I can't get premium so I only have one game review per day so how can I analyze my mistakes/blunders for free?
As almost everyone of advanced rating will tell you, there's little value in getting a computer to run an analysis for you until you have analyzed the game yourself.
You could do your own analysis and post your questions here.
