Tool for analysis of end games.

Hi,

I am looking for a tool (prefebrally free :) ) that can aid me in end game analysis. These are the features I am looking for:

1. It should allow me to setup a board/position easliy.

2. After I make some moves for white / black, I should be able to play / unplay the moves using hotkeys.

The tool need not have AI - I need it just for analysis. There are tons of free tools available at chess.com itself. If anyone knows a tool that I can use for the above mentioned points, please let me know the name.

Thanks in advance.

Chessbase light does all that and more and has a free engine to boot. you can pick up the free version from this url >>>>>>>>>>>>>>>>>>>>>>http://www.chessbase.com/download/cblight/index.asp
