I'm not sure Black's better here. I play my friends Fritz program and I get positions like this often and if I can hold my weakened King position I get a totally busted endgame.
To free the strong bind White has maybe something like ...e6. Looking for exchanges and mobility without creating a fatal weakness. If that could be accomplished it's probably worth a pawn or so.
White's probably not going to take as it looks like it doesn't help much and weakens c4. Probably won't reposition the N looking for the outpost if...exd5. If it was me I'd probably double rooks on f.
So that allows ...exd5, if takes with N then want to trade your B for the N so maybe ...Be6. N probably doesn't want to retreat and N to 7th doesn't seem too tough. So maybe he finishes doubling rooks so you take and now either pawn recapture allows possible Black pawn push for tempo on White d3B and more manueving room.
But Black still has to deal with the g6 light square weakness and now a very strong White f-file and the d6 Knight but could have some counter chances to maybe equalize.
I took these ideas off an intitial read assuming White had or just about had a winning bind and didn't actually test out any lines so maybe I'm way off but I'm guessing the general idea that Black needs exchanges to free up the position is likely correct.
In the following diagram I was black vs a player rated three hundred points higher than me. I felt good about my position. His light squared bishop and knight are both awful. My knight is on a good square blockading the d pawn and hitting the pawns on c4 and e5. My light square bishop is far superior to his. I stared at the board here for a long time trying to find a sensible plan to improve my position to push for the win. A few of my rejected plans were: bishop sacrifice on h3 because once my queen is on h3 then what? I have no other pieces that can quickly join the attack. I also rejected pushing the b pawn because after the trades on b5 I have traded off his poorly placed minor pieces for my better ones, plus the knight would no longer be blockading the d file. Capturing the f pawn only opens the position to his advantage allowing him to push the e pawn which would bring the light bishop to life on the diagonal against my king. In the end I just pushed my h pawn up with vague ideas of bringing the bishop to h6 or a rook to h8.
Can anyone see a good plan for black from here? Can you explain it in regular language? Thank you.
