Hi Chris, Thanks for your response.
Don has stated a couple of times that option (A) worked better for him. I chose option (B) without testing option (A) because I did not want to have to decide how many seconds to use to guess the opponent move before starting to think about my next move.
There is no need to spend any extra time if you choose option A. You can just take the guess as the 2nd move from the principal variation when you generate your original move.
