  Fusilli: <perfidious> A W-9. I think you report it under miscellaneous income.

  perfidious: <Fusilli> Never heard of a W-9; in my profession/avocation, the W-2G is the form.
Aug-12-14  BOSTER: <Fusilli: I am mostly proud of 22...f5!>

Playing white I'd prefer to have the such pos.
As a gift I'd give black the rook
on e1 in return to put the queen on e1.

Improvisation.

white to play.

  Once: <BOSTER> Yes, yes, Ng6+ followed by Qh5#

Except the white queen isn't on e1.

We would all be world champion if we could put our pieces on whatever square suited us.

And here I've been thinking all day that it's Tuesday ;)

Aug-12-14  ajile: So I'm guessing Black got a few ratings points for this game.

:o)

Aug-12-14  BOSTER: What if
in the pos. white to play 26. he played audacious Re4 taking control under f4, no retreat for knight on g5.

  OhioChessFan: White's errors led him pasta point of no return.
Feb-21-15  YouRang: After 17 moves, the position was as follows:


click for larger view

White, evidently and understandably annoyed by the black's LSB pinning his Nf3, decided to kick the LSB with <18.g4>.

Advancing this g-pawn however, weakens the white king's defenses and makes the Pg4 a good target. We see black going to work on that idea over the next few moves:

After <18...Bf7 19.Ne4 Bd6 20.Qc1 Qd7 21.Nh4 Be6 22.f3>


click for larger view

As you can see, much of black's firepower is now aimed at black's kingside, and such buildups often lead to attacks in which the attacker can afford to sacrifice material to destroy the defenses.

It is at this point where black begins his attack with <22...f5!>, which not only attacks the Pg4, but opens lines of attack for black.

White replied with <23.Ng5>, which wasn't best (22.Nc5 attacking the Q+LSB while being protected by a pawn is better).

Black did find the best continuation with <23...Bg8!>, preserving the LSB such that it guards e6 and f7. Black now threatens Bg3, forking the Re1 and Nh4. White alleviates that threat and takes out the pesky f-pawn with <24.Nxd5>.


click for larger view

But black seizes the opportunity to dismantle white's vulnerable kingside with the exchange sac <24...Rxf5! 25.gxf5 26.Qxf5>


click for larger view

Things are pretty drafty for the white king. His best defender is the extended Ng5 which can easily be kicked. Black threatens ...h6 or (even better) ...Nf4.

White playes <26.Qb1> hoping to diffuse black's attack by exchanging queens, but <26...Qf6> maintains the threats. White follows with <27.Qe4> guarding Pf3 but leaving Pb2 unguarded.

<27...Rxb2!> adds another strong attacker on the 2nd rank. White attacks the R with <28.Bc1>.

Black ignores the rook threat because <28...Nf4!> brings another attacker to the kingside and threatens Qxg5+. If 29.Bxb2? then 29...Qxg5+ 30.Kf2 Qg2+ begins a fun (and successful) king hunt for black.

White guards the Nh5 with <29.h4>


click for larger view

But black's attack is strong enough that removing the best defender is worth more than the queen. The game ends with a pretty flourish: <29...Qxg5!>.

If 30.hxg5, then 30...Nh3+ gives white the sorrowful choice of 31.Kf2 Rf2# or 31.Kh2 Rh2#.

Feb-21-15  optimal play: <YouRang> <White, evidently and understandably annoyed by the black's LSB pinning his Nf3, decided to kick the LSB with <18.g4>. Advancing this g-pawn however, weakens the white king's defenses and makes the Pg4 a good target.>

I'm always wary of kicking away a bothersome bishop-pin by pushing my knight's pawn to the fourth rank for exactly that reason!

I notice <Fusilli> himself did just that only recently T D Andrews vs M Sana, 2015 and paid the penalty!

But in this earlier game he takes advantage of his opponents vulnerable kingside with some inspired play!

Great win against an FIDE Master in the US Open!

Feb-23-15  YouRang: <optimal play> You're right, that other game with T D Andrews does bear some resemblance to this game -- except with the tables turned.

That is, in that game black advanced the g-pawn and white attacked it with the f-pawn. However, it was different in other respects. White didn't prepare a nice offensive buildup prior to the f-push, and black may have been okay except for mistakes later on.

Feb-23-15  optimal play: <YouRang> I concur with your distinction between how those two games were played, and in that regard, I wasn't really comparing the two games themselves, which as you correctly pointed out, are quite different.

I just couldn't help but notice how in each of them, the advance of the g-pawn weakened the k-side, resulting in defeat, and it reminded me of some of my own games in which either myself or my opponent played g4 after h3 (or conversely g5 after h6) to kick away a bishop-pin, only to eventually see the king become dangerously exposed.

I'm sure this doesnít always lead to a loss, but I've personally found that move often creates a somewhat precarious position on your k-side, which is why I'm always wary about playing it.

Maybe sometimes it's just better to put up with the annoying pin?

Feb-24-15  YouRang: <optimal play> I'm pretty sure that playing g4 after O-O (or ...g5 after ...O-O) is one of those moves that sometimes it works and sometimes doesn't -- and you just have to know the difference.

Knowing the difference is of course the trick. I suppose the primary consideration is whether or not your opponent will have the time and forces to take advantage of the weakness. If not, then advancing the g-pawn may gain space with tempo, carrying with it some advantages for later in the game.

For example, in our 2nd World game with GM Akobian, we (white) played 11.g4 (to kick a N; not a B), but black's position was cramped such that he was unable to exploit this weakening of our king position.

The World vs Akobian, 2012

In fact, the resulting space and open file was ultimately used by white to affect a nice winning attack on black's king.

Feb-24-15  optimal play: <YouRang> I agree with all your comments, but I would posit that advancing the g-pawn in isolation, such as in The World vs Akobian, 2012 or say, the Keres attack in the Sicilian, Scheveningen (B81), are quite different from playing g4 *after* h3 when castling short.

The h-pawn especially becomes a weak point, and if capturing on the g-file, can leave the king dangerously exposed.

Of course each game is different, and sometimes it may be the best move to make, depending upon the position, but I've seen enough losses to warn me about pushing g4 after h3 without very carefully considering my ability to defend against a k-side attack.

Feb-24-15  YouRang: <optimal play> All agreed. The sequence in Akobian was certainly different. We played h3 later, but of course the motivation was all different.

I was looking for a counter-example (not that it was needed) and was too lazy to look for a proper one.

But I happened to remember that the Akobian game featured this g4 push. I vaguely recall that some team members were leery of it for its kingside weakening potential, but it was a case where I think the virtues outweighed the faults.

Feb-24-15  optimal play: <YouRang> <... I happened to remember that the Akobian game featured this g4 push. I vaguely recall that some team members were leery of it for its kingside weakening potential, but it was a case where I think the virtues outweighed the faults.> Yep, although I can't remember if I was one of those <leery> members, I notice that in the end I voted for it!

<Sep-21-12 optimal play: Itís a choice between 11.g4 or 11.b4 Is GMVA going to castle short or long? Is he going to castle at all? 11.g4 Nh4 12.Nxh4 Bxh4 13.f4 looks pretty good whatever he decides.>

But anyway, if the particular position indicates that h3 followed by g4 is indeed an instance where the virtues outweigh the faults, then of course it can be played with a level of confidence.

Bear in mind however, that level of confidence is always higher if you can run it through a computer! ;)

  Fusilli: <Optimal Play>, <YouRang> I think there are some examples out there of black playing h6 and g5 after 0-0, kicking the white bishop to g3, and gaining a strong square on f4 for a knight. I vaguely remember seeing a few classic games, maybe with Steinitz handling the black pieces, probably in Reti's "Masters of the Chess Board". But it's been too long ago, and I don't have the book. I looked in this database for games won by Steinitz handling black against the Giuoco Piano and couldn't find anything...

  Fusilli: Here's a fun game where h6 and g5 (with 0-0) succeeded:

R Kuijf vs Campora, 1984

Here's one where it backfired:

Staunton vs Popert, 1841

Feb-25-15  optimal play: <Fusilli> R Kuijf vs Campora, 1984 is indeed a fun game, except that white should have won after 34.Rg3!

And interesting how Staunton capitalised on Popert's exposed k-side, not by capturing the g & h pawns, but in by-passing them with his f-pawn!

Also notice how Popert's king has to defend the h-pawn without the g-pawn at home? That's another reason why I'm wary of pushing up that pawn.

Feb-26-15  Rookiepawn: A la pelota! Sacrificate algo...

It looked clear to me that after 22. f5 the exchange sac would be the natural way to follow, but couldn't be sure about the whole plan. It always looks easy afterwards ;). The Q sac, though more straightforward, is the cherry on the top. Beautiful attack.

Feb-27-15  YouRang: <optimal play: <Fusilli> R Kuijf vs Campora, 1984 is indeed a fun game, except that white should have won after 34.Rg3!>

R Kuijf vs Campora, 1984

Yes, but I think white had winning chances there mainly because black's <19...Nxg2?!> knight sac, while fun, was unsound.

It looks like black would have had a legit strong game with 19...e4 with ...d5 coming up.

Hence, that game may serve as a good example of the case where advancing the g-pawn was really a decent option (for black in this case).

Feb-27-15  optimal play: <YouRang> Yep, that's a valid point!

Advancing the g-pawn may be a decent option, but perhaps it leaves you with less margin for error?

The potential risk of an exposed k-side may be outweighed by the advantages which come from that strategy, provided you don't embark on any unsound sacrifices? ;)

  Fusilli: <Serbon91: <Fusilli> Superb combo in the end!Bravo!>

Thank you! :)

I noticed that in the Chess Base megabase the last recorded move is 29.h4. What happened was that my opponent was taken by surprise by Qxg5+. He resigned on the spot and I guess never wrote my last move down on his score, then dropped the score in the box, and those who entered the moves on the computer used his score, not mine. So, in the most used database in the world (and every other database that feeds from it, see for example http://chess-db.com/public/game.jsp...), my 29...Qxg5+ went unrecorded, as if he had resigned before I actually made that nice move. I resent that... but there's nothing I can do. Oh well...
