If you want to make better analysis of a position, in less time, I think to be better use the team man+machine, mainly with chessbase engines. What I understand for man+machine: 1. Put the position. 2. Choose Infinite analyses, and choose the number of moves that you want to see, pressing the bottons "+" or "-". This bottons are finded above the counter nodes.In the majority of the cases I choose N=4. 3. Leaves the program to analyze the position for approximately 3 min and choose one move, established in your experience,or one that is between the N moves, and study the main variants, always forcing the program to play a move. 4. Choose another move from the inicial position and make another study, and thus for ahead, until giving for satisfied with the examination of the position. The great advantage of this method is that when you force the program to make a move, you gained 1 ply, what it is not little thing in time. In an analysis of that type, you arrives to gain between 5 and 15 ply(!), depending on the patience that you have to make the analyses. The disadvantage is that you can lose a more advantageous variant if leave the program to analyze the position for some hours. My experience with this type of analysis is that the advantages compensate the disadvantages, without doubt. I think that GMs and his team, use this method to found theoretical novelties.
