Hi,
I apologize... I have to post this question again in a dedicated thread, as the device triggers many comments and my question looks now to be buried alive.

So let me repeat myself: a question to TT Proelium owners (maybe answered by TCAII owners too, as both chess computers obviously share a lot): the SCORE feature isn't totally clear to me, from just reading the pdf manual.

I think I understand you can get 3 values:

- the score displayed at the end of the WHY? process in tutor mode, once the tutor announced a doubtful move. I trust it should be the resulting score IF you play your intended (presumably bad) move. Score of your potential position, so. This one is rather crystal clear.

- the score displayed if you press the relevant SCORE key while the computer displays its move. I guess the move is still to be executed by the player on behalf of the computer; LEDs (on the Proelium) are still flashing to show the piece move. My best guess is this score is the one computed in the process to choose the engine's displayed move, and according to the manual, a vertical double arrow is as well displayed.

- the score displayed once you moved the computer piece, if you press the SCORE key afterwards. I guess the computer's move is no more on display, at this step. This score is sayed by the manual to be the position evaluation. I wonder if this is just the above, negated, computer score , or is it a new run of an evaluation; in other words does the computer need some delay to compute this eval or does it sometimes show a different absolute value, compared to the above?

I plan to run the Khmelnitsky test once I can get my hands on it, using the most relevant score is key.
Thanks for feedback!
MfG,
Eric
