What Made This Move Good
You correctly saw: That the c8 needed a useful square before the e7 pawn moves to e6, which would otherwise trap the bishop behind the pawn chain. By playing Bg4, you solve your development problems early.
📚 Takeaway: In positions with multiple good moves, trust your style—whether you choose to be aggressive or solid, both can be right!
