OTB OVL2 : Draw with black against 1644

After this game i wondered why i didn't see the "winning" move ,

It was because I was focused on a plan and they say "If you see a good move , look for a better one" ... in this game I found a plan and I should have looked for a better plan "

I had superior pieces but I didn't find the right way to turn it into an advantage ... 

My oponent had 'only' 1644 but .. just like me ... over the last 6 months his rating increased with over 50 points and mine over 60
