   Jul-17-18 A Rotstein vs Y Gonzalez Vidal, 2005 (replies)
sombreronegro: heavy artillery.
   Jun-06-18 B Adhiban vs D Andreikin, 2017 (replies)
sombreronegro: That is actually very pretty. The knight is immune on c2 because the bishop covers the 2nd rank on the a file . This allows the knight to control a1. Not too easy but really pretty logic.
   May-25-18 M Antipov vs S Ivanov, 2017 (replies)
sombreronegro: Seemed easy for Friday. A temporary queen sack leads to simplification with 2 pawns up. The two pawns working to control e6 and e7 is interesting though. A good pattern to keep in mind.
   May-20-18 A Kats vs C Baginskaite, 2012 (replies)
sombreronegro: So easy , once you realize the G1 rook is the corner stone of the position that is. So easy in hindsight as always. Its the old over loaded piece gag. It can check the king, but it cannot leave the back rank for any old piece. It defends the rook on e1 and its the primary ...
   May-01-18 J Moreby vs P Roberson, 2017 (replies)
sombreronegro: Nice pin at 35. R x g3... too bad about the skewer and mated part though...
   Apr-27-18 S Brenjo vs D Bojovic, 2008 (replies)
sombreronegro: There were so few good moves for white here that giving back the exchange to compromise the black king safety was easy to see. The other rook eyeing d7 draws attention until you realize moving it off first rank leads to mate in one.
   Apr-24-18 M Bartel vs A Belezky, 2008 (replies)
sombreronegro: Boy that was dumb. I found the moves but kept picturing the pawn capture on move 3 without just pushing the pawn.
   Apr-19-18 S Gupta vs F Grafl, 2016 (replies)
sombreronegro: Too passive in the center allowing white to crush the main defensive unit the bishop. 11 ... Be6 and its just a squeeze. Saving it once just allowed the g file to be opened where it was pinned and crushed. brutal
   Apr-18-18 Spassky vs Fischer, 1972 (replies)
sombreronegro: 15...d5 was a horrible move , especially because he was forced into it.
   Apr-18-18 Svidler vs Kramnik, 1999 (replies)
sombreronegro: lots of resources with the two bishops and the rook confining the king to the h file. A wed puzzle made it an obvious queen sac.
