Jul-31-15  akiba82: Not a good outing for Williams.

He beat Howell last year, and has beaten world championship challenger Gelfand, so is not outclassed against Howell. Nonetheless he seemed too anxious to make something happen here. He sacs a rook and three pawns for two pieces, but doesn't really have the development to make the sacrifice work.

Jul-31-15  akiba82: Williams needs to work on his technique so he wont be so dependent on his considerable attacking skill when he goes up against the big guns.

Perhaps he also needs to work on physical fitness and spend less time in the pub!

That being said, I'm still expecting him to go on a tear and get back into contention in this tournament.

  tamar: "Hair of the dog" attack.
Aug-11-15  akiba82: Williams has provided commentary on this game at his website. He makes a convincing argument that his double pawn sac left him with decent compensation. His mistake came later with 13 Re4 ?! instead of simply 13 Nc3. And even after the dubious exchange sacrifice he maintains he could have given himself better chances if not for 18 Bf5?
Aug-11-15  akiba82: There may be a lot better practical chances for White after moves like 18 Nc3 or 18 Ng5 than I realized. One of the hazards of patzers attempting to critique gms I guess. Any way, check out his commentary to get a better handle on this game. His chess may be erratic at times but Williams is an excellent chess instructor.

  Penguincw: Ugh, Sunday puzzle. White threatens multiple mate in 2's, how to stop it.

I got 20...Bxg5 21.Bxg5, but did not see 21...f6. Great move, as it allows the queen to defend horizontally.

I also predicted ...Re1+ Kg2 would be played.

I remember coming across this game, although did not comment on it.

< PhilFeeley: Must have been serious time trouble. It's fun to watch Williams sac everything, but Howell calmly refuted it all. >

Agreed. It seems like white just ran out of firepower in the end.

Jul-10-16  jd4chess: don't really get the point of this one, thought the first two moves were fairly easy to find, and then it's a matter of trying to hold on against whatever white tries.
Jul-10-16  YouRang: Much to my surprise, I didn't do too badly on this "insane" puzzle 20...?

Materially, black seems a bit better, up a R+3P for a B+N. Furthermore, white has neglectied his queenside development, leaving his Bc1 ripe to be picked off by a ...Re1+ fork.

However, white has an attack underway, threatening Qxh7+ ...Kf8 Qxf7#

So the first move is fairly obvious: <20...Bxg5>, which eliminates the attacking N and sets up the ...Re1+, forking K and Bc1.

White has a choice: Recapture with B or Q?

~~~~

<21.Bxg5> -- I should think taking with the DSB is more attractive for white since this avoids the ...Re1+ fork, and white now threatens Bf6 with mate to follow.

The best way to answer that is to clear the 7th rank with <21...f6>


click for larger view

This allows the Q to defend the king, and turns the tables since black is now attacking both bishops.

White can try <22.Bxf6> and now 22...gxf5 leads to draw by repetition (23.Qg5+ Kf8 24.Qh6+ Kh8). However, <22...Qf7!> pins the two bishops. If <23.Qg5> to guard them, then <23...Rf8> and a bishop must fall.

~~~~

<21.Qxg5> -- White instead takes with the queen, but <21...f6> still seems to work: <22.Qxf6 Qf7>.

Again, black is threatening both bishops (the LSB with Pg6+Q, and the DSB with ...Re1+). White can't save them both.

Not so insane after all...

Jul-10-16  AlicesKnight: <Penguincw> "It seems like white just ran out of firepower in the end". Perhaps also Tal vs Keres, 1959 is an example from a "great".

You do not consider that either of these players was great, with the former winning the world championship the year after the game in question, while the latter had merely one of the finest careers by a player who never won the title?

  Richard Taylor: The trouble is from the position I thought there might be some brilliant counter attack by Black involving taking on g5, playing f6, I saw those two as being necessary but then Re1+ followed by c5 trying to mate the king on g2 but white brings his N to d2 and it doesn't work....

So the best line was what was played but not what White played. But Black simply defends by going to f7 with the Q. In other words the more or less obvious moves were in order in this position.

So, prevent mate, then pick up material and win as Black. Black was under some pressure though.

  agb2002: Black has a rook and three pawns for a bishop and a knight.

White threatens 21.Qxh7+ Kf8 22.Qh8# or 22.Qxf7#.

The obvious move is 20... Bxg5 21.Bxg5 (21.Qxg5 Re1+ and 22... Qe7 - +) 21... f6 (21... gxf5 22.Bf6 + -; 21... Nd7 22.Bxd7 Qxd7 23.Bf6 + -) 22.Bxf6 Qf7 (22... Re1+ 23.Kh2 Qf7 24.Nc3 Rxa1 25.Be6 + -) and White's attack seems to vanish while Black keeps some material advantage and gets the better prospects.

The alternative 20... Bf6 looks losing after 21.Qxh7+ Kf8 22.Bxg6 (22... Re1+ 23.Kh2 Rxc1 24.Ne6+ Ke8 (24... fxe6 25.Qxb7 + -; 24... Ke7 25.Qxf7+ Kd6 26..Qxb7 + -) 25.Qg8+ Kd7 26.Qxf7+ Kc8 27.Qe8#).

That's all I can do today.

  Richard Taylor: Kudos to Williams for an enterprising attack.
Jul-10-16  wooden nickel: Being an "insane", first tried 20... Bf6 in vain! The only difficulties upon the logical 20... Bxg5 are avoiding perpetual checks. For example 20... Bxg5 21.Bxg5 f6 22.Bxf6 gxf5 23.Qg5+ Kf8 24.Qh6+ Kg8 25.Qg5+

Jul-10-16  AlicesKnight: <perfidious> Sorry if my comment misled - the "perhaps" refers to the nature of the game ('running out of firepower'), not the players (both great); I'm open to better examples of such games.

  morfishine: <Richard Taylor: Kudos to Williams for an enterprising attack> Gutsy, but hardly enterprising from a capitalistic point of view: No profit

Jul-10-16  NBZ: Looking at this as an "insane" puzzle skewed my judgement! Bxg5 Bxg5 is pretty much forced (if Qxg5 Re1+ and Rxc1 should win for black). Then ..f6 Bxg6 is I think the critical line: I only saw fxg5 Bxe8 and white is a piece up, forgetting the simple Re1+ as played in the game. Of course, if you actually reach the point in the game where White plays Bxg6, it's rather obvious what Black should play...

Like Richard Taylor I also felt the need to launch a brilliant counter-attack. Here's what I came up with as a "drawing" line for Black, it's actually pretty interesting: Bxg5 Bxg5 Re1+ Kh2 Qa6 Bf6? (in retrospect simply Nd2! Rxa1 Bf6 wins) Rh1+! Kxh1 Qf1+ and draw by repetition.

Jul-10-16  drollere: sunday puzzle? hmm.

20. ... Bxg5 is forced, 21. Bxg5 is natural.

the threat is 22. Bf6 and mate. i thought 21. ... Nd7 with 22. ... f6 was worth looking at, though clearing the 7th rank for the queen was safer given the material advantage.

22. ... Re1 was a snappy interpolation, and "22. ... black to move" seems a more interesting puzzle.

  morfishine: <Pedro Fernandez: Chess Games should not put this kind of so poor games as a puzzle, honestly> Hi Pedro! This is true, but I think we have to give <CG> benefit of the doubt: Every day they humbly produce a position for us poor yet eager chess players. The last thing we would do is complain

Jul-10-16  Patriot: The first few moves are really easy. White has a killer move which leads to mate (21.Qxh7+). I only saw one way to stop the mate, 20...Bxg5. After looking a little more, 20...Bf6 is another way to prevent immediate mate and at least allows the black queen to guard f7.

So after 20...Bxg5 21.Bxg5 now white has another killer move (22.Bf6). So, 21...f6 attacks Bg5 and also threatens to take on f5. It also allows black to guard g7 with the queen.

Yes I looked at the Qa6 Idea as well as c5 I didn't see Nd2 which is one of those "obvious" moves so hard to see if you are trying a quick attack.

  Richard Taylor: I played in the same tournament as Howell once. He is a quietly spoken and quite nice fellow. He of course stayed in the top boards while after one game near the top I fell to grovel among the sodomites!
Jul-11-16  Stalwart: I agree with Pedro (VOTE PEDRO!)
