|Sep-14-07|| ||OBIT: Hmm... either both players missed QxQ, or the actual moves played were 11... Bxf3 12. gxf3 Qe1+ 13. Kf4 Draw agreed|
|Oct-16-12|| ||FSR: Undoubtedly Black played 11...Bxf3 12.gxf3 Qe1+, a well-known drawing line, http://www.chessgames.com/perl/ches..., rather than hanging his queen.|
|Oct-16-12|| ||perfidious: <OBIT> et <FSR>: The correct continuation was indeed played according to another source; I'll submit a slip to that effect.|
Maybe the Kosintsevas will have a go at this when they get bored with their hundredth encounter in the Spanish Exchange. There's always hope, anyway.
|Oct-16-12|| ||Olavi: Actually the Kosintsevas could do a great favour to chessplayers all over the world. There are hundreds of correct, delightful, yet quite unknown short forced perpetuals or repetitions; why don't they educate people!|
|Oct-16-12|| ||perfidious: In ten known encounters (nine draws), the longest game between these players was thirty moves (twice), with Razuvaev actually winning their last, in one move less.|

|Oct-16-12|| ||Olavi: <FSR> A beautiful collection, wth many gems undoubtedly fought to the bitter/satisfactory end. Yilmaz-Kouatly from the 1984 Olympiad seems to be mising fron the database: 1.e4 c5 2.Nf3 Nc6 3.b4 cxb4 4.d4 e6 5.d5 Qf6 6.c3 bxc3 7.dxc6 c2 8.Qxc2 Qxa1 9.e5 Ne7 10.a3 Nc6 11.Bb2 Nxb4 12.Qc1 Na2 draw. If 13.Qc2 Nb4.|
|Oct-16-12|| ||Olavi: Sorry for the typos.|
|Oct-16-12|| ||FSR: <Olavi> Thanks. I have submitted Yilmaz-Kouatly to chessgames.com.|
|Oct-16-12|| ||Olavi: And this came to mind, fits your collection: M Stean vs Geller, 1975|
|Oct-16-12|| ||FSR: <Olavi> Thanks again! But I wonder whether 11.Kd1, as in Baklan vs Ftacnik, 1998, busts the line.|
|Mar-20-15|| ||psmith: This is weird. The score is now correct but the opening explorer (today's opening) still thinks this is 11... gxf3.|
