I played today this game and I thing I managed to have a very good game after the opening but I choice an erroneous plan and I lost.So I want to hear some advices about a plan and move especially after the 17 (or outsource earlier) that I thing I played wrong.Fritz says 16 or 17 c5 and I thing white is must better or maybe 17.Qe1 or Qe2.Any suggestions?

cxd5 seems like a mistake as it releases his weakness on e6 and any advantage you

have in the center.

Yes for sure,maybe Qe1 must be better.

Maybe Qe2 or Rc2 with the idea of doubling rooks on the efile.
