I'm out of free analyses and can't figure which move was the blunder

I'm fairly sure I pulled something stupid here but can't figure out which move was the snowball that became the avalanche.

Ok that is odd

Your game looked even for a bit and thought you played well for most part. Move 11 was a little blunder of Bd3 which doesn't protect your e-pawn. Better was having your Queen protect with Qd3 or Qd4. This ends up losing a pawn but you were able to bounce back!

A bigger mistake was on move 25, which was a dangerous move with c4 because of the En Passant move that black can do. Since you played c4, black was able to get the en passant and create two threats. One is to have a pawn that could promote in a couple of moves (very difficult to do) and also your bishop is hanging so it's best to move the Bishop after the en passant move.

The biggest mistake was move 26 with bxc3 which allows the Rook to take your Bishop.

The last mistake was on move 48 of Kd3. This allowed the discover attack which the Bishop was aiming at your Rook and their Rook was in the way, so their Rook moved to check your king while their Bishop hits your Rook.

I feel that one thing you could do if you played rapid is to play 15/10 instead of 10 min. When you do this, you should take more time when the game gets a little bit crazy. My suggestion is to take about a minute or two to search for a possible tactic. Moving too fast can result in losing a chess piece very fast. You should only start to move faster when under 5 minutes left.

I know your getting better with tactics but I do have some videos and puzzles that can boost your tactical awareness. Check out the google slides and let me know if this helps. Best of luck to ya!

Thaaaaanks! I really appreciate you taking the time to do a long detailed analysis! Much appreciate the tactics course too!

Hey, btw, I have premium on my other account (this account is using a gifted trial) so if you need analyses just hmu.

Yaysies thanks!

Here you go, I hope you will find it useful.

Obviously, 11. Bd3 loses on the spot because you gave up a pawn. You now have a lost position but you already played very badly by swapping off in a way that helps your opponent.

25.c4? was a blunder, 26.bxc3 was a bigger one.

If you want to analyze games on your own:

1) For Windows, download Chessbase Reader 2017 from here: https://en.chessbase.com/pages/download. Then download Stockfish from here and install the engine into Chessbase Reader: https://stockfishchess.org/download/

2) On a Mac, you can download the Stockfish App: https://stockfishchess.org/download/

3) On iOS, install the Smallfish app.
You can input the moves of your game into these and it will give you an evaluation of the position. I'd say at least 90% of our mistakes are tactical so an evaluation changing by plus or minus 1 in a single move usually means a blunder on our part.

Ooooo thanks. This illuminated a lot of things. Taking stuff in the middle with a knight like this is a big weakness of mine I've realized.

Oopsey. True. I don't know why I played in such zombie fashion.

Thanks. Gonna spend a bit more time analyzing what I should have done instead of those.

bxc3 was the blunder. You hung the bishop while taking a pawn.

Instead of c4, anything else was okay. Just move the bishop anywhere where it's safe.

Also, the most important question: did you forget about en passant? Or did you think that it's possible but it's okay for you? These are the questions that you should try to answer for yourself.

Yup. I completely forgot there was such a thing as en passant.

You're welcome. That itself didn't lose the game, just an observation that might be useful to you.

Basically, previous mistakes are enough to lose the game on a higher level, but after 25. c4, it is certainly a clear win for black. You are either a few pawns down, or as in your case, a piece down after a second blunder afterwards.

Losing a pawn is not losing on the spot in the opening unless you're over 1800 elo. For beginners, you got to find the pro's and improvements in their games. Some of those trades after the 11th move actually helped made the game even and still had a fighting chances. Just some tactical errors in the middle game and at the end but overall played well.

I mean, even above 1800, you can likely exploit a weakness/get an endgame draw when losing a pawn.

Not in this case, you lose castling rights too
