I mainly looked at the second game. Forgetting the intricacies of the French, if you go to the position after black's 13. Bc5 then the position is reasonably level for players of your rating.
So I don't think you need to worry too much about the first 13 moves (which is not to say that they were perfect).
After 16. ... b6 you play 17. Ke2 (see below).
I am not sure about Ke2. What worries me most is your comment about a pawn storm on the kingside. You just blocked your g pawn with Ng3. But moreover, what are the pawns and bishop/knight going to do. Without queens on the board you are simply not going to mate black quickly. You need to be thinking now about what sort of endgame you want to play. Would it be better to play Bd2 and then O-O-O? I think that is what I would do.
You agree that 19. b4 was a mistake and loses a pawn.
The above position is after black has played 23. ... b5. Again you are talking about your kingside attack. Look - it is just not happening. Not now. Not ever!! Without queens you can forget that sort of stuff. And it is not the case that you are lost otherwise. You are a pawn down. Even at 1800 people can recover from that. Certainly at 1100 it is not a problem if you play well. But notice that whereas you have romantic ideas of a kingside pawn storm (probably because you watched too many videos by GM Simon Williams - who is wonderful by the way!) black is grinding you down with simple tactics. Already black has won one pawn. Now he is threatening to play Nb3+ and win the exchange on a1. By comparison you are not threatening any tactics. Rather than a pawn storm you should be thinking about how you win that pawn on d4 which looks ripe for plucking.
After 24. ... Bxg2 you lost another pawn. The thing about this one is that you saw it earlier and didn't even mind because you thought you could exploit the half-open g file. So now you are two pawns down and the game is slipping away.
The next position is after 29. h4
After 29. h4 you have pushed forward on the kingside. You have quite a nice knight on f6. But notice you are not really going to get anywhere. Meanwhile you have not put any pressure on that d4 pawn. And you have your own weaknesses such as the f4 pawn. I wouldn't play 30. Kc3. Firstly, black can play Rc8 and that is nasty. But also because of the worry about f4. 30. ... Ra4 is quite a smart move by black though. I am sure he was thinking about your f and h pawns.
Now you are in a whole lot of trouble. You need to kill that pawn asap because the black bishop can cover the queening square on d1. However, even after you play 33. Rg2 black could just play Rxf4 and scoop up your kingside pawns, such is the weakness in your position. However, black's last 5 or so moves are exemplary technique.
You lost almost every tactical battle in this game.
How to do better? Well, tactics trainer on chess.com if you have access to it. But also I think you may be over-thinking things. Rather than going for romantic pawn storms you should be thinking about much more modest ambitions such as how can I win that d pawn?, where can I safely put my king?. how can I improve the activity of my pieces? I hope this helps. It's just my view. Others may think differently.
Thanks for sharing the game. I learned a few things myself by going through it.
Lately I feel like I have hit a peak in rating and I feel stuck frustratingly. I just played two of arguably some of my best games, and yet it felt like a struggle the whole way through. I felt I played the right strategies and ideas I needed to for the openings but I felt out of my league against my opponent. I just need some general advice of what I am doing wrong with my chess. Is it strategy, tactics, or is my play just so bad that I am breaking every fundamental rule of chess. I feel like I should at least be able to hack it with the 1400 players but its just overwhelming for me at the moment. The two games I am posting are 15|10 games. The first I played black with the Dutch defense and won because my opponent was in time pressure. The second I was white and I played against a French Defense where I made an early e5 push (I'm not sure what its called) I have only started looking into the French and the Dutch so my theoretical knowledge isn't as strong as other openings I play so I think they better represent the raw chess player in me. Thanks in advance for any tips.
