defending the queen from infiltrating...teach me the lessons from my loss here.

when i lose i want to learn from it. here is a loss and i want to make sure i learn everything i can from it and i know there are many stronger players here that can break it down for me so i'm sitting here ready to learn the lessons. go! and thanks.

Your second move (2. ... d5) lost a lot of time by getting your Knight kicked around, ending up on a rather poor square.

5. ... Bg4 was OK, because it pressures the White Knight that defends the d4-Pawn. But you should have gone ahead to increase the pressure on that Pawn, rather than just developing pieces randomly.

Ignoring his 12. Rfd1 was probably the game-loser, though. That's one problem with putting your dark-squared Bishop on e7. It's a nice square for the Bishop, but it would have been a good square for your Queen in reply to 12. Rfd1, instead.

8. ... Bb4 pins nothing. Save tempo by Be7 immediately. It's okay.

12. ... Qc8 get the hell out of that pin, especially when it's directly behind a pawn lever.

Nhm... I'm not really high rated, but I suppose experience killed you, I just play for fun so I'm not really sure whether you'd want to hear or not, still I'll give it a shot

Move 2 : I don't really like this move, if cxd5 either you take it with your Knight, or your Queen. In any case, your losing Tempo. I'd have played something like ...c5 3 d5 d6

Move 3 : By taking with the Knight your removing an Important defender if you plan on castling King-Side... Just guessing it'd be exploited was he tactically sharper

Move 6 : e6? Nhm.. not really sure about it...Maybe Kb8-d6 was better followed by e4

Move 7: To answer your question, probably not, if Bb5 Qd7, Kc3 Preparing to push E5, Cannot really find a way to defend the knight... But generally I'd play Be7 to Castle/ Push c pawn

Move 8: The point of putting the Bishop/Knight in this position is to either create weaknesses or Pin Queen/King, and this is doing none.

Move 12: as I said, Experience, Putting the Rook, in the same Collum ( how do i spell it) as the Queen is a common move, maybe dangerous if your not aware of it. Thus you have yet to complete development, your rooks are NOT connected. In this position I'd have pushed c pawn.

Move 14: Strange comment.. I don't see what was achieved, the Queen's still pinned. At this point I'd have resigned. Not only because of the piece's loss but because of the terrible Knight position.

 Well that's just my point of view, I'm a rather novice so I might be wrong at some points, but.. I just wanted to help >.> Peace.

thanks for the comments... at the ending did i have a way to set up a good defense to prevent the queen from getting into my back rank or was i right that it was inevitable?

It was inevitable. Out of all the pieces, never give up your queen unless your opponent is going to pay heavy for it - like both rooks and a minor piece or three minors and a rook. The queen has forking abilities that the other pieces do not.

right but i was forced to give the lady up or else just go down a piece for nothing. i figured it was either give the lady up for a knight and rook or resign so i decided to play on and give the lady up. the lessons so far are keep aware what ideas your opponent is trying to accomplish, always double check for pins and don't let your knight get kicked around early and let them develop their pawns in the center.

Grab a piece of the center and hold onto it for dear life. It is your shield. It keeps the enemy at bay a good distace from your king. Comtrol the center and you can reach all 4 corners of the board efficiently in the fewest of moves.

Prolly not, Advantages specially Piece Advantage becomes more and more clear as you trade pieces... Unless your oponent make a mistake...I think it's impossible...

Not talking about after losing a piece. Just basic strategy.

@cornbeefhashvili:

figured, was just answering his previous question.

However I do have my doubts about talking about center control, It doesn't help to have center control and don't know what to do with it....

First, I probably would recommend a more "standard" opening than the mexican defence. Something that gives you pawns in the center as well. Allowing your opponent to have a pawn center can be playable if you know what you are doing: but if you mess up after he has got the pawn center you risk getting crushed.

7. ... N8d7 -- my gut feeling move would be c5 there, so I could play Nc6 next move. He can not play past (8. d5 exd5 9. exd5 Qxd5 loses a pawn for white), so his options are to take (8. dxc5 Bxc5) develops your bishop, and ignoring allows you to take and give him a isolated pawn. All responses to the pawn situation in the center improves black's position. When your opponent has a pawn center, try to find ways to attack and break it.

12. ... a6 is terrible. Not only in light of what happened, but my gut feeling move is to play cxd5 -- open up the c-file so you can put a rook there. It is often good to have a rook on the same file as opponent's queen.

Stopped looking there, the game is lost after that. 

Thanks for comments!

Certainly not.

It depends on the positions of course, but generally speaking the queen is worth about two rooks, or three minors, or even a rook, a minor and a pawn.

The endgames R+3min. vs queen or 2R+1min vs. queen is actually winning in general (ie when the player with multiple pieces is not under check or really specific positions). (This is of course no proof that the multiple pieces are better in middlegame situations, since two knights are certainly better than two pawns in the middlegame, yet two knights cannot mate)

Take nine and a half as the value for a queen.

For 10 moves you developed your pieces. The remaining tasks were to find a safe place for your queen off the back rank (to unite the rooks) and to get the rooks onto good squares - d8 and c8 in particular (the half open files).

You did nothing to pursue those tasks. In contrast your opponent did.

Two of the opening principles are to move pieces not pawns and not to launch an attack before development is complete.

I didn't understand why Jo resigned, he had to explain it to me! I simply blundered the pawn at move 31, and 32. Qd3 only tries to push the passed pawn. If not the mistake 12. ...a6, the game would be very different. Jo's comments are making me feel this win could be the only one... :) Thanks to all anyway, I'm learning a lot too. But sure is the pawn unstoppable?
