i am tired of this, the whole game i am better

This is ridiculous , my opponent Blunder every move , you can be better the whole game and one move destroys everything , how is this possible that my oppoment is losing the whole game and in the end he founds the best win WTF

I mean, if you didn't spot his plan after move 19, it doesn't matter how well you played the rest of the game, you kind of deserved that

@InnerVoid Please don't feel sad! First understand that each loss helps in learning something new. So take this loss as a learning opportunity and improve your game.

Now coming to the point why this happened in the game, you should understand that the most important thing in chess is the king's safety. It's much much more important than having more pieces. Though you were successful in capturing more pieces of your opponent, at last, he exploited the bad positioning of your king. Since, your queen was also deflected and therefore, she also could not help in saving your king.

So instead of feeling sad, always keep looking for the safety of your king even if you are ahead of your opponent by many pieces. Then, a frustrating situation like this will not arise. I hope you will no longer loss a game like this. :)

3# thank you

It's an old saying that the game is won by the person who makes the second to the last mistake. Frustrating, sure.

I'd say that on move 6...0-0, you castled into an attack. The computer does not mark that as bad in any way because the computer knows how to defend that resulting position! You had problems defending the attack. So for you, probably better would have been 6...Ne4 followed by ...h5. You could then retreat the Knight to f6 and have 3 units protecting g4 for when the attack comes on your h-pawn. You'd wait to castle until the situation on the kingside is resolved to where you can handle it. Your counterplay will come soon enough.

You did a huge blunder and you deserve it.
