Here is my general freeroll strategy. First level of the tournament I'll play almost anything if only the cost of the BB. At the start I never slow play good starting hands, jj,qq,kk,aa, I always raise big. Alot of freerollers will play anything on any raise so no sense in slow playing.
After the first few rounds I tighten up play. Playing more premium hands, I'll play a little loose if on the button. By now most the alliner's should be gone and play usually starts to tighten up all around.
Through the end I keep tightening up, hope to take down a few big pots and win the tourney :D
See you at the tables.
