📘 10.Qg4!
A multi-purpose move:
1- To prevent the development of the black king's bishop.
2- With the idea of Qg3, offering to exchange queens.
3- After the exchange on g3, the h-file will be opened for white. If black refuses to trade, he will lose a tempo. it means he shifts his queen to a less useful square.

📕 1.Bxd5!
Black's pieces have no proper coordination at the moment and White exploits it.
1.Rfe1 or 1.h4 allow Black to obtain counterplay: 1...Nxc3 2.bxc3 Qb2.

📕 1.Be4!
Black has only to play Bc8-d7-c6 to get into good position. The queen is misplaced on b6, where it doesn't cooperate with minor pieces, and the dark squares on the kingside are weakened. White uses his advantage in development to seize the initiative. White wants to exchange Black's pride - his knight at d5, and then the weakness of the dark squares around the king will be more perceptible.
