Hi all,hi Peter I can't agree with you, of course if you want to become stronger you have to read in your head and make a lot of life and death problems. I am 3k and i never used the editing possibility to try out sequences of moves, when playing a game, because i don't find it useful for me ; but what about my opponent using edition? I don't think he's cheating he just help me being stronger ! Why? because he makes the best moves a player of HIS LEVEL can do the edition don't improve his strength. My ask is for evaluating position. How to learn it ,there is no books like= TESUJI,JOSEKI,FUSEKI,also MIDDLE GAME and LIFE AND DEATH. I find in gGo editing a good way to do so. But, Peter, you made this nice gGo program and decide this feature have to be removed; nevertheless i continue to use gGo. Greetings G=E9rard
