Tips for my the 1st tournament

In any case, attitude is important. You want to stay motivated and positive. For some that means crush, for others it means "these are just practice games."

I really liked this article:

I think parents are teaching kids some bad life lessons.  I see kids that slam the pieces down, say "Check!" loudly, they dont shake hands, they arent taught to win, draw, and lose with grace.  Obviously this is a small percentage, and i feel bad for these kids.  They grow up with the nike mentality that winning is all there is.

OK, here is my the first lost game. The second one tomorrow.

A lot of Masters lose when they start out. Just learn from your loss. Get a strong player to help you analyze. That guy is rated pretty high.

Don't try to be perfect.  Check for tactics, find a reasonable move and make it.  Save your time for the critical moves; that's when to really apply yourself.  If you try to make every move perfect, fatigue will kill you.

I think just sticking to the general rules for the opening is really all you need at this point, these rules will give you the flexibility to play moves you like and also keep things solid and on track.  Mind you, there always the occasional exception or trap that occurs, but that's where getting nailed by them in games makes you avoid them in the future, for example, the e4, e5 pawn fork that happened, commit that to memory and for the next while, make it a point to consider if your opponent is threatening it.

as for the opening principles as I recall them

- get a foothold in the center with a pawn and try to hold it there, even better if you can get two there side by side.

- get you king to safety, which you did.  Avoid moving those 3 pawns in front of your castled king as doing so might create some weaknesses that are hard to repair later, like a leaky roof.

- usually preferable to develop the knights before the bishops, the natual developing squares are almost good homes and support the center. The bishops need a bit more thinking about where you want to put them

- try to avoid moving the same piece multiple times.  In this case, playing Be7 and then Bd6 loses a move, and to a lesser extent, Rf8 to e8.  Perhaps you just changed plans to try to get ..e5 in, but the loss in time makes it easier for your opponent to start some unpleasant attacking ideas.

I would also add: don't block your c-pawn (e.g. with ...Nc6) in a Queen's pawn game unless you have a very good reason (Or if you're playing something like the Chigorin defence). The reason is the c5 pawn break is a very important theme in these types of positions, as well as the pawn on c6 is useful to reinforce the d5 square :)

Ah, I see your online rating is actually pretty high for a novice OTB, not very far from mine, and I've been playing for some 30 years (I can't seem to get much past 2100 OTB) you clearly have a good foundation from what I see, you can probably ignore my earlier post.

There are a couple of things I can think of, that if can be improved upon might help.

- Fast time controls, I'm know as I'm bad at this.  I'm not sure how to fix this myself, but I can relate, I play relatively better the longer the time control.  I try to approach every game and use all of the time given to me, you might be feeling pressured to play quickly, try to avoid that.  I think it's better to spend all your the time and lose instead of playing too quickly and losing by making silly blunders.

- Online vs. OTB, there are a few factors here, dealing with the clock, recording moves, opponent's annoying nose whistles, etc.  This really only gets better by playing in more events.  Maybe try to recruit a local player to play some slow games against..I found playing games lika that in a noisy atmosphere like a cafe helps :)

Okay, I'm going to give some advices which are tried and true and nothing too original:

1. Pick classical openings.  The reason is openings such as the Najdorf and King's Indian are played by higher players as a certain level of complexity is needed to generate winning chances, as simpler openings will lead to equality much faster even without theory knowledge by such players. You don't need to memorize 20 moves of a poisoned pawn variation when gaps in the opponent's understanding can be exploited much simpler with 1...e5 systems.
2. The queen is the most powerful piece and queen endings have a big danger of perpetual check (though two rooks and queen vs. two rooks and queen endings are quite fun admittedly), so try getting them off the board early unless doing so gives them a positional edge or even worse.  The Berlin Defense as black and exchange Ruy Lopez as white are good openings to take up.
3. Don't concede the center at all!  Keep it overprotected to maximize your pieces' flexibility. 
4. Study rook endings, especially the Lucena position, Philidor, and short side defense.
5. Study some annotated games of Wilhelm Steinitz. 
6. To avoid early mate get queens off the board so you could get closer to an endgame where technique plays a bigger role than careless mistakes, though big problems can still arise in queenless middlegames so be careful. 
7. Keep in mind positional imbalances so you can know what to revolve a plan around then formulate candidate moves within the context of this plan.  If the opponent has a potentially dangerous plan think about prophylaxis. 

Many many thanks to all again. Also to Airut for commentation of my game. It´s megapocket of advices, I have to read them again and again to understand all.

Meanwhile, my the second lost game:

The way to avoid early mate is not to get the queens of the board unless doing so is objectively good. Also, you usually should trade queens when you are up material. Doing this will prevent you from getting practice with sharp middlegames. Note that your opponent also has great chances to mess up in these middlegames. So, playing them well will give you a big edge.

The way to avoid early mate or other blunders is to practice tactics and blunder-checking and playing more long games (and analyzing them). This way, you will also become better at punishing the opponent's blunders.

What a spammer! Is this the 10th thread you posted that in?
