Maybe White should wait a little longer before closing the center.

The idea, I think, is to remove White's option to move the bishop to the g5-square. 8.Be3 is not attractive now due to 8...Ng4. Apart from that, the h7-square can be useful for the knight when preparing the typical f5-break, as we will see in the game. 8. f1e1  8... b8d7  9. e2f1  9... b7b6 [%c_effect b6;square;b6;type;Interesting;persistent;true] An extremely rare move.
