2 tries is not a real sample size but I can give you a few pointers to look at:
- Were there a few hands where you limp/called preflop, called flop and folded turn or river diminishing your stack considerably ?
- Did you chase a draw and missed?
- You could have just been unlucky like KK< AA or AA< KK aipf.
If you're unsure about a particular hand why not post the HH in the HA section ?
An added note:
Many of the members playing the CC freerolls
are experienced and rather good opponents BRed for more than just freerolls, no one said they're easy to take down.
