I have a win and a loss (both against high-rated players in a tournament) linked below. I'd like to know what I did well in the first game and what I did wrong in the second.
http://en.lichess.org/W481eeQ0/white#61http://en.lichess.org/MD8G72EG/white#21Move 14 you won it on Game #1 when he took your Knight with the rook on the A file, moving to b8.
You lost the 2nd game on the 2nd move of the game. You have have moved Bb7. When white opens with e4 its a force loss for white.
I'm not top 100 or anything in Antichess but I can at least give you some tips and play a few casual games with you. I'll do a couple lines that I know are losses and see if you can figure them outand try and tell you what you do wrong.
I am not sure how strong it is, but one thing you could do is to download and compile a copy of Nilatac (
http://catalin.francu.com/nilatac/) and then copy and paste the pgn from lichess into the engine. One unfortunate thing about suicide/losers/reverse/backwards/anti chess is that, from an engine's perspective, there are often long forcing sequences. This means that engines might need to go to a higher depth in order to properly assess some lines. Since the analysis that lichess does is fairly low depth anyways, it might be better to run it on your own computer even if lichess does implement an antichess analysis feature.
In first game:
At least, you blundered twice in the game.
a)5.Na3?? Bxa3 6.Bxa3 Qe7??
6...Nc5 was much better here, and after this:
a1)7.Bxc5 Qxd2 8.Kxd2 Rb8
a2)7.Bxc5 Qxd2 8.Bxa7 Rxa7 9.Kxd2 Rxa2 10.Rxa2 Ba6
Both of them were easy forced win for black.
b)10.Nf3?? Ne5 11.Nxe5 c5?! ... 14...Rab8??
10.Nf3?? was clearly blunder.
Black could play 11...h6 12.Nxf7 g6 13.Nxh6 Nc6 14.Nxg8 Ne7 15.Nxe7 Bd7 ...
But instead of it, black played huge blunder at move 14.
Black still had chance to play with big advantage.
For example, 14...a6 15.Nxc5 Rab8 16.Nxa6 Rb4 17.Nxb4 ...
15.Nxb8 ~ 16.Rb1 ~ 17.Ke2 You were playing so well around here.
But, in endgame you could play more clearly.
For exmaple, 18.Kf3 Rxh2 19.Ke4 Rxg2 20.Kf4 Rxf2 21.Ke4 Rxd2 22.Kf3 Rxc2 23.e4 Rxa2 24.Ke2 Rxe2 25.e5 Rxe5#
Your playing was dangerous, but congrats for a great win.
In second game, your blunder was the first move, as other people wrote.
I hope you learn something from this long terrible sentences :)
knives and link said it all :)
this is what wizard 3.1 (free version) says about your games. the annotations are mine, though numbers are computer evaluations.

26. e7 (+2.67) Na8?? (White wins in 11 moves) (Best: Ne6 +2.67)
27. e8B (White wins in 11 moves)
and the game plays itself from there.
no point in doing the second one. 1. e4??? is trivially lost (black wins in 16 moves with 1... b5 2. Bxb5 Nf6!) as others have told you
