I'm in a slump.

I can't win...

I lost 15 games in a row. I couldn't win every game in the last tournament. My rank is continuing to fall.

The cause is to be killed my stones easily.

My 143rd KGS game (vs 3k, komi: 0.5, B) 

The important stones were killed in the upper side.

The other important stones were killed in the lower side.

I resigned at to be killed the big group.

All moves are here.

My 144th KGS game (vs 4k, komi: 6.5, B) 

The important stones were killed in the left side.

The big group was killed in the center.

I resigned at to be killed the big group in the lower right corner.

All moves are here.

My 145th KGS game (vs 5k, komi: 6.5, B) 

I lost by to be captured the important stones at the end game.

All moves are here.

I have to lean to be careful...
