I played a game today where I feel that I had a nice positional advantage (the computer supports my opinion) but I only managed to draw it in the end. This is the position that I consider to be critical:
[fen "2bq1r2/1r1np1kp/pp4p1/2pP1pP1/2P1NQ2/3B3P/PP3P2/R3R1K1 w - - 0 1"]
I am playing White. Here Black played has just played ...f5 and my following moves were Ng3 and h4 (after Rf7). I still had some advantage at that point according to the computer but I lost it a couple of moves later after some inaccuracies. What plan should I have followed? What are White ideas to win in this position?
