I can add that I am talking about the previous tournament when I became the
Israeli champion in correspondence chess.

In that tournament I played 8 games and it was mostly by mail(I played 2 games
by emails and 6 games by mail).

Now I am going to play 10 games by email and I think that I am going to use
relatively less time per opponent but I still expect to give programs to analyze
some hours per move except some obvious move in the opening or forced moves.

Note that even in the opening after some moves I am not going to trust blindly
the opening book.

I will probably give in most cases only one engine to analyze the root position
for some hours and I may do more analysis of other lines dependent on the
position.
