If you pickup Chessman’s piece on the board is it considered to move or can you put back down and move another chessman?
Yes, if you touch a piece you must move it if it is possible to make a legal move with that piece. You are not allowed to move another piece.
This is called the touch-move rule. “If a player intentionally touches a piece on the board when it is his turn to move, then he or she must move or capture that piece if it is legal to do so. This is a rule of chess that is enforced in all games played in over-the-board competitions. The player claiming a touch-move violation must do so before making a move.” Wikipedia
If you hold a piece in your hand you can place it wherever you like. But as soon as you have executed the move and let go of a piece it is against the rules to pickup the piece again and move it somewhere else.
I hope this helps.
