My first played game in three months. It's not great or good, but i need some help for my analysis.

http://www.chess.com/livechess/game.html?id=125973361#

From move 1 to 10: We exchange a piece, and build up our positions. I gain space due to my opponent's mistakes.

9.a3 Bd6?! 10.c5 Bc7 thus gaining space from the black position.

11...Ng4? he propably tries some fishing pole - type trap, in this case too late

14.b5! I think this is a good move, not that it only creates pressure on his queenside and on his yet exposed king, at that point i also started to plan ahead my moves with more caution and thought.

15...g5? loses a pawn

Then 19.bxc6 ...bxc6,

This pressurizes my opponent a lot, that pawn simply cannot be protected(see the threat of Nf6+ fork)

20.Qa6! I think that this is a good move, because it puts pressure to the undefended pawn and threats a fork. Propably best options for black would be Ke7 or O-O...

20...Qd5 but he chooses otherwise. This seems like a strong move, but he forgots that i could fork him now.

21.Nf6+ and he resigns.

Did i miss something? What do you think about my analysis, it's my second ever public analysis and i tried only to mention the key points of this chess game. It's probably played on a skill level of a monkey, but at least i had fun.

Noin äkkiä katsoen analyysisi näyttävät oikean suuntaisilta.

Kun mainitset siirroissa 1-10 saavuttaneesi tilaetua mustan virheiden ansiosta voisit tietysti vähän tarkemmin selittää mitä nuo virheet mahdollisesti olivat.

3... Bf5? itse asiassa sallisi valkean voittaa sotilaan joko pelaamalla 4. Qb3 tai vaihtojen 4. cxd5 cxd5 jälkeen 5. Qb3 jolloin valkea uhkaa sekä d5 että b7 sotilaita.

Olet oikeassa, että 11... Ng4? ei vastaa aseman vaatimuksia. Parempi suunnitelma mustalle olisi linnoittaa ja pyrkiä sen jälkeen pelaamaan e5, joka luultavasti avaa e-linjan mustan tornin käyttöön.

En tietenkää voi olla varma mutta minusta vaikuttaa siltä, että 15... g5 oli ihan tarkoituksella pelattu sotilaanuhraus ideana avata linjoja valkean kuningasta kohti. On totta, että tämä tuskin on kovin toimiva idea ja olisi varmaan parempi pelata esim 15... Nf5 ja sitten 0-0. Joka tapauksessa uhrauksen/syötön jälkeen mustan pitäisi varmaan yrittää ottaa avautunut torni-linja haltuun pelaamalla 16... Rg8.

Siirron 16... Ne4? jälkeen mustan peli on toivoton. Kaiken kaikkiaan varsin tehokas peli valkeilta.

Translation?

Ah, we're both finns and he talked finnish to me.

I'll try to translate it for you:

I agree with Shakaali about 3... Bf5? being a bad move. One of my most crushing victories against a higher-rated player came when I played cxd5 and Qb3 in such a game. But you managed to play well and win anyway.

Also, 15... g5 doesn't lose a piece (upseeri), it loses a pawn.

Thank you for that correction. My chess grammar is quite rusty.

I have to keep that Bf5? in mind.
