🔺In this position, h4 with the idea of h5 was a proper move to deflect the black's knight from g6 square and e5 pawn.
1.h4! N.h4 (N.e5 2.Qg3! with the idea of Nf6+-) 2.Qf7+ Kh8 3.Nf6!+/-🔺

🔺Qe3 was an interesting move to launch an attack on the kingside. Transfering rook or queen to the kingside via 3rd rank after playing Ne5 is a typical idea in Isolated Queen Pawn structure.🔺
🔺As black is significantly back in developnent this sacrifice makes sence. White will have enough compensation if the sacrifice is accepted. If black does not take the bishop white will have strong attack by playing Rhf1, B.d7 or e5.🔺
🔺black has played accurately here and with active moves he tried to not give attacking chances to white
1...Ne8! 2.Nf5 Ra4! 3.Ndf6 -/+🔺

🔺After some weak moves by black in the critical moment of the game, white managed to find the winning combination!

🔺The idea of putting the queen on d3 to support a knight on d5 is common, it hasn't been seen in top level chess in this particular position.🔺
🔺
One of White's main plans in such positions is Qd2 with the idea of Na5 and b4, and generating a pawn majority attack in the queenside. Giri came up with an interesting plan. He played g6, now if white sends the Knight to a5, he would be able to send the knight to f5 via g7 and if white keeps his knight on b3, then he will go for f5 and continue his attack in the kingside.🔺
