My first NL session - 2hands

[AZplaya]

Welcome to NL, a world where double digit PTBB/100 is possible. Here is my advice.

Hand 1 - raising from the CO w/ AJo is fine, but raise bigger. Raise to $3.50 - $4.00. That said, I usually fold AJo to a UTG raise.
Flop - GF

Hand 2: Again raise more. You want to make it 4xBB + 1BB per limper, so raise to $1.25. On the flop, I would raise to about $6, fold to a push. You have the NFD with KK, so even if SB has the flush, (s)he will prob give a free river if you decide to take it.

GL, and post lots of hands, this is a complex yet highly profitable game.
