Shredder makes a beautiful diagram over the approximate strenght of each player's position for each move in a game. Great for quick analysis to find any turning points. I might consider buying it, but perhaps there are free programs that does the same? I didn't get Arena to do it... what else would you recommend?

wait 1 week... :D
