inconsistant but can beat higher rated opponents?

I play mostly standard length games because that is more like real chess, instead of blundering in the blitz and bullet games.

My standard rating fluctuates in the low to mid 1500's.  My goal is to get to 1700.  I have the ability to beat higher rated opponents in the 1600 and sometimes even the 1700 rating.  But sometimes I just play bad chess, hence the 1500ish rating.

If someone has a time to go through my games and give me a few tips that would be great.  Ideas on what I'm not doing right.

And I like to play the Sicilian and French as black but i haven't found a favorite white opening, although latley I've been experimenting with the Vienna game.  Knowing that i like the Sicilian and French as black, what would be White openings that get to those interesting positions.

Last if someone is around 1500 and has a goal of increasing their rating to 1700 add me as a friend.

Enjoy your chess and have fun!!''

I went through your last 3 lost games.

Your play is certainly OK, and in fact it's not too bad for a 1500 rapid rated player.

The biggest issue you have is that you make tactical blunders in your games, which causes you to lose, and I mean unprovoked tactical mistakes that don't come up because you're defending from a massive attack, but because you just didn't see something rather simple, and so you drop a piece/pawn.

Before you make your moves, I'm sure you know that you should consider the opponent's replies, especially the opponent's forcing replies - checks captures and threats. These are the moves that your opponent can use to defeat you tactically.

Your next big issue is your time management. In the second to last game you lost, you had 15:00 at the beginning of the game, and when you resigned you have 14:57. That just isn't right. In the last game you lost, you still had most of your time left.

You need to use your time more wisely, to check your moves more carefully for safety, and opponents' responses. That's what the time is there for - for you to think and make sure your moves are OK.

You need to practice this, but this is literally all you have to get good at (checking opponent's responses to avoid *simple* tactical mistakes in relatively simple positions) to get to 1600,1700+, since your play otherwise isn't too bad, and in fact is above 1500 level, I'd say (positional play, for instance - you have a solid grasp of basic positional knowledge, for the most part).

As for openings, the openings you play right now are fine, and I wouldn't care too much about changing them for the time being, unless you really don't like one of them. Avoiding losing pieces/pawns is what I'd care most about.
