Key Ideas
- ♟White plays Bf4 early regardless of Black's setup
- ♟A system opening — learn one setup, play it against anything
- ♟Solid, low-risk, positionally sound
♔ Plans for White
- —Set up with d4, Bf4, e3, Nf3, Bd3, Nbd2, c3
- —Castle kingside and play for a slow buildup
- —The Jobava London (Nc3 instead of Nf3) is more aggressive
- —Break with e4 when well-prepared
♚ Plans for Black
- —Challenge with …c5 to attack the d4 pawn
- —Play …Bf5 or …Bg4 for active piece development
- —…Qb6 hits b2 and pressures the center
- —Set up …e6, …Bd6 challenging the f4 bishop
⚠️ Common Traps & Pitfalls

If Black plays bishop d6 early, White can avoid the trade and maintain the bishop pair by retreating to g3.
