Guys
Post your games here :)

My opponent wanted to be up a pawn and hung onto it for too long. He was eventually gonna lose a piece no matter what he did

I just played a nice game as black recently with a lot of tactical moves. I probably won't write bigger explanations like I normally would but I will show the tactics on the board to cover that(I'm kind of too lazy to spend half an hour just typing lol).

you certainly did well spotting your opponents mistakes but try not getting yourself into those situations where you weaken your kingside and damage your own pawn structure(that was the one inaccuracy you played).

I'm not sure how 5. Nc6 weakens the kingside.
If your opponent were to play knight e5 they would've been able to start an attack and damage your kingside because of the pin. Not only that but doubled pawns are always a weakness and your king becomes more open and vulnerable to your opponents attacks. Instead they moved their bishop back which ended up giving away their entire advantage and from there you smoked him.

And that was the queenside. (and doubled pawns aren't always a weakness)
mb sorry. Yes doubled pawns aren't always a weakness but they would be in this situation and while they aren't always a weakness from the start longterm they can become a loose end.

When they capture it goes from 0.8 -> 0.2, which means a draw and is equal to me playing e4.
no no. You dont capture right away. There is a follow up on the review as well and if you pay attention it stays at 0.8 the whole time. right now i dont expect you to find those sort of sequences because they are kind of hard to spot and you are a beginner(tell me if I'm wrong. I got that idea simply because it says you joined 6 days ago). I'm just saying don't make moves that could end up leading to situations like that.
Wow you reply so fast
I mean I kinda have to...
