Personally, I think that, while playing a game, evaluating past positions with a computer gives you a huge advantage. Being suggested a move always means asking "why", and often leads to a change of strategic objectives that often have impact in the endgame, much later. Often Zebra suggests a certain move several times during a game played on the board, and if players knew that would certainly have changed their point of view. Even looking only at past opponent's moves, IMHO, gives a lot of hints on how to play. When playing on IYT I discussed a lot if it can be considered "cheating" just evaluating with a -passive- board instead of pure brain thinking on the position!
(скрий) Ако чукнете на нечие име и после на "Завършени игри", ще видите списък на игрите, които са завършени. После чукнете на името на играта за да получите кратко описание на тези игри, после чукнете отново на името на играта и ще имате игра, която да разгледате и да анализирате.
