My first try at the Dutch Defence

I won't bother annotating this as it's way too long. I'll leave it up to you to decide what I did right and wrong. Here it is:

3...Bh6 is not how you play the Leningrad Dutch (...g6, ...Bg7.) Put the bishop straight on g7. But OK, openings don't quite go by the book at your level, and more or less anything is playable.

11...Nf6? blundered the bishop. Here you had the promising 11...Bc6, exploiting the fact that white didn't defend with Bg2 first.

19...Kg7 blundered the knight. 19...Nh5 (going to g7, then e6 or something) or 19...Ne4 (to c5?) were perfectly fine. And why not 20...Kxf6 while we're at it.

24...Qe7 blundered the exchange. (What variety!) 24...Bc4+ would have bought time to save the rook.

26...Qxe4 blundered a rook, but oddly enough it's "better" than 26...fxe4 saving it. After 28. Rxe8, you had 28...Qg3+ with perpetual check by Qg3-h3.

Then stuff happened, you got a queen back, but still down material. At this point you should have tried pushing your kingside pawns to attempt promotion, but the "patzer sees check, patzer plays check" syndrome struck, and you rained checks without really doing much. You traded bishops, which almost lost you the game had white known what to do.

Then 64. Nxg6? gave you a knight back. Looks fairly drawish at this point as you had perpetual check after 66. Rbb7 threatening Rg7. He didn't see it and botched it, giving you back another rook.

After 72. Rb4, he could've drawn it perhaps (the Q v R+2P endgame is ridiculously complicated, where the Q can win or draw depending on the files and ranks of the pawns), but he played 72. a5?? You missed 72...Qa1#. Then he pushed the pawns a little carelessly, and gave you the last rook and the game.

Lmao, I thought something was off with the game. Here's 2 more games I've played using the Dutch Defence since then (and they were before I got your comment). How did I do this time?

First game: your opponent blundered a pawn (8. c4), you gave back a knight (9...Na6), he returned a queen (11. Qb3). Not much to say there.

Second game: Here's a fun puzzle. Why is 11...g5 "winning a piece" not good?

That aside, your opponent donated a bishop and you ended up with a strong attack. 18...Nxd4 was a faster attack than setting up Rfe8 first. 21...Bxf1+ 22. Kh1 Bxh3# you missed.

Let's see. Is it because that 11...g5 will be met with 12. Qg3, pinning the g-pawn and allowing Bxg5? Ok, looks like I had it wrong. But it involved a pin, at least I had tha bit right.
