Lost the last 5 games, what am I doing wrong?

I didn't see that 'the game goes on', as it looked like I was 2-3 moves away from being mated, with an extremely vulnerable King. I take your points on board, though, it's hard to evaluate a position without the help of the engine.

I suggest you study for openings a bit. You don't have to remember everything but following some beginner principals improve your start quite a bit:

- Take center

- Develop pieces

- castle

And you should be pretty solid. I can point you somethings in that first game:

8. Bb5, you have full centre control and you can punish your opponent lack of centre control by advancing pawns. Instead you move bishop again. It did not achieve anything and you lost time because you already had move the bishop once. 

d5 and where is that knight able to go?

10.Bd3 after moving the bishop here you have some trouble after Bg4 which was played in the game

12.Dxf3 how did you miss that your queen is protecting the pawn and bishop?

In middlegame you get pretty far by checking these thing BEFORE(!!!) you make a move

- What is your worst piece and can you improve it

- What are your opponents threats/what will you do after opponent makes a move

- Checks/captures in the position and are those any good

- Opponents checks and captures and are those any good

- If you see a good move, pause for a second and look if there is a better one

Commenting here is probably a lost cause, but that is not certain.

If you don't play out positions that are slightly inferior then you will be resigning positions where you are better and do not realize it.

Nowadays a lot of people don't play endgames because they think the game is over before the endgame is even reached.  My openings are not where I shine but I do play out the middle games and thus have ended up in a lot of endgames, usually against opponents that do not have that much endgame experience resulting in my winning a lot of endgames that were only equal at best.

When you are in a weaker position your job is to prove to your opponent the accuracy of Emmanual Lasker's observation that the hardest thing to do is win a won game.  If you do that then you will score much better than you have been.

Or you can resign whenever you are only slightly behind (or even when you mistakenly think you are slightly behind) and then continue asking why you aren't winning.  Remember Tartakower's dictum: you can't win by resigning.

If you don't know why you're losing, why would a bunch of strangers who were not there be able to tell you? We all lose, and most of us are trying to figure out why WE are losing. I just lost 3 out of 4 and the win was a gift that I really didn't deserve. So rather than ask others for an easy answer to a difficult question, I'll just keep pressing the PLAY button until I start winning again.....and throw in a few puzzles and videos as well. 
I've found that there are three primary reasons I lose. 
1. I'm somewhat distracted that day, and just not at my best.

2. I'm playing an opponent who is a better player. 

3. Both 1 and 2. 

And then I review the game and beat myself up for all my mistakes and blunders, and remind myself what it was like being a high school wrestler......there's no easy way to get good at this. You're going to have your face ground into the mat many times along the. way. 

Winning is not the point of resigning. No one has ever resigned with victory in mind. The point is a recognition of a lost game, the willingness to offer the opponent a congratulatory handshake, and the desire to start a new game afresh. 

When I resign, it's with a sense of "He has defeated me". Sure, he could have a mouse slip or other unlikely blunder, but no....this game is over. He has earned a victory by what he's already done even though he hasn't yet checkmated me. 

Others may see it differently, but that's my view. 

WWJD?   I wouldn't question or judge the ethics. Some things are more important than winning a chess game. 

Then you did the right thing.

The post was primarily for the OP that was resigning in even or maybe slightly inferior positions.  Personally I fight on until there are no more plausible resources left.  When I lose it is (barring the rare mouseslip or actual blunder) to somebody that has shown both the ability to get a winning position and the ability to correctly execute the win.  I've had opponents resign when all I was seeing were lines that drew (usually their resignation is because they don't see their resources that hold the draw).

I totally respect your right and your choice to do so.  That's the point....it's a personal choice, not a "right v wrong" situation.
