as I already suggested it would be useful to be able to make the engine show you forced lines, but an even more important and easier idea is following:

right now I am analysing a difficult ending from one of my corr. games. the position is very static and the only winning attempt includes a kingwalk over the whole board. if white's king reaches a certain square black is dead lost, but rybka needs even in this position quite some time to smell the danger.   black has to avoid this idea, but it's very timeconsuming to analyse it with rybka (or other engines), since this lost position can be reached through innoumerous lines and so using "preserve analysis" to teach rybka the problems doesn't have the desired effect. after some work I understand this position better and now could define several positions as lost. so it should be easy to tell rybka positions x,y,z are lost and a,b,c are drawn and it overwrites her own eval in the hash with your manual eval. so rybka would try to avoid these positions and probably I could solve the problem within minutes.

idea in short: be able to overrule rybkas eval of a certain position and make her use the new eval in the search.

I really think this feature would be incredibly useful!

Good idea in my opinion.  I like it. By doing this, it could sometimes be used simultaneously with an idea I had of telling the program to manually analyze pre-selected moves in the game.  Wow, I really like it.  I hope Vas feels the same way.

I would like to have the evaluation of the played and proposed move in the analysis feature i.e compare analysis or full analysis.

AFAIK the UCI protocol doesn't allow commands for the engine like:
"Analyze this position, give me the best move and also the evaluation of Nf3"

UCI protocol is not the must which shall limit Rybka GUI.
The Rebel GUI was allowing that and 2 additional lines.

UCI protocol is what limits Rybka so far. So to implements such features we need cooperation with Vas.

I don't get what you propose. you want to have displayed the move rybka considers best and the move, which was actually played in the game? so this would only be for the post mortem analysis of a agme, but why is this useful? rybka displays anyway the moves she considers best and by going one move further you get rybkas eval after the actually played move anyway.

in my opinion this feature would not be very useful.

Perhaps it would not be very useful, but it would save one click!

for saving one clicks you would have to turn this "feature" on before analysis.
this is just a  gimmick - no feature for real analysis. if you go through the game you always get the eval displayed and automatically see where rybka disagrees with the course of the game. lousy idea.

rivaldo, don't discourage people like that :) I can imagine someone who does nothing except post-mortem analysis and is dying for this feature, so it's worth mentioning here.

I don't think it's worth implementing though because it will be too hard and it is not really a must.
Parent - By Hetman (*****) Date 2007-11-14 18:18
I am not 'dying' ;-) for that but it will be very convenient for me. I am using mostly post mortem analysis for OTB games.
It shall be not too difficult to implement. Program is analysing some variations in the position, it is only a need to write the evaluations to the file.
