[...] 1.♘f3 d5 2.c4 d4 3.b4 f6 Not a very frequently played position in corr-chess 4.e3
(4.a3 e5 5.e3 a5 transposes below) 4...e5 5.c5
(5.b5 ♘h6 6.exd4 exd4 7.♗d3 ♕e7 8.♕e2 ♗f5 9.♗xf5 ♘xf5 10.d3=) 5...a5 (5...dxe3 6.fxe3 a5 7.d4 File)
4.♕a4 ♗d7
4...♔f7?!5.c5 e5 6.e3 is not a position i would ever enter with black
5.♕b3 e5 6.e3 is interesting, but i think not very promising for white
5.a3 this is interesting too 5...a5
5...c5 6.d3 dxe3 7.♗xe3 cxb4 8.d4 bxa3 9.c5 white has the better chances for sure
6.b5 d3!? (6...c5 7.d3 ♗d6 8.g3 ♘e7 9.♗g2 O-O is a normal but complex position) 7.♗b2 ♘h6 stopping all Nxe5 ideas and simply developing (7...e4 8.♘d4)
7...a4?!8.♘xe5 fxe5 9.♕h5 ♔e7 10.♕xe5 ♔f7 11.♘c3 ♘f6 12.♘e4
8.♕b3 e4 9.♘d4 a4 10.♕d1 (is interesting to explore 10.♕c3!?) 10...c5 11.bxc6 ♘xc6 12.♕h5 ♘f7 13.♕d5 f5 14.f3 ♖a5 15.♕xd8 ♔xd8 16.fxe4 fxe4 17.g3 ♘ce5 18.♗c3 ♖c5 19.♗g2 ♘g5 20.O-O ♗e7 seems white doesn't have something here
5.♕b3 ♘h6
5...c5 6.bxc5 ♗xc5 7.exd4 exd4 8.♗e2 ♘e7 has been played a couple of times but it doesnt give white any ground to fight for an advantage
6.♗e2 ♘f5 (6...♘c6 7.c5 a5 8.b5 ♘b4 9.a3 ♘d5 10.♗c4 a4 11.♕a2 is interesting too) 7.O-O a5 8.b5 ♘d7 9.♕c2 (9.exd4 e4 10.♖e1 ♗e7) 9...♘c5 10.exd4 ♘xd4 11.♘xd4 ♕xd4 12.♘c3= black has easy play
5...d3 6.♕a4!? (6.♕b3 e4 7.♘d4 f5 8.g4 ♘h6∞)
6.♘c3 ♗e6 (6...a5 7.♕a4 ♗d7 8.b5⩲) 7.♕a4∞
6...♗d7 7.♕b3 e4 8.♘d4 ♘c6 9.♘xc6 ♗xc6 10.♘c3 white is doing fine here
