Train it in TheoriaAbout the Seidel-Hall Attack
The Seidel-Hall Attack answers the threat to d4 in the Teichmann Defense not with 8. Qf2 or 8. Be3 but with 8. g4, letting the pawn go in return for kingside space and play on the half-open f-file. Black most often replies 8...e6, while 8...Qxd4 9. Be3 Qe5 10. O-O-O e6 11. g5 accepts the second pawn. The engine rates the position roughly level, and White scores well online.
