13.f5!?N An inspiration from the above mentioned game. When preparing for the game, I was intrigued by the fact that White played f5 ( giving up control over e5)restricting the ¥c8 and proceeded to advance on the Kingside quite easily. In this specific case, space & manoeuvrebility plays an important role also considering the fact that the ¤a6 will find it difficult to come to the Kingside. And moves like ¤b1!! create a great impression....
