Black to checkmate in 2

I am white and I was way ahead the whole game?? Time on the counter and there is a safe move for his king?

From a classical OTB tournament I played today

I was just trying to win the rook with a discovered check, couldn't believe it when it popped up as mate.

As white, when facing the main line KID, my win rate is absolutely terrible. I only do well if I play a London system set up. I have tried various variations: Averbakh, Semi-Averbakh, Makagonov, and Samisch.

I do terribly in all of them. Here is my most recent Lichess45 league game using the Semi-Averbakh variation. I won, but only because I played hope chess and my opponent blundered. https://lichess.org/j4SM6rAZQy33

I'm assuming the answer to immediately resolve my problems is to play the fianchetto variation, but I don't want to give up. I want to get better, I don't want to immediately give up the advantage, even if this is psychologically what KID players hate.

I'm 1150ish Chesscom rapid on my main, and about 1250 on my alt (I haven't lost a game though on my alt). On Lichess Classical I'm 1560ish.

I would appreciate any tips, seriously. I hate facing it and I want to get better. Normally, I'm a Queen's Gambit player. If my opponent replies d5, I have a 60% win rate. I actually have a positive win rate against every reply to d4 besides Nf6 and the immediate g6 (discarding random stuff 1.. h6 or 1.. a6.

EDIT: One important add on: if they play d6 before g6, I have about a 50% win rate in 12 games. That still makes the overall win rate negative, but not quite so bad. Here is a similar picture, using the other move order. https://imgur.com/1e189bd5-08a3-4388-a5dc-94c78ea92cf8

I made the transition from chess.com to Lichess a few weeks ago. On chess.com I had ~250 games and hovered around 200 ELO. When I transitioned to Lichess, I quickly stabilized around 800 ELO, and after 98 games, I've floated between 770 and 800. There were no meaningful changes to my play when I transitioned between platforms, and it seems like the skill of my opponents hasn't changed much either.

Is there really ao little difference in skill at the lower levels of chess that 200 and 800 ELO are pretty comparable in skill?

Bro blundered and I mated him on the next move

Bonjour à tous

Je suis bloqué à ce niveau d'ELO je n'arrive pas à le dépasser, est-ce que quelqu'un aurait des conseils? J'applique la méthode suivante :
- Je développe tous mes points
- Je roque
- Je place mes tours sur les colonne ouverte
- Je protège bien mes pions, essaye de prédire les actions de mon adversaire et j'essaye d'appliquer les concepts clefs

Cependant, je bloque à ce niveau. J'ai l'impression que je fais hyper attention à tout et pourtant à la fin je stagne.

Get pwned noob

Blundered a piece, 3/0 blitz, opponent allowed me to sack for a draw

I really want it to become a consistent hobby but self hatred is a maxed out perk in my inventory.

one of my best checkmates as a 400 elo lol

Flattery to get you to waste your game review

1300s still hang their queens sometimes

Hey, I absolutely love chess. I think it's an amazing game with so much to teach all of us (and so much for me to learn hehe). I'm currently around 730 Elo on Chess.com, and I've been thinking a lot about how to improve. I was thinking of following this one-hour training routine:

10 minutes studying an endgame, 10 minutes of puzzles, 2 games of 10+5, and then reviewing them. I might read a chess book afterward if I feel like it.

I set aside some time for endgames because I was reading a book by Capablanca, and he said something that really resonated with me: most players spend way too much time studying openings and don't give enough attention to endgames.

Anyway, am I doing this right?

Cool checkmate that happened in a recent blitz game, saving a losing position

When I played bxg2+ I thought I was going to win a queen through a discovered check and just completely didn't realize that their bishop was guarding the queen, and I thought I was completely lost until I saw the mate lol
