The bishop retreats, although this is not White's only option here.  This
tabiya is the beginning of some heavy theory, but it's also a good point to
stop and do a summary. I have seen many of my students blitz out these moves
without stopping to think deeply about the position. So what is going on here?
White is up a pawn but is behind in development. Black has long term
compensation with more space in the center and better development. However,
Black's a5-knight is misplaced in the long term - a major theme in this
opening! At some point Black will have to think about how to bring the knight
back into the game, probably with ...c6-c5 and ...Na5-c6. White will have to
play passively for a long time, but the extra pawn may play well in the long
term. Which side of this you prefer -- whether you like playing down a pawn
for long term compensation or playing up a pawn in a passive position -- is a
matter of taste.} *
