It's no good for your development as a player to lose every game. And I personally don't feel there is any shame in handicaps, otherwise you might as well consider all of todays programs as handicapped compared to what we might have in 10 years. It's all semantics.

For improving at ANYTHING you have to have challenges that are difficult, but attainable. That's what the strength feature is for.

I do not believe in my life I have heard it put any better than that. And I like your "all-inclusive", not just pertaining to chess. Well said, Don.


Best,

its possible to play against full power. The lesson I always learn is how far I am to play decent chess.

Still, some few games are memorable battles (only for me) :wink:

I just finished a 12 game 5'+2" blitz ag. Komodo 4 32bit at full strength. It was a battle, but I won 5 - 4 with 3 drawn games. Tough chess- it wore me out. I had the pgns, but my dog ate them. :roll:

Sorry, if it touch you. It is only a BTW theme :lol: I understand that all the important things happen in the foreground. Sometimes it is good to hide a sensitive theme, 8-)

You need to trade in that 1975 8086 PC for a real computer :-)

Seriously, that is a great result, nicely done.

Actually i think EVERY engine including Komodo , fails miserably in this area. I mean the feedback we get from the engine is just a line and an evaluation.

Is that really all that could be extracted from a position? Are those the ONLY meaningful parameters that could help the human understand the position

NO. There are many many more things that could be returned in an "analysis mode" by an engine in order to "define" a % of certainty of how sure is the engine that this is the best move.

Which are these parameters. Well i guess this is a part of a research but
a) the numbers of fail highs and lows in the subbranch of the move
b) the percent of captures in the subtree
3) the percent of the evaluation that dynamic factors contribute in the position (in case the dynamic elements of the position wear off...)
4) the probability those dynamic factors wear off (as a percent of the subtree analysed , meaning that if in the subtree of MoveA 1% keeps the dynamic factors and 99% loses those and we and up in a position where static evaluation is important, then its possible that the opponent will somehow find a way to fight the opponents initiative....etc

Anyway, there are many ways to get feedback, but every chess engine author, just chooses the usual "eval + line" which is definitely not ok for human analysis
