A93 Classical Dutch: Classical Stonewall: 7.b3 (1.c4 f5 2.g3 Nf6 3.Bg2 c6 4.d4 d5 5.Nf3 e6 6.O-O Be7 7.Nbd2 O-O 8.b3)

Even if this game doesn't have the usual move order of the Stonewall Dutch, it does end up in a same position as it would after the usual move order 1.d4 f5 2.c4 e6 3. Nf3 Nf6 4. g3 c6 5. Bg2 d5 6. 0-0. But it does miss the last move in that line 6...Bd6, so it must be classified under a different opening. I do have examples of the Leningrad Dutch as well, those in the usual move order but they have not yet been analysed so it will take some time to post even one of them. Until next time my fellow chess enthusiasts. Improved and updated analysis added on December 23rd, 2019.
