1.d4 e6 2.c4 f5 3.Nf3 Nf6 4.g3 Be7 5.Bg2 O-O 6.O-O d6 7.Nc3 { (This position can be reached via different move-orders. It is the critical starting position of the classical Dutch.) } 7...Ne4 { (The English grandmaser Simon Williams calls this the modern variation. The play becomes quickly very sharp in this line contrary to the more positional a5. Anyway this is blacks best chance to equalize as my analysis showed that a slow approach of black allows too much initiative to white.) } 8.Nxe4 { (I consider this the most critical test but also against Qc2, Qd3, Bd2 and Nd2 black has no easy task to get equality.) } 8...fxe4 9.Nd2 { (Ne1 should not be underestimated by black.) } 9...d5 10.f3 { (First e3 is also possible and can lead to a transposition of the game.) } 10...Nc6 11.e3 { (Before fxe4 was considered the mainline but I find today e3 more clear.) } ( 11.fxe4 Rxf1+ 12.Kxf1 { (This refinement to Nxf1 was discovered first in 2013 and played in correspondence chess.) } 12...dxc4 13.Nf3 b5 14.Be3 Qf8 { (The Chech correspondence-player Zdenec Nemec is the last player still willing to defend this line. Anyhow I can't say black's play is a walk in the park.) } 15.Kg1 ( 15.a4 b4 16.Kg1 Rb8 17.Rc1 Na5 18.Ne5 c3 19.bxc3 b3 20.c4 Qe8 21.Rb1 Ba6 22.Bf4 g5 23.Be3 Qxa4 24.Bh3 { (The correspondence-game Pekin,T - Nemec, Z played in 2017 was drawn after 33 moves.) } ) 15...Bb7 16.Qd2 Rd8 17.Bh3 Qf6 18.Bg5 Qf7 19.b3 cxb3 20.Bxe7 Qxe7 21.axb3 a6 22.Rc1 h6 23.Qc3 Re8 24.Qc5 { (The correspondence-game Willmann,B - Nemec,Z played in 2015 was also drawn in 51 moves.) } ) 11...exf3 12.Nxf3 b6 { (Bf6 was played more often in otb but after Qc2 recommended by the engines white is simply better.) } 13.Bd2 Bb7 14.Rc1!
