black b2-rook and defended only by the White h1-king, a tacitcal situation which screams for <REMOVAL OF THE GUARD> by <ILLUSORY PROTECTION>.

So Geller (Black) <REMOVES THE GUARD> of the g3-tactical base with 37 ... ♖b2xh2+!.

Position after 37 ... ♖b2xh2+! <remove the guard>

And after the forced 38 ♔h1x♖h2 ♗e5xg3+, Geller has realized his fantasy position of a <FORK> on the g3-square involving the Black e5-bishop and White e1-queen.

Position after 38 ♔h1x♖h2 ♗e5xg3+

Note how the Black g3-bishop needs the support of the Black h4-pawn, else White would simply play ♕e1x♗g3 or ♔h2x♗g3 and not lose material. Hence the real reason for the advance of the Black h-pawn is revealed: it did not mindlessly advance to "attack" the White h1-king, it advanced to support a <BISHOP FORK> on g3!

Ingenius tactical play by Geller.

Jul-22-08  notyetagm: <ughaibu: In Geller's first appearance in the Soviet championship he finished 2nd. This game was awarded a brilliancy prize.>

What a beautiful win this is by Geller.

Jul-22-08  notyetagm: Position after 25 ... c4-c3


click for larger view

Geller (Black) has the <BISHOP PAIR (♗♗)> and a pair of advanced <CONNECTED PASSERS> for a piece, clearly a winning position.

This game is so full of beautfiful tactical shots that no wonder it won a brilliancy prize.

Nov-30-10  notyetagm: Kotov vs Geller, 1949,

Nice prelude to a winning tactical shot:

35 ... h7-h5 it's coming

36 ... h5-h4 it's coming

37 ... ♖b2xh2+! bang! it's here!

<IMPORTANT!: notice how the advance of the h-pawn supports the occupation of the <TACTICAL BASE>, just like Fischer's 14 ♕d1-b3 supports the occupation of the d5-tactical base in Fischer vs P Lapiken, 1956 >

Jan-17-11  notyetagm: Game Collection: TACTICAL TARGET DETERMINES TACTICAL BASE!
Jun-18-11  qqdos: <ughaibu> <notyetagm> The Brilliancy Prize was awarded by the Konsomolskaya Pravda newspaper, however Botvinnik one of the judging panel, rather uncharitably, pointed out that the game was not faultless and hence could not be considered as one artistic whole - <source Geller's 1962 Autobiography, translated by Bernard Cafferty (1969)>. At one point during the game, Geller had written off his own chances when to his horror he suddenly saw that Kotov had a simple move 15.f4! (Botvinnik's suggestion) "which would win a pawn and leave me with a hopeless position unless I was prepared to give up a piece." Instead an unsuspecting Kotov made the obvious move 15.Nde2? allowing Geller to pounce "in a flash" with 15...axb3! sacrificing his knight. Later, at move 22. Kotov again missed f4 "essential" which Geller felt would have given White "drawing chances"!

  LIFE Master AJ: One of the more brilliant games in the DB.

Hard to believe that its never been featured as a POTD ... or "The Game of The Day."

Jul-12-11  SimonWebbsTiger: @AJ

I agree. I wonder what Kotov thought when Geller played the star move.

Do you know the Russian for: "oh, crap" :o)

Dec-22-12  notyetagm: Game Collection: GELLER'S BEST GAMES
Dec-22-12  rilkefan: 22.e5 is equal or a bit better for white per stockfish. Black doesn't have time to take on e5 because his queenside pawns fall, and soon f4 holds it. Thus 17...b2 with a half-pawn edge was better.
Jul-06-15  saturn2: Does 37 Rg1 instead of Bxg6 hold for white? At least blacks blow Rxh2 seems not to work then. I played against Geller a simultan in 1983 or 1984 during which he won all the games.
Apr-25-18  Toribio3: Geller is truly a master of attack!
Apr-25-18  Olavi: Against 15.f4, mentioned by <qqdos> a while ago, Geller later suggested 15...axb3 also.
Jan-03-21  Gaito: The following diagram depicts perhaps a critical moment of the game:

White has an extra piece but Black has two pawns for the piece and a mass of dangerous passed pawns on the queen's wing threatening to advance at the first opportunity. This is the moment where White has to play actively, trying to bring his passive bishop into the game. Therefore, the move 22.e5! suggests itself. By sacrificing this pawn White would win a tempo to play f4, thereby freeing the square e4 for his knight and opening the long white diagonal for his bishop. For example: 22.e5! Bxe5 23.f4 Bg7 24.Bxc6 Rab8, reaching the following position:

White has activated his pieces and gained control of the squares e4 and d5. Maybe Black still has the advantage, but his task would not be so easy as in the actual game. There could follow 25.Nd5 or 25.Qe3, and White has an active position, and still holds an extra piece.

Jul-14-23  jrredfield: No luck on this one. I thought of 15 ... Nxf3 but couldn't make it work. It simply results in a lost piece for Black with no way to compensate that I could find.

I plugged the text move into an engine, but it really doesn't show it as a significant gain for Black. 15 ... axb3 16 Bxc5 Nxc4 17 Qe1 bxa2 18 Bd4 Bxd4+ and this does put pressure on White's king, but while it gives Black maybe as high as a +3 lead it doesn't mean Black should resign by any means in my opinion. A tough Friday for me.

Jul-14-23  Brenin: 15 ... axb3 16 Bxc5 (15 axb3 Nxb3 loses a P) Nxc4 17 Qc1 bxa2 18 Nxa2 Qa5 19 Qxc4 Be6 20 Qc1 Qxc5+, or 20 ... dxc5, and Black's Q-side Ps and active pieces give plenty of compensation for the sacrificed piece. But enough to win? I'm not sure, but I like Black's position.
Jul-14-23  Brenin: Maybe 17 ... b2, preserving a dangerous P, is better than losing it with 17 bxa2 Nxa2, e.g. 18 Qc2 b5 or Be6.
Jul-14-23  Mayankk: The theme of the puzzle seems to be that two connected passed pawns is worth a minor piece even if they are still in their own half. Black therefore focuses on capturing White's Queenside pawns, ignoring its hanging Knight on c5 square. It even lets go of its advanced b3 pawn by bxa2 instead of pushing it to b2 where it is temporarily protected by the c4 Knight.

A strategic masterpiece. But something I could only appreciate in hindsight.

  al wazir: Why did white play 17. Qc1 ? I think 17. Qe1 is just as good, and it requires black to find a completely different attack.

After 17.Qe1 axb2 black has clear advantage. A purpose of 17.Qc1 is that the Queen attacks black Knight on c4 after 17...bxa2 18.Nxa2.

  scormus: Didn't get much of this. With not much more than gut feeling, and because it was the only weakness I could see in W's postion, I thought it might be 15 ... cxb3. But no real plan to follow. After that I unsure about most of my picks for B's moves, except for 39 ... hxg3 ;)
