This is my first post - I hope I've put it in the right forum.

I want to post a strategy I have used lately to help me steal blinds late in a 800-chip STT SnG. I have employed it when I haven't won any major pots, so I am a short stack with approx. 5-6 players left in level 4 or above. I tighten my push range from what would normally be a clear shorty push, and I only push pairs or AT+. I do not push A9 or below. I have found that even though I may be missing some stealing opportunites while doing so (and obviously decreasing my stack), when I do push I get called - people must think I'm now more desperate than ever since my stack has decreased some. When I get called, I'm usually ahead and double up. I still don't have a huge stack, and am probably still a short stack. But now when I make a steal attempt it is more respected and ususally successful.

Essentially, I guess I am tightening up waiting for a premium hand while other short stacks are loosening. I tolerate a decrease from say, 900 to 550 duing levels 4 and 5. But my double to 1100-ish and a few steals due to my tight image puts me back around 1700 - essentally where I would've been with a double up earlier. Also, it is usually another short stack calling me with thier wider range, so a player other than me is eliminated or crippled.

Thoughts? Have I been lucky or can this method yield sustained success?
