Always one of my favorites when a player is hyper attacking f2. if Qf6 instead of Nf6, Ng4, then I also play Ne4.

Gains a pawn. It appears black planned to make the dark squared bishop bad. but breaking the pawns takes away that decision, esp. after the fall of e5.

Black clearly intends to continue attacking f2 at all costs.

Loses more material. The game is very much over from here.

Relieves the pin.

Taking the bishop allows white to trap the rook... it will take several moves for black to get his rook out. White can trade down and end it.

Not allowing the pawn break to relieve the rooks shackles.
