Chess960 puzzle no.18

One of the most amazing queen entrapment tactical scenarios I've seen in Chess960 yet. Enjoy the puzzle.

SP598 White to play: Can white catch the queen
and get back to material equality?

Solution below



Solution: NO! Black's queen cannot be captured without significant losses. Best is to sacrifice the exchange to keep black's queen out of play.

Wrong solution:
6.Be3...cxd4 7.cxd4...Ng6! 8.f3...Bb4+ 9.Ke2...Nf4+ 
now follows the amazing line:
10.Bxf4 b6 11. Ndf2 Ba6+ 12. Ke3 Bxf1 13. Rd1 Nc6 14. Ng3 Bxg2 15. Rxg1 Bxh3

Correct solution:
6.Ng3...e5!! 7.Ne2...d6! 8.Qh5...Bg4!! 9.Qxg4...Qh2 
white is down an exchange but black's queen is out of play

Chess960: Transcript of Showdown in Saint Louis 2015 - SP112 Negi v Yifan

Here is a transcript of the first fischer random game between Hou Yifan and Parimarjan Negi at the Showdown in Saint Louis competition 2015.

Rumours have it that the organizers experienced technical difficulties during the event, so there are no PGN records for the games available in the public domain. I have had to reconstruct the games from the video recordings on Youtube and Chess24. In order to save time and effort, I have transcribed only the opening phases of each of the games since that is what interests us in Chess960 - the rest is just chess!

To save space in the comment text, the three commentators are initialed as Yasser Seirawan (YS), Jennifer Shahade (JS) and Maurice Ashley (MA).

Chess960: The more the better? part 3

This is a continuation of the discussion of Basque Chess960 that was had *here* and *here*. In Basque Chess960 each player simultaneously plays one board as white and the other as black. I've played it a few times and think that it is a wonderful way to play Chess960 and really makes sense because it eliminates any differences in advantage that the white player has.

I found that it is even possible to play Blitz Basque Chess960 because two games are not that difficult to keep a track of - our brains seem to be pretty good at seeing in double! If anything, I found that Basque Chess960 actually maintained or improved the quality of my blitz play because I could not stop to think - it forced me to play instinctively. Stopping to think in Blitz can often make your play worse not better.

With that in mind, I was surprised that the two commentators at the Showdown in Saint Louis 2015 exhibition match between Hikaru Nakamura and Fabiano Caruana were intrigued by the Basque Chess960 idea too. Here is a transcript of their thoughts as they were commenting game one of the Chess960 competition:

Jennifer Shahade: "I really wish that we had Basque Chess for Fischer Random don't you? So that we could see how Fabi would tackle playing white (in contrast to Hikaru)"

Yasser Seirawan: "Oh that would be intriguing for sure"

Jennifer Shahade: "I think in Fischer Random it really makes a lot of sense, because you get to show....cause it's to easy to say after the game 'hey white just has an edge in this particular Fischer random'. But if you play Basque Chess960 you have to show it from both sides"

Basque Chess960 is a lot of fun, equalises fairness 100% and you get twice the game for each start position. You can also play it against the computer if you set up two Winboards side by side on your screen.

Enjoy 960

Chess960: Showdown in St. Louis - Fischer Random Style

I'm in the middle of transcribing the Chess960 portion of the video recording of Hikaru Nakamura playing Fabiano Caruana in Chess960 (Fischer Random) at the recently concluded Showdown in St. Louis 2015.

Here is an interesting idea that the commentators mentioned during game one of the Fischer Random portion of the event, as to why Chess960 has been slow on the uptake.

Jennifer Shahade:  "Obviously Fischer random is just perfect for somebody like Nakamura he really loves the game. I really like it too. Why do you think it hasn't begun to be even more popular Yasser?"

Yasser Seirawan: "You know one of the things, I've spoken to a lot of my colleagues on this very question. One of the things is a lot of my colleagues feel it has to do with amateur players. That is to say amateur players are so vested in their openings, they want to see players playing the French defenses and their Sicilian dragons and they know those openings so very well, they want the players to play their favourite openings and favourite defenses. Instead, when the players are playing a game of Fischer random, then a lot of the amateur players say "gee I don't know this position, I don't know what's going on". A lot of the professional players like Fischer Random and would like to see more Fischer random events. Its sort of like the organizers are hearing from the amateurs "no don't do it we want them to play OUR openings, OUR defenses". Its kind of an intriguing idea right?"

Jennifer Shahade: "It is strange because normally you hear amatuers complaining about how much opening analysis there is but when push comes to shove they like it in a sick way."

Yasser Seirawan: {laughs}

If that is the case that amateurs are actually the ones holding up the progress of Chess960, we just have to wait for critical mass to occur when finally the amateurs make the switch to 960. According to the Chess960 popularity counter *here*, we have probably got another 20-30 years to go until the tipping point occurs. Popularity is steadily rising, but there is still a long way to go.

In the mean time, remember that Chess960 is not here to replace Chess, just be a viable loved alternative to chess and be its equal.

Enjoy 960.

Chess960: When the queen comes out early

Found a brilliant example of a start position where the queen can come out with attack as soon as the second move. The amazing thing is that there is no way to attack her and she is immediately putting pressure on the opponents position:

SP169: Queen out on move 2!

White starts with the Birds Opening System 1.f4 except here this opens a line for the queen to come straight out into the middle of the board. White follows up with the strong move 3.c4!? which achieves multiple things:
  • Immediately attacks d5
  • The d5 pawn is pinned against the undefended d8 bishop
  • If black tries to attack the queen to gain tempo with something like c6/Bb6, white plays c5!? blunting the attack and preventing the corner knight from being able to develop.
  • White has not really neglected king safety because of O-O/Bf2 combination.
I haven't seen such a clear example like this before for bringing out the queen early with no cheap way of counter attacking her. Black has plenty of options, but it is an amazing little start position #169 that's for sure! It all stems from the pin on the d5 pawn against black's dark bishop.

Chess960 puzzle no.17

Should white be freaked out by white's attack here? I found myself ruminating over this question during a game. I realise that this does not even look like a Chess960 problem any more but when you think about it, how else could black's knight have reached d6 without it being Chess960? The point is that Chess960 does throw up different versions of classic chess mid-game themes.

It turns out to be a nice puzzle because it can be broken down into individual problems that can  be independently analysed to arrive at a solution. The threat is black can aim all his big pieces down the f-h files in tandem with opening up the kings's safety - a standard hack attack.


SP076 Black to play - does black have a serious attack on white's king?

Answer bottom left hand corner of this page







Solution:
Break the problem down into manageable chunks.
A) If ...f5 white plays e4 with a strong attack
B) if ...g5 white has the defense Bh4! followed by g3
C) if ...h5-h6 white has g3 stopping black's progress

A+B+C means white can safely proceed with a queen-side (c-side) attack
Answer: no!
