Glad you like it. As I recall it wasn't the forced moves that were causing the trouble, they are always going to be a tiny percentage. It is those situations where the best move is clearly best, the sort of move that an engine will find and so will a good human, that worried me. I wasn't worried because including them might indicate engine use, that situation ...[text shortened]... average number of "best" moves is so high and could be used to justify high match up rates.

Apart from intresting and what you can make of it for the engine usage issue.What I want to know: did it help your chess any?
Originally posted by no1marauderI don't want to jinx you, but I find when I study anything that deeply impacts my chess in some way, or if I take lessons, I play worse in the short time period after. I think this was discussed in another thread, and is probably quite common. Read the book, but then give yourself enough time after to flush everything out until you're just playing like yourself again.

Originally posted by no1marauderIt would justify the idea that someone routinely cranking out a 20-50 move forced draw or win is possibly using a chess engine.
Musing on these figures they certainly show that forced moves are relatively rare. What light does this info throw on previous threads regarding the differences between the play of an engine and that of strong human players?
Originally posted by no1marauderVery unlikely.

How likely is that?
Originally posted by no1marauderInteresting stats.
The percentages of each type of move were (combining the two studies :
Book - 29%
Forced - 6%
Best - 30%
Discretionary - 35%
Originally posted by Dragon Firethat's true, and I think it's a very good idea, but for that, we need a sample of real and strong correspondence chess players (a collection of games) from this site. (to determine those realistic percentages.)
[b]Of course I have used guesstimates as my percentages just to illustrate the idea but if realistic percentages can be determined then this becomes a perfectly reasonable way to conclude someone is not real[/b]
Originally posted by bassoBobby wasn't talking about CC.In OTB if you found a good move play it or the 17th piece will kill you.
I am intrigued by this quote of Bobby Fischer's: "Don't worry about finding the best move. Just try to find a good move."
Some time ago I heard contrary advice, which was to, after finding a good move, try to find a better one. You can imagine what taking this maxim to heart did to my playing time here at RHP with it's unlimited playing time (virtually unl ...[text shortened]... ng off and just looking for a good move . . . but I must play the [b]best game I can![/b]
