Why did I remove the alias page I made recently? Because an internet search of yokozuke (in katakana) did not turn up any go pages, while a search of yokotsuke did. Truth to say, I would have said, yokozuke, and was surprised by seeing yokotsuke. Now, it may be that either is correct, as with nakade and nakate, but I am not sure that yokozuke is correct as a go term. If you are sure, please restore the alias.
