This is a position in Sicilian Najdorf. White decided to quickly aim for castling queenside and played an early Qd1-d2. Whites latest move was Bg5-h4, keeping the pin on the black knight. Perhaps white wants to castle queenside and then play e4-e5. The other option is to go for the more standard f2-f3, g2-g4 and g4-g5 and similar pawn pushing ideas. But black probably had some ideas behind h7-h6, right?
