2007-12-09 10:11:06LaskoVortex1359Much more difficult than the rating suggests. 
2011-01-28 03:30:00dktransform1602Just as LaskoV says, exactly! 
2011-06-20 01:10:09BernardW1002a kind of "inversion": strong players will find this more difficult than less strong players 
2013-11-24 18:58:25BadMamaJama1284one of those moves that really turns the game around, if you see it 
2016-03-22 20:30:18slowness20141641QGD (Exchange Variation): 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.Bg5 Nbd7 6.cxd5 exd5 7.e3 Be7 8.Bd3 Ne4 9.Bxe7 Qxe7 10.Bxe4 dxe4 11.Nd2 Nf6 12.Qc2 Bf5 
2017-05-14 20:00:58JustDefend1482please explain this to me. 
2017-05-15 23:13:29grom431845@JustDefend, OK. White thinks the e4-pawn is pinned and attacks it by 1.f3 which is a huge mistake. Black takes 1...exf3 and now threatens three things (at least): BxQ, fxg2 and Qxe3+ so he wins the game. 
2017-05-15 23:15:40grom431845If Black tries 2...fxg2 right away, 3.Rg1 Qxe3+ 4.Ne2 defends that Rg1. 2...Qxe3+ wins at least two pawns.
