I recently read a bit about Chess Eye. It is essentially software to help with chess visualization even when there is no board. It seems very useful for blindfold players. However, would this software benefit an OTB player over 1700?
"There are also exercises to develop calculation skills: playing through games blindfold (an idea borrowed from Alexander Beliavsky), and the use of 'stepping-stone diagrams' (a Tisdall original - while trying to visualise a position some moves hence, a player fixes a half-way position in the mind's eye, then, when this is secure, continues calculating)."
I guess at the end of it day its helping you see deeper varitions more clearly, less chance of missing something.
