Old v. New Chess.com and conditional moves

I just clicked some button to get into the old version of chess.com to try to make a conditional move because the new version would not accept a conditional move and now the old version won't accept the conditional move and I cannot see how to get back to the new version. Please help. How do I 1. make a conditional move in the new version of chess.com, and 2. travel back and forth between the new and the old version of chess.com.

OK, I just figured out conditional moves, but I had to completely log out and back in to get to the new version. Is there a simpler way to move between the two versions?

The conditional moves in v3 can be found when it your opponent's move and the button looks like a forking arrow; second button.

To get back to v3, there is a link at the bottom of most pages that says Try the new Chess.com that links to www.chess.com/switch

In v3, there is a menu item to switch back.

OK - ignore both my previous posts - the quick way to get back to the new chess.com is at the bottom of the screen with "Try the new chess.com".

Thanks, Martin - I was typing my last post just as you replied!
