Hello Martin,

I would like to distinguish severely between

* those players who only use the (single) best proposal of their program

and

* those who let run the program in 2-best or 3-best mode  -  finally selecting
from the two or three candidate moves shown.

Such a multiple-choice mode can lead to a trememdous increase in
playing strength. Years ago I made such multiple choice experiments
in "over the board" chess, calling the system "Double-Fritz plus Boss":
Fritz4 computed its two best candidate moves and me (=the human boss)
always had the final choice amongst them. In two events in 1996 (the seven
round open tournament in Apolda, and a 4.5:3.5-win in an 8-games match
against GM Gennadi Timoscenko) "Double-Fritz plus Boss" scored around 200
rating points better than Fritz4's own (SSDF) rating.

Using computer proposals in multiple choice mode can be
a trememdous help (not only in chess).
