Eyeing square d3

Unfortunately, the discovered check made possible by this move is not very useful

I figured the fewer minor pieces white had, the better

Picking up material and creating open files for my pawns to queen

White clearly wants to get rid of some of black’s potential queens

Preserving two adjacent passed pawns

Advances a passed pawn but also enables the black queen to protect the pawn on f7

The white knight is dangerous here - attacks the pawn on f7, denies an escape square for the black king and protects square d3 for a check from the white bishop

Logical attack that buys time

Kg3 would have allowed me to pick up the white rook by Qg5+
