What time control was this? Important factor in decision making. Also, don't suppose you could post the PGN -- I hate not being able to flick back and forward
I'm gonna go for about 1600-1800 lichess, just because Nh5 from black feels a bit of a nothing move, and while 15. Rad1 for white gives a discovered attack with the pawn recapture, it gives an isolated pawn and the queen can just move.
