I noticed in my game prep Naumkin had done this move in some of his other games, it is a bit cheeky to think he can get away with it here when Black has already started, operations on the queenside, Naumkin agreed with this after the game
14...c4
normal Benoni counterplay
15.Qf4?!
later Naumkin said this was probably a mistake, but at the time it was a bit of a shock (initially) the queen arriving on f4 like this
15...Rab8
I realised the queen on f4 actually posed no threat so I could just get on with one of my normal Benoni plans of b7-b5
