How to move (drag) chess pieces
1) Select a chess piece by clicking on it with the left mouse button.
 2) While holding the mouse button down, move the selected chess piece to the desired position.
3) When the chess piece reaches the desired position, lift the mouse button.
    
How to search the database for a position
Setup the desired position on the board by moving the chess pieces. Make sure that on the right hand side you see the 'Search Games' tab is selected. If you want to see if your position occurred in any of the latest chess games played between 1991 and today, you may press the search button now.  You may also want to look for your position in ChessLab's historical archive (1485-1990).  To do that, select a different date range: "Historical archive (1485-1990)" and press the search button. Once the games are found, highlight the desired game and press the load game button on the right-hand side.  The game will be loaded into the ChessLab board and you will be able to use the VCR-like buttons on the left-hand side to play out the game.
     
How to search the database for a known chess player
If you want to find all of the chess games played by a known chessplayer, select the initial position on the ChessLab board.  You can do it by pressing the Initial Position button.  If you want to find all the games where that chess player played the White pieces, fill out only the White Player last name on the right-hand side.  Otherwise, fill out the last name for the Black Player .  If you are unsure of the spelling, you can just fill out the name partially: for Alekhine, you can just specify Alek.  Also, select one of the two date ranges: Latest games (1991-present) is the default selection.   For example, if you want to find all the games where Alekhine played White, please select Historical archive (1485-1990) and press the search button.

 

How to analyse the position
First, select a position for analysis by moving chess pieces on the ChessLab board.  After that, select the Analyse tab on the right-hand side.  Press the analyse button.  Once the analysis process completes, the suggested move and, optionally, variations will appear.  You can play the suggested move by using the Play it button.  To play variations, use the VCR-like buttons next to every row of a variation.
