Computer Analysis Words Defination

Can someone plz explain the difference between Inaccuracies,Mistakes n Blunders as used in our Games Computer Analysis .. Tnx so much !!!

All about the severity of the errors you are making.

A blunder is the worst type, something that can swing a won game to a draw or a draw into a complete loss that's very difficult to stop now.

A mistake is costly ... and you're royally screwed if you made it against a strong player who can and will punish you for it totally, but in general, there's still a lot of chess left and I wouldn't really say it's time to resign.

An inaccuracy is not so much a mistake as it is an inferior move ... there was definitely a better alternative in the position.

Really strong players seldom make Blunders and mistakes ... just a few inaccuracies, if any.

Ok .. Tnk u very much ,Shivasky !

What numerical value of change does the computer need for a blunder/mistake/inaccuracy?

as some people have stated, it basically measures the magnitude of the impact of the error. humans would sometimes use these terms "inaccuracy," "mistake," and "blunder," to indicate how "easy" or "hard" it was to make that mistake. but since the computer analysis is done by a computer, it measures based on change in evaluation.

And the numbers used are roughly:

0.3 -> inaccuracy
0.9 -> mistake
2 -> blunder

Yeah,I agree .. the Computer cannot tell when we r act making a well planned sacrifice ; hence our so called analysed mistakes/inaccuracies could act lead to a Win finally .

..but I guess it muz hv its own 'computer based-logical' reasons for analysing a certain move as an inaccuracy/mistake { which may seem illogical to us,at times } , tho like u said,the human mind seems to be far more complex than /superior to that of the computer's ??? .. hehe

Tnx so much .. paul211 .

Btw,If anyone knows the answer to Chessy4000's question above,can u kindly respond .. tnx again.

Ok, tnx ,IM dpruess.

welcome :)

 intresting... i should remember that :D

Yeah, 2+ is blunder and if I play a move +16 instead of +20 it keeps telling that I've blundered, I'm terrible etc. :D
