Found 9 crucial moments (2 blunders, 7 missed opportunitys).
You had a chance to play Nxd4! This opens the position and wins material. If White responds with Qxe7, you then play a6. White's best response is Ba4, completing the sequence. This capitalizes on the hanging pawn and gives you a strong advantage.
You had a chance to play b5, a strong positional move! This move would have challenged White's control of the center. The engine suggests the continuation Bd3 Rc8 Nd2. This line aims to improve Black's position considerably.
BLUNDER: You hung your pawn. The opponent can simply take it with Rxh7. Kf6 worsens your position. The best move was Bxc7, followed by Bxc7 Bxf8+ Kxf8 f3.
Rook f6 is a mistake because White can play Rc5, followed by Re6, and then Ra5, eventually forcing Ke4. Rxc8 is superior because after Rxc8 Bb4 Rc2 a4, the position is more balanced.
You had a chance to play Rxf2+. This excellent move is more than just a check! It forces Kg1, and then you can play Ke4, activating your King. The engine suggests Bg7 next, after which your bishop is defended and becomes a major player in the endgame. This leads to a much stronger position than Rxb4.
You had a chance to force a checkmate with Ra2! This immediately threatens your opponent's king and forces a response. If your opponent plays f4, then Bxf4 wins because of the threat to the Black king. If your opponent then responds with Ba3, you still have them in a forced mate situation, as the engine suggests.
You had a chance to play Ra2, forcing a checkmate. This immediately attacks the king. If you had played Ra2, the best response is f4. Then Bxf4 wins material. Finally, Kxh5 continues the attack and leads to a forced checkmate.
You had a chance to play Ra2! This forces a quick win. While Kxf3 is safe, Ra2 immediately threatens mate. The best defense, Bh6+, delays the inevitable. After Kf5, Bg5 is forced, and you are completely winning with a forced mate! This position shows how active threats can be more powerful than simply capturing material.
You had a chance to force a checkmate sequence with Qd7. This immediately puts the Black King under pressure. If Black responds with Kg8, then Kf6 forces Kf8 and checkmate.
