is another way to play for Black which worried me a bit more, since here it's
not clear for me how to proceed with White. Black is rather passive at the
moment, but once he has developed his pieces he can make use of his pair of
bishops. I believe that White needs to act rather quickly before Black
consolidates in order to keep an opening advantage. Actually simple
development moves might even lead to an advantage for Black, who benefits from
having the pair of bishops in the long term.} {One idea that makes sense for
me is to start with} 7. c4 {in order to be able to use the c5-break at a later
