Sep-16-06  Sularus: what a name for this opening !
Premium Chessgames Member
  technical draw: Cool game. Which proves if you Bhend something a lot it will eventually break.
Dec-25-06  Shajmaty: Better was 19...Qg5 instead of 19...Kc6?

<aw1988: If white plays Bxf6 before Na3, then black should instead play 9...f5!> Wise words.

Feb-21-07  think: Why not give back a little material with 18. ... Rxb5? It looks like black is in a little less trouble then.
Premium Chessgames Member
  al wazir: I think 16...Nb5 would have been better for black.
Feb-21-07  zugzwang: Why can't I view games here anymore the way I used to despite uploading the latest Java version as suggested here?

Any help would really be appreciated.


Feb-21-07  lentil: <zugzwang> try restarting your computer
Feb-21-07  zugzwang: Thanks for the suggestion but I have done so 3x already with the same result :-(.

I really missed the old days viewing tons of games from this site with ease.

Feb-21-07  siilarsi: <zugzwang> By uploading I assume you mean dowloading and installing...

Do you have an antivirus program? if not then install one, update it with the latest vira info, and run it (I recommend Avira:

Which browser are you using? internet explorer? Firefox? Opera? Personally i prefer Firefox ( In case you're running internet explorer, installing Firefox and upgrading it to the latest Java version might solve your problem.

Feb-21-07  Emma: Surely 11 Bxb5 isn't sound? If it is why have I never heard of it?!?
Premium Chessgames Member
  Honza Cervenka: <Emma: Surely 11 Bxb5 isn't sound? If it is why have I never heard of it?!?> It's still opening theory. This sac was a big headache for black in this line back in 1970s but later there were found solid ways of play for black against it. But it is still viable line of play for white though other possibilities are more solid. Main line of defense is 12...Ra4 and quite interesting seems to be also 12...Ra7 (see N Mitkov vs Shirov, 1994 for an interesting example).
Feb-21-07  artemis: Emma: this is a typical sicilian sacrifice. The point of this is to punish black for moving so many pawns in the opening without moving his pieces. First of all, white gets two pawns for the sacrificed piece, prevents black from castling, expedites his own castling, and forces black to move his rook, thereby gaining a tempo. Those general principles suggest to me that the sacrifice is not definitely unsound. I dont have time to provide any concrete lines, but I think if you follow <Honza>'s link, you can see some examples of stronger play by black.
Feb-21-07  Troglodyte: Isn't this sacrifice refuted? 12... Ra4!
Feb-21-07  Mole125: <ugzwang> This sometimes happens when the download of the viewer got currupted in transit. Get your browser to delete its cache (in ie internet options|general|temporary internet files|delete files, in other browsers its often under delete private data or similar). This will mean that the browser will download the applet again and the new version will hopefully be valid
Feb-21-07  twin phoenix: wow someone played ol pelican against me yesterday in speed chess. this looks like a great weapon for speed! can't wait for someone to try pelican again!!! (funny bird is the pelican, it's mouth holds more than it's belly can!)
Feb-21-07  twin phoenix: after looking at Honzas link i'm even more convinced this sack is sound. black in that game immediately returns the material (giving R+2P's for N+B). white was clearly winning in the ending and i have no idea how he lost. (except for time pressure...) anyone know of a more convincing 'refutation' of the sack?
Feb-21-07  tacite: Looking at the black king trying to hide, the pun could have been : Bhend on the run.
Premium Chessgames Member
  kevin86: White gives up bishop for two pawns and an entrance by the two knights! With the horses on the rampage,the black game goes downhill fast.
Premium Chessgames Member
  fm avari viraf: This is a beautiful game well executed by Nunn. I had the opportinity to play this line but my opponent played 12...Ra4 which is the main line. If Black defends well , I think he can survive in the end. But God made middle game before the end game!
Feb-21-07  blair45: At least no one's making puns about nun(n)s!
Feb-21-07  zugzwang: Thanks for your suggestions guys. Will try your suggestions and hopefully it works.


Feb-10-09  Katu: What if 12. ...Qa5+ ?
Premium Chessgames Member
  Phony Benoni: <katu> 12...Qa5 has been tried a few times. If you're interested, here are a few games to look at: B Vukcevic vs N Povah, 1984, J Isaev vs R Barakat, 2002, D Mastrovasilis vs R Espinosa-Flores, 2004, P Morales vs F Corrales Jimenez, 2007.

Of course, you realize that Black cannot play play ...Qxb5 due to the K+Q fork on c7.

Feb-12-09  Katu: Thanks for the effort. But my name starts with "K".

(not "k"...)
