i don't know the technique either, but i haven't ever even got the opportunity to fail that in over 30k internet games across random servers. (though most of them were bullet games, admittedly)
Jeremy Silman also doesn't even bother to include it in his "Silman's Complete Endgame Course" and justifies it by saying something to the effect that it's pretty much not worth it - guess it's not a "complete endgame course" after all? :P
i think it was a good book and agree with his opinion, though.
Fair enough. I'm certainly not convinced Ushenina is anywhere near, say, Polgar or Hou Yifan. There were even a few 1800s give or take playing in that world championship.
