Trying to plug some holes.

[guild12]

Hi all,
I'm trying to improve my NL Hold'em tournament strategy/game and I'm not sure where to start. In small multitable (18 and 27 player from $5-$15) sit and go's I have an ITM% of about 30 and in large tournaments I average finishing in the top 25-30% only hitting money once.

It seems that I hit a big hand and go above average for a while. Then I slowly fall in ranks and wind up in a position where I'm low stacked and have to go all in on less than premium hands. Is this an indication that I'm playing to tight?...Or that I'm playing too many hands. I'm leaning torwards not playing enough hands...but I'm not sure how to tell.

Also what is considered average and above average ITM% for serious players (for lack of a better term).

Any thoughts? Let me know if more info is needed. This is the first time I'm posting here.

Thanks
