I've noticed you've dropped from the higher buy-ins to the 25 and 10-cent tourneys. That may be too low. IMO they're only slightly better than playing freerolls
I rarely play ring games, so I can't offer any advice there.
Looking at your OPR stats, I'd say you're too tight. Your early-middle and middle finishes are way out of line from just the average.
Just a couple of questions:
***Do you find yourself pretty short on chips by the first break?
***Do you findyourself allin pre-flop right around the break or in the second hour most of the time?
If that's the case, then you're probably playing too tight.
I'd recommend the FTP Tournament Strategy book and google "Bond18" and read his 18 part series on "Things it took me a while to learn."
