Your "question" is not very clear but I do see possible problems
dbCommand = new SqlCommand("PoolGames'" + PoolGame + "'", dbConnection);
Assuming from this that you are attempting to call a stored procedure you must tell the SqlCommand object that is your intention. By default it will assume command text.
dbCommand.CommandType = CommandType.StoredProcedure;
Also, the name you are passing to the constructor will be generated as this "PoolGames'PoolGame'" when I believe you want is this "PoolGamesPoolGame". Notice no single quote.
