   Jan-22-13 Mackenzie vs Mohishunder, 1857 (replies)
 
jpolchinski: Mohishunder has 449 games in the database, and this is the only one not vs Cochrane.
 
   Nov-14-12 Velicka vs Jansa, 1997
 
jpolchinski: After <chrisowen>'s(!) +2.27 line I beat Crafty with 27 cxd5 bxa2 28 Nf4+ Kg7 29 g6 Nf6 30 Qg5 Rdc8 31 gxf7+ Qg6+ ke7 32 e5 Bxg7 and now several moves win - exf6+, Qxf6+, exd6+. Just keep pushing those pawns!
 
   Oct-07-12 K Mokry vs Gheorghiu, 1985 (replies)
 
jpolchinski: <LTJ> Your Qxh5! line line after 22... Kg8 is nice. 23 Qg5 Nxf6+ costs W a needed tempo, and 23 Bxd8 is not so immediately decisive.
 
   Sep-09-12 G Vescovi vs Leitao, 1998 (replies)
 
jpolchinski: If 34. Qxf3, R8e3 35. Qf1, Rxa2 leads to zugzwang, e.g. 36. Rg2, Rxh3+ 37 Kg1, Bb6+
 
   Aug-01-12 DeFirmian vs A Rustemov, 1999 (replies)
 
jpolchinski: <gofer> Thanks for the clue, a nice line!
 
   Apr-06-11 M Bab vs Dus Chotimirsky, 1911 (replies)
 
jpolchinski: I thought 31 Rg1 gave W an escape square, 31 ... Rh3+ 32 Kxf2 Rh2+ 33 Kf1. But 31 ... Rh2 seals in the WK and it's mate next.
 
   May-03-10 O Sarapu vs Z Frankel, 1962 (replies)
 
jpolchinski: The desperate 29 ... Qh2+ 30 Kxh2 Bd3+ 31 g6 gxh5 stops the mate at the cost of a piece.
 
   Apr-12-10 Polugaevsky vs Smyslov, 1960 (replies)
 
jpolchinski: <Jimfromprovidence><The physicist?> Yes, actually. But a knack for theoretical physics doesn't seem to carry over to chess.
 
   Dec-10-09 Uhlmann vs Larsen, 1971 (replies)
 
jpolchinski: If 42 ... Kxg5, the followup takes some calculation, I think: 43 Rh5+ Kf6 44 Rxd5 cxd5 45 Kxd3 a5 Now, W can't make the break 46 b4 because of ... cxb4 47 axb4 a4, and one of the B pawns will queen. So 46 b3 Kg5 47 Ke3. Now, any B pawn advance loses, so the K must retreat and ...
 
   Nov-04-09 T Abrahamyan vs I Zenyuk, 2009 (replies)
 
jpolchinski: What if 36 ...Kxf6 37 g7 Rg6?
