Question about the computer's valuation My friend recommended me this good community. However, I'm new to this format so I had no idea about including a chess game in my text. By looking at the previous questions, there should be some way to include my game, but I couldn't find this so instead I brought the picture of the part I was wondering about.
Why the above position almost winning for me? As indicated in the picture, chess.com's depth 18 engine is marking it as -7.4, but I have no clue about it. I couldn't find any tactics nor throughout the computer's suggestions.
Some information about that would help you answer: My chess.com rating is at 1100~1200, and been playing chess for about six months. I have mo experience in learning chess theory, only solving puzzle rush every day.
White can't defend the a3-pawn. The White king is defenceless on the queenside, and you have the knight on a great outpost near the White king, the bishop a mere ...d5-d4 away from joining the attack. The Black queen is entering the fray either via Qb6 or Qa5. both Black rooks can participate in the attack through Rc6-b6 or Rc6-a6, or along the c-file.
Basically a chess engine can't find a way to defend against the oncoming attack along the a- and b-files aimed at the White king.
Black's immediate threat is to play ...Nxa3 threatening ...Rxc2+. White defends that by playing c2-c3. White's best option at this point is to evacuate the king over to the kingside, so White's best moves of Rd1-f1 are there to clear space for the White king to walk from c1-d1-e1-f2. While he's doing that, Black is bringing his pieces quickly into White's half of the queenside attacking the king directly.
