Choices of material over position Allowing Counter-Play
Opening Lines

if we look at the position 1st we see that
white has castled; black has not
black's Queenside pieces are not developed
while white's pieces are almost fully developed
black could capture the b-pawn; black has little
to fear from Rb, which perhaps would be something
 to worry about if a) his B on c8 were developed and
b) the c3 knight were not threatened (after the b2
pawn is taken
what is also interesting  is that white's e-pawn
is also weak, and the Bishop on g7 is on a very
strong diagonal, in fact if the N on f6 were not there
then black would be threatening the d4 Knight
