2009-01-26 11:58:32UriBlass18883.1 seconds got it in the past. second move easy to remember 
2009-05-14 03:08:52rockym1552get into a pin...is ok when you can check (and the pineer is unprotected !) 
2009-07-06 23:22:24tjumen1461super good 
2010-01-26 21:11:00rathkeltair1711self-pin - but really just setting up the discovery - nice 
2011-05-18 22:10:08grom431842The real key is you're UNPINNING that N with tempo to save your R. Nice one. I like that, you unpin the king but self-pin the queen. :-)

2011-11-30 17:31:07SirRick1703this refutation (of Nxd5) is art. Nice descriptions you´ve found! 
2012-04-16 08:51:54chessisajedrez1747The biggest burden of the problem is overcoming the prejudice/bias that we should never get ourselves into a pinned situation. As grom43 well explains, the tempo winning move makes for a practical exception. Instructive.
