This move is not considered to be white's best, becuase it gives up some of white's control of the center. Typically the idea of playing the sharp 5. f4 attack is to sacrifice a pawn in the center for a fearsome attack. I recently got killed in that variation by an international master: [ 8.Be2

This move may be too passive, but white's other options are not too exciting either. [ 15.Be3

A move of this sort is typically iladvised since it takes the pressure off c4, but in this case it may be good because it gives black a decent advantage by force. [ 15...Bb7

Black has a clear edge since white cannot take advantage of the pin. This is probably why my opponent chose the 16. Ne2 line instead.]

Black has a nice position here, but I didn't have much confidence in it looking ahead during the game, because I thought my e4 and d4 pawns might become easy targets for white's bishops. So I was relieved when my opponent played the inferior 18. Be2.]
