Wow, I can't believe I missed that!?!

19.Nd5  Nxd5  20.Qxc6  Kf8  21.Qxd5.....

Please explain Nd5, I don't get it.

I will try again

f3 of course is bad.

your first 9 moves, 7 pawn pushes and 2 queen moves.  not good.  you need to develop pieces.  you cant win the war if you leave your army at home.

i liked the queenside castle move.  makes kingside pieces more active and gives you more protection

19. Ne4??  a terrible move even though it leads to your win.  Better would have been Nd5  It wins without the mistakes.  Take a look at it and see if you find what i mean.

Basically you need to study your openings.  Your tactics and combinations look good.

  I dont know where my comments went but i dont see them.

2.f3 doesn't strengthen your defense, it weakens your king.

If you're still thinking not taking the piece was right, then you seriously underestimate the advantage of a piece.  But what is appealing about playing passively?  Passivity and defense are two very different entities, as I have said before.  Passivity is placing your pieces on inactive squares, defense is neutralizing the attack your opponent formulates.

I will comment on your responses later, but my typical startegy is to wait for a decisive advantage to become available, like what happened with the knight.  I try to maintain a strong defense with locked positions.  My theory is that my opponent will eventually make a mistake.

1-f3 is a mistake, though.  In chess, playing actively in the opening is generally better, especially when it means not holding back your pieces from their best squares.

2-Just because you like it does not necessarily mean it is the best.  You're opponent probably could have gotten a big initiative because he had developed his pieces much quicker.

3-Is the knight and bishop combo so strong?  No.  It doesn't have a follow up.  If it doesn't have a follow up, it's usually not very strong.

4-You agree

5-You totally underestimate the value of a piece.  You're kingside would not have been wide open.  It would have had doubled pawns and an open file, but think about it.  How can he exploit it?  An inexploitable weakness is not a weakness at all.

6-Your pieces on the queenside are aiming toward the kingside, and are not doing as much for the queenside.

7-You agree

8-Ne2 is playable and better than Ne4

I think you're playing far to passively.  You see moves that are strong but you see that he has a move which looks imposing and you don't play that strong move.  Instead, you should look at those moves your opponent has and ask yourself if they really are so good or imposing as it appears.  Most of the time your answer will be no.  The thing about defense is not putting your pieces on passive squares.  It's about neutralizing your opponent's attack.  Aside from that, you need to play actively.  If you don't, how are you going to formulate any advantage of your own?

I will agree that f3 probably wasn't the best, but I wanted to hold my knights back for a defensive game.

Gotta agree with ZekesGhost, I think black is all over you until he hangs the knight.  The game turned in a heartbeat.   2. f3?     Nf3 is preferable.

7. Thanks for your compliment

8. I needed to unlock my queen and save the knight.

9. Don't ask me why, but I think he suffered a case of board blindness. (So he told me)

I do thank you for your comments, they encouraged me to reexamine my game.

1. I used f3 to limit my opponent's knight and set up a defensive position.

2. I was using my pawns to claim ground and set up defense, I like to use my knights behind my pawns.

3. I used a3 to block my opponent from bringing up his knight bishop combo.

4. Yeah, I got greedy with Qa4 I should have done another move.

5. There was more than only a slight compromise, My king's side would be wide open, not that my route went any better.

6. hxg5 would weaken me as most of my people are on the Queen's side.

I'll post the rest o fmy responses later, but even my responses are able to be commented on.

2.f3? Better is 2.c4.

4.c4 when you should be focused on your development.  4.Nc3 is preferable.

Not sure about 5.a3!?  Probably should check out a computer's advice on that one.

6.Qa4? is an error, forcing you to react after his quick 6. ...Bd7.  6.Qa4 is the kind of move you should intuitively feel is wrong.

10.Bxc4 is okay, but I would take the piece.  I mean, a piece is a big advantage!  Why give it away for only a slight positional compromise?

12.h5 Better and more aggressive is 12.hxg5 Bxg5 13.Bxh7.  You are attacking on the kingside, so there is no point to simply closing up that section of the board.

16.Bxc6 Good.  Take away one of his potentially active pieces and leave him with a bishop horribly placed at h6.

19.Ne4?! leaves you with a positional weakness after 19. ...Nxe4 20.Qxe4 Qxe4 21.fxe4, and in the endgame at that.

19. ...bxa3?? loses immediately.

Hope this helps, and if there are any mistakes in my analysis (though I have tried to keep them to a minimum), let me know and I'll change it as soon as I can.

2.f3 is not to recommend

If you had Black I think you had a pretty good game til you gave away that piece around move 20 - just a superficial initial readtion.
