Defensive resource

I think everyone will be tempted to play g6 in this position. But g6 throws the advantage. Black has an insane resource to draw the game there

It is tempting to take the rook and promote to queen, but If white still has castling rights 0-0-0 to prepare Bc6 discovery check seems more tempting to me. Even if the castling rights are not there I still feel Rd1 Bc6 is more threatening.

Ohh I see now, You said throws the advantage then in that case, this is a great post. The king is very open after an e3 pawn push. I like these drawing techniques.

My first intuition was to castle queenside. No idea if that's correct.

I would want to use the engine here. This is an insane position especially if it was in a bullet game.
