Kibitzer's Corner
Jun-06-04  Gypsy: An unheralded but superb game. Tactical motives usually reserved for some of the most exquisite mating atacks are used here to ... untangle dangerous hairball of piecess and to trasition into an accurately won endgame. The position after 27.Rg1 Nf7 is a great (hard) puzzle material. Try it!

First, Treybal's trap play (20... Nh6!? 21.h4 Qe8!?) sets up dangerous allignments on the g-file. Then, White was invited to release the tension by 24.Bxh6 Rg8 25.Bg5 Rxg5 26.Qxg5 Rg8. But game 24.f3! gives White better chances (and sets up the puzzle).

I also like the endgame play, especially the maneuver 38.Bg7+ Ke7 39.Rd1, which completely takes away all play by the Black piecess.

Sep-16-05  blingice: What about 31. Rxf7+, then take queen...
Sep-16-05  blingice: Yeah, I see no way for black to not lose at least his knight and queen for a bishop or rook.
Sep-16-05  buRnINGbeNd: 31. Rxf7+ is not possible because white is in check by the queen at h4. 31. Bxh4 is forced.
Sep-16-05  Stefan Lukke: Entertaining match.

Is "The trouble with Treybal" referring to the episode from the original Star Trek entitled "The trouble with Tribbles"? I think so myself.

Sep-16-05  Ziggurat: A move that jumped out at me when I browsed through this game was 28...Qd2+. Black's attack looks dangerous but on closer examination White seems to emerge with a slight plus given accurate play. Still it might have been a better try than the game continuation.
Sep-16-05  aragorn69: At the critical stage, the moves from BOTH players appear far from precise, but those two sure have full bags of tricks!

23.-Qf7!? (23.-Qh5 might be more resistant) 24.f3?! (24.f4! seems a lot clearer to me) Rg8 25.Kf2 Qg7 26.Rg1 Nf7 27.Be7 Qh6! 28.Qh3! (only move, that had to be foreseen when playing 24.f3) Qxh3?! (leads to a lost endgame, while 28.-Qd2+ 29.Kf1 Rxg1+ 30.Kxg1 Rg8+ 31.Kh1 f6 is a forced continuation that may be inferior for Black, but IMO is a lot more difficult to win for White), etc.

In short: tactical beauty often depends from both sides! ;-)

Sep-16-05  Gypsy: My best analysis of the <28...Qd2+ 29.Kf1 Rxg1+ 30.Kxg1> possibility goes as this:

I. 30...Rg8+ 31.Kh1 Qf4 32.Bf6+ Rg7 33.Rg1 ... (or 31...Qh6 32.Qxh6 Nxh6 33.Bf6+ Rg7 34.Rg1 ... )

II. 30...Qh6 (better) 31.Qxh6 Nxh6 32.Kf2 Re8 33.Bxd6 ... with two extra pawns and easily won endgame; Black can not save the d6 pawn for if 32...Nf7?, then 33.Rg1 and 34.Bf6+ ends the game.

Sep-16-05  kevin86: White sacs his queen in order to set up a lethal discovered check-black then gives back the queen with an odd fork of his own. The rest is anti-climax.
Sep-16-05  TheSlid: <kevin86> A "Windmill" that never was.
Sep-16-05  Norman Glaides: Black's opening play doesn't seem to make much sense - especially faffing about with the dark-squared bishop only to trade it off.

  keypusher: 29 ♕h3 is a stunner (to me). Wasn't Duras a problem composer too?
Sep-17-05  Gypsy: <Wasn't Duras a problem composer too?> A good one, too: W - Kb8 Rc2 Pb6 Pb7; B - Kd7 Ra3; White wins.
Sep-17-05  Ziggurat: <Gypsy> In your line I, black doesn't play 31...Qf4? but 31...h6 and white only seems to get a small edge.
Sep-17-05  aragorn69: <Gypsy> Same question as <Zig>: what of 31.-h6 ? (which I meant obviously in my previous post instead of f6 which is not possible)
Sep-17-05  Gypsy: <Ziggurat> You are absolutely right; I missed that. (Clever pawn moves often escape me.)

My quick, panicked-state explorations of the position after <28...Qd2+ 29.Kf1 Rxg1+ 30.Kxg1 Rg8+ 31.Kh1 h6(!)> still find White with a winning edge. First, the rooks go off the board <32.Rg1 Rxg1+ 33.Kxg1...>. If Black eschews the exchange, White would swap instead and that looks worse for Black.

Then, Black can either try perpetually harass the white king, or grab a few pawns for an endgame, or both. This leads to variations such as:

<33...Qc1+ 34.Kh2 Qd2+ 35.Qg2 Qf4+> (the endgame after 35...Qxg2 36.Kxg2 looks bleak) <36.Qg3 Qd2+ 36.Kh3 Ng5+ 37.Kh4 Qc1 38.Bxg5 ...>

or

<33...Qxc2 34.Qf3 Qd1+ 35.Kh2 Qe2+ 36.Kh3 Qf1+ 37.Kg4 Qc1 38.Kh5 Qh1+ 39.Kg6 ...>

Definitely not exhaustive, but perhaps reasonably indicative of White winning chances.

Sep-17-05  Gypsy: <aragorn69: ... what of 31.-h6 ? (which I meant obviously in my previous post instead of f6 which is not possible)> I am sure you did mean h6; I should have caught on, but I didn't.
Sep-17-05  Gypsy: Just adding a great variation: <28...Qd2+ 29.Kf1 Rxg1+ 30.Kxg1 Rg8+ 31.Kh1 h6(!) 32.Rg1 Rxg1+ 33.Kxg1 ... 33...Qc1+ 34.Kh2> and now <34...Qxc2+!? 35.Kg3 Qc1> becomes a wild and fairly promissing try for Black; eg, <36.Kh4 Qf4+ 37.Kh5 Ng5 38.Qg2 Qxf3 39.Qxf3 Nxf3 40.Kxh6 ...> But even here Black seems to come a bit short of saving the game.
Sep-17-05  Boomie: White blunts black's attack until he is no Treybal at all for the Durasion.
