What do you think about it?



I was so hopeful about I could win, but as you can see, I've lost. I wonder your analyzes, criticisms, advises and determinations.
Dont play unclear things like 12...d4 when you are already clearly better. Instead take the e5 pawn and develop. He has no good place to go with his king, both wings are already weakened by pawn moves.
The computer says 5.h3 was a mistake, but I'm not sure why is it so bad, so I won't comment on it.

7. b4 is not great. It is usually a bad idea to move out too many of your pawns before your minor pieces get in reasonable positions to control the center. These pawns will become targets for the opponent to attack, and you need your pieces to attack your opponent, not just your pawns. Similar comments apply to 11.h4. The reason that 8.g4 is reasonable is because it attacks an opponent's pieces, forcing the opponent to move the bishop again, instead of using that time to develop another piece. I'm not sure why the computer likes 12.g5

9.Rg1 wasn't great. Sure, it gets out of a pin, but black wasn't threatening anything, and the rook isn't any better at g1 than at h1. This almost gives the opponent a free move. The computer prefers 9.Nbd2, which brings out another minor piece, and forces the opponent to move the bishop yet again, or play 9...d5, which kind of wastes time since that pawn went from d7-d6-d5, instead of d7-d5 in one step.

Not sure why the computer doesn't like 15.Bh3+, so I'll skip it.

16.Rg4 was a mistake. The computer says that 16...Bf5 is the best reply, but I think 16...Bxb1 is easier to understand. If white takes the bishop on b1, then black plays fxe5, and black as won a piece. If white instead moves the e5 knight away, then black moves the bishop on b1 away, and again, black has won a piece.

The reason why 18.Rxe5, 19.Bg2, and 20.Kf1 weren't the best seem to be very complicated, so I'll skip those.

Note that black missed this trick, as noted by the computer: 20...Qxf4+ 21.Ke1 Qg3+ 22.Kf1 (or Kd2) Qxe5.

The mess during moves 21-26 is complicated, and involve around the fact that white's king is exposed.

I suppose the 28.a4, 29.a5, 30.a6 plan is kind of reasonable, since it gets something for your a1 rook to do, and it potentially exposes black's king for you to attack, but keep in mind that your b1 knight is still at the starting square.

After black's g-pawn pushing during moves 28-32, white has to be careful not to let it promote. White's last chance for a simple win was 34. Qg1, which prevents g1, once and for all.

My guess is that you panicked after seeing 34...g1=Q. However, if you sum up the piece values (pawn = 1 point, knight = 3 points, bishop = 3 points, rook = 5 points, queen = 9 points), you will see that white is only down by 2 points. And after 35.Rxg1 Qxg1, white is up by 2 points, still having an advantage. The computer also says that white quickly checkmates black.

During moves 35-37, the computer says that black can checkmate white. (Neither king is very safe during that time.)

Not sure why you played 38.Qxa7+, which loses a rook for a pawn. White was still only 2 points behind, which the computer says is more than compensated by the fact that black's king is exposed. Furthermore, 38.Rb5 just outright wins the queen in exchange for a rook.

From move 40 onwards, the chaos has stabilized. However, if you sum the piece point values, you'll find that black is 6 points more than white, which is crushing. This eventually led black to win.
You play too fast.
This is a 15+15 time control, so you should have thought about 30 seconds per move.
You have 8 useless minutes left on your clock when you are checkmated.
Think longer, especially at the begin of the game.
2 c3? is passive. Why? Pawn d4 is protected.
3 Be3? is awkward: you block your own pawn e2. The only way to develop Bf1 is then g3 and Bg2.
5 h3? is weak: you lose the bishop's pair, your pawns get shattered and you king becomes vulnerable.
6...e4! wins for black because of the threat 7...Qh4+. You still have 15 minutes on your clock and a lost position…
12...d4? instead of 12...Nxe5! brings you back in the game.

More errors follow from both sides and the probable outcome of the game swings back and forth between both players.

So play slower, use your available time.

You play too many pawn moves!Develop pieces first,then play pawn moves...

You could've played 28.Na3..29.Qg1 etc.Get your pieces out.Trade pieces when you're ahead material (trade pawns when down material)

opponent could've played 22...Qh1+,winning your queen!(Bishop is pinned)

Be careful next time and use your time! :)
