Example: The coach thinks you have blundered. Score in position after optimal move is +1.5. Score after your move is -1. Would you like to take your move back?

or the above message is stored in the PGN window as a comment. In essence, the game would be blunderchecked live.
I think after you get the coach's warning that you've just played a bad move it would be better to simply append the coach message to the SCID or PGN file with the two numerical evaluations of the position: after the best move and after the move it was actually played.

Revealing the exact numerical evaluation of the position while the game is still in progress is like giving away too much, don't you think? Or, it could be configurable, that is, the user could choose whether he wants to see the numerical evaluation in the popup message or not.

Rather than simply mentioning that the coach thinks that you have blundered, it might be better to have an option (before the game start) which indicates the thresholds to look for. Then depending on the option the user selects, either the wrong move and the right move along with the difference in scores can be annotated on the PGN screen or simply be passed to the user.

For now I prefered to make the user interface as simple as possible. Depending on the score drops, the player will get the warnings :
# minimal value for ?!
0.5 -> dubious move
# minimal value for ?
1.5 -> weak move
# minimal value for ??
3.0 -> Bad move

Those values are the same than in "tactical game" and are statically defined for now, but of course the meaning for dubious/weak/bad moves may differ between engines and people. But I prefer to get a message like "you played a dubious move, would you like to take back ?" than a message with numerical values, which I find less human-friendly.

As this is supposed to be a "serious game" I prefer not to write down in PGN any kind of analysis as the engine may itself be wrong (usually I give Toga only a few seconds ... and it easily wins). Annotation is a post-mortem process where the engine should analyse at full strength (and not with a limited number of nodes or fixed depth). So during this phase I prefer not to write any analysis, but the user, if taking back a move, will have the opportunity to enter a new variation, and he will see where there were a potential problem.

As I already wrote, I prefer human friendly messages instead of numerical scores (which meaning differ a lot between engines : see Rybka and Toga for example).
