Hey. 
If you haven’t created a child theme, start with doing that. 
Create the file bbpress.php in your child theme.
Copy the content of your page.php file into this new file.
Remove the line 
<?php get_sidebar(); ?>
You’ve removed the sidebar 🙂
Now you only need to change / add some classes / ID’s and adjust your CSS file to give the forum a 100% width.
Keep me updated 🙂
		
	 
	
	
	
 
		
			
	
	
		
		To me it seems it all works perfectly. Just add
.two_third { width: 100%; } 
to your .css file
