Sally Simpson: Good spot DCG.
Slight surprise Ragger missed it, but there again I don't know the time situations. I say 'surprised' because he knew the fortress theme. (I'm sure all good player's do, but knowing and then putting it into action what you think you knew into an OTB game are two different things.) Ragger went for it as Black in his game v Tadej Sakelsek in 2005 but the conditions were not right. Sakelsek - Ragger, Young Masters 2005. (Black to play)  click for larger viewBlack cannot quite set-up a fortress.
He played 104...Kh6 ready to answer 105.Qxf7 with 105...Rg7 (just as you show above, but of course White played 105.Kxf7. So we have KQ v KR.
I had to that once in a crucial OTB game, I did it, but my opponent made a tactical slip. It's not easy v a good player. (especially with a sniggering crowd looking on thinking I'm going to blow yet another theorectically won ending.) The proof is in this actual game. White finally mated Black on move 154! If my maths is correct (Endings and Maths are the bane of my life) that is just one move away from the 50 move rule. I may be wrong about the 50 move rule because FIDE (I presume to justify their existence) keep tampering with things and I know round about then because computers where finding better defences to certain endings the 50 move rule was shelved for a while.
I don't know if the KQ v KR came into this category.
