Kibitzer's Corner
Mar-29-10  think: Each positive integer can be broken down into prime factors. You could say that a chess game could be broken down into factors as well. One such factor of this game is the advantage of good king position in the endgame.
Mar-29-10  Jettrider: 34...Bxe5

Black's temporary sac did nothing but simplify the position. It also allowed 38. Bd4, a nice forced simplification.

Game is completely lost after 41...Rd5. White has ample ways to promote the e-pawn.

  FSR: The prime factors of 1936, when this game was played, are 2, 2, 2, 2, 11, and 11. (1936 is 44 squared.)
Mar-29-10  Bobwhoosta: <JettRider>

I have the distinct feeling that black's game is approaching lost after 22. a5. White seems to have a huge advantage. Black defends very well afterward, but never fully equalizes.

Not sure where the final mistake is though...

  FSR: 8...e5 seems like a really horrible idea; not surprisingly, this is the only game in the database where it was played.
Mar-29-10  Bobwhoosta: <bobwhoosta>

Don't you see the total gamelosingness of g5 you cad!?!?

<Whoosta to Whoosta>

Ah, I supposed you're right, after some forcing lines black is led straight into the 34... Bxe5 simplification <JettRider> talked about...

Any better moves out there??

<Bob Responds>

Maybe we should go move in with the nice men in the white coats again???

But seriously, most moves are better than g5.

Mar-29-10  Garech: I don't think this game is of a good enough standard to be GOTD. Is there something behind it that I'm missing?

  OhioChessFan: Black should have been lost after 12..Nd3. He apparently liked how his outposted Knight looked, but missed how simple it was to remove the defender. Oddly enough, so did White, since he missed 13. Nd5

  OhioChessFan: I think Black missed an easy perpetual with 28....Ra3+
Mar-29-10  charlietheman: g4 essential touch
Mar-29-10  sfm: <Think: Each positive integer can be broken down into prime factors>

1) The number 1 can not.
2) "prime factors" is pluralis, however, prime numbers can only be broken down to one single factor.

So in other words, the statement is totally wrong and I... What? "...hysterically pedantic and off topic"? Me??

Mar-29-10  TheTamale: But is it the greatest prime Factor?
Mar-29-10  kevin86: Breakaway! The pawn goes in for a score!
Mar-29-10  tivrfoa: nice endgame
Mar-29-10  Bobwhoosta: <Garech>

Collosal clashes of the kind witnessed during the Kasparov Karpov WC match do not happen every year.

Tournaments of the caliber of Linares do not happen every month.

Games of the level of Ivanchuck through all of Amber do not happen every week.

Super GM tournaments do not occur every day.

There are 365 days in a year, and the pool of amazing chess games grows at a rate that is overall much slower than this.

What are your requirements for GOTD that will also allow for a GOTD to actually exist??

  xenophon: all Harry hill fans will recognise the K factor in this-apologies to the >95% who will have no idea what I'm talking about
Mar-29-10  operative: Nice maneuvering there at the end. I stink at endgames! :((
Mar-29-10  Bobwhoosta: Here are my thoughts (Understand I am making them up as I type...)

1. A GOTD should teach us something about chess.

2. A GOTD should contain either a demonstration of orginal thinking, or good technique.

3. I would like a GOTD to contain an overall theme as often as possible, although PURELY thematic games are difficult to find.

4. GOTD could be a game containing something irregular, even if it is just a single tactical shot, or an obviously bad move that makes us go "Oh, so even HE can do that...", and thereby encourage us in our failed games. (Kramnik's Deep Six (missed mate in one) comes to mind).

5. GOTD should be fun.

I think this game is a GOTD.

  FSR: <OhioChessFan> If 28...Ra3+, White can avoid the perpetual with 29.Kf2 Ra2+ 30.Kg1 Ra1+ 31.Kh2.
Mar-29-10  WhiteRook48: if it lasted for one more move, then it would be prime...

30...Be1 Now what?

  FSR: <OhioChessFan> That is certainly awkward for White to deal with - maybe 31.g4 Bg3 32.Be3 Ra1+ 33.Bf1 intending to untangle with 34.Kg2?
Mar-31-10  Garech: <Bobwhoosta>

<Collosal clashes of the kind witnessed during the Kasparov Karpov WC match do not happen every year> etc

There are over half a million games in the database! Even if it is a game between club players, it can still have some great ideas/positional play - or even some cheap but pretty tactics. Something amusing, also, like the recent one from the Swedish U18 tournament with each side's knights switching places before the game proper starting, would be good too. But this game seemed very run of the mill; nothing spectacular, funny - not even some story behind it or anything. I realise the GOTD is voted in so perhaps that is where the problem lies. Either people are voting for a lower standard of game, or not enough worthy games are being submitted. I have volunteered about a dozen good ones myself. In any case, I still hold that this game wasn't of a high enough stanrard - I don't think I'm alone in my opinions either. It's bad for several reasons - firstly, it's a disappointment to everyone who comes to the site daily, including me, looking forward to seeing an entertaining game, and also - it makes chessgames.com itself look a bit ridiculous because it's making out that the webmasters/members think this game is good when in fact, for the most part, nobody does! So - I think we should put the message out there for people voting in the Pun Booth to raise their standards, and for people submitting games to really make sure they are good, for everyone's sake!

<31...Bd2>

32. f5 c5 is amazingly strong for such an innocuous Pawn push.

33. Bxc5 Bb5 and the Rook is toast.

33. Rxc5 Be3+ 34. Kh2 Bf4+ etc etc

or 32. e6 Bxe6 33. Rxc6 Bxf4
