I have 4 days in a roll playing for cash my experience is the next
1.- the cash game with 80c are to damn hard (Jaja for me are, ok)
2.- if you limp you always lost money
3.- the table with 10 dlls are calm, my hypothesis is "the pressure to lose money it's more" so the key how many control of you do you have
4.- be tight and aggressive
5.- enjoy
