g7
What's your favourite chess square?

My favorite is the one in the middle.
Ha ha, we had the same thought almost simultaneously.

g5 almost every fun opening line has a piece on g5
ex/ semi slav botvinnik, najdorf poisoned pawn, trompowsky, hopton etc

f4 and f5 of course because my pawns go there in most of my openings. There's something special and very beautiful to positions which have pawns on those squares...
f5 of course
