Researching Players

What are some ways to research online players?

I am aware of sharkscope, are there any more/better websites like this for gauging another player's ability?


I know you can get around player search being turned off by tagging a player and looking around active tournaments / tables. Are there any other ways to do homework on your relatively unknown opponents?

There are programs for the collection of statistics,and tells the players watching the game and remember.I don't use any...
