I'm white. The time controls are 15+10. Here's the game. lichess.org/nh5Y4wnE
After winning a piece by move 9, I was pretty sure I was going to win, but I had trouble finding good plans, got into time trouble, and somehow ended up losing. Could any of you take a look at what went wrong?
Here are some specific questions I have:
- On move 14, I spent some time trying to find a plan. I didn't like how black had many pawns in the center, so I decided on a plan involving the moves Ne2, c4, b3, and Bb2 in order to gain some control of the center. Is this plan good or not?
- I thought that 20.Nc3 was bad, given that the knight moved again later anyway. After the game, I thought that the best move was 20.Rd2, possibly continuing with 20...f5 21.g3 e4 22.Bg2, when the e2 knight is well placed to take advantage of the pawn structure. However, 20.Nc3 turned out to be the computer's second choice, so it's actually pretty good. Why is this the case?
- During moves 21-24, the computer is suggesting plans involving b4. Why? I thought I had to deal with black's central pawns somehow.
- The computer suggests 25.g3 and 27.g3. I considered playing g3 at some point around those moves, but I rejected this plan since making weaknesses when the opponent might have an attack on my king seemed terrible. Why is it a good idea?
- I knew that my 24.Ne2 and 25.Nd4 plan seemed dubious, but I couldn't think of any other plan. I'm having trouble finding good squares for my pieces. What kind of setup should I have done?
- During the game, by move 27, I was already preferring black, and I thought that if I did nothing, black would win with some kingside attack. So I played 27.Rd5, giving up an exchange, which I thought was the only was to keep the advantage. The computer doesn't like this, suggesting (again!) 27.b4 or 27.g3, when white is still winning. Why is black not having sufficient compensation for the piece? And what's up with these b4 and g3 ideas?
- I couldn't play 30.Bxa6 due to Ra8 and Rxa2. I missed the idea of playing 30.a4, forcing a5 since black cannot defend both e4 and a6. But what's up with 30.b4 again? I thought I'm supposed to keep the position closed so black's rooks cannot get active. My idea of 30.f3 was to open up the d3 and e4 squares for my minor pieces, but apparently it was bad. I knew that putting pawns on light squares is bad for my bishop, but I wasn't sure how I should have coordinated my pieces.
- Was my 31.Na3, 32.Nb1, 34.Nc3 maneuver a good idea?
- Why is 35.Bd3 an inaccuracy? Why is the position after this move equal?
- After I let the computer think about the positions after 47.Nxb4 but before 49.a4 for a while, the computer says that it was OK, and the position was equal. Why is black not already having an advantage due to the king becoming more active?
- What's wrong about 49.a4? I thought I'm supposed to push a passed pawn.
Please ignore my moves after 49.a4, since I started making mistakes due to time trouble. Also, if there's anything else you noticed, please tell me.
