From here: http://www.scharlesassociates.com/cases/psifraud-definefraud.htm We have this: "Fraud; the intentional use of deceit, a trick or some dishonest means to deprive another of his/her/its money, property or a legal right. A party who has lost something due to fraud is entitled to file a lawsuit for damages against the party acting fraudulently, and the damages may include punitive damages as a punishment or public example due to the malicious nature of the fraud. Quite often there are several persons involved in a scheme to commit fraud and each and all may be liable for the total damages. Inherent in fraud is an unjust advantage over another which injures that person or entity. It includes failing to point out a known mistake in a contract or other writing (such as a deed), or not revealing a fact which he/she has a duty to communicate, such as a survey which shows there are only 10 acres of land being purchased and not 20 as originally understood. Constructive fraud can be proved by a showing of breach of legal duty (like using the trust funds held for another in an investment in one's own business) without direct proof of fraud or fraudulent intent. Extrinsic fraud occurs when deceit is employed to keep someone from exercising a right, such as a fair trial, by hiding evidence or misleading the opposing party in a lawsuit. Since fraud is intended to employ dishonesty to deprive another of money, property or a right, it can also be a crime for which the fraudulent person(s) can be charged, tried and convicted. Borderline overreaching or taking advantage of another's naiveté involving smaller amounts is often overlooked by law enforcement, which suggests the victim seek a "civil remedy" (i.e., sue). However, increasingly fraud, which has victimized a large segment of the public (even in individually small amounts), has become the target of consumer fraud divisions in the offices of district attorneys and attorneys general." Fraud has not been committed, regardless of whether or not the binaries are close derivatives of each other. Notice these entries from the SSDF list: Rating + - Games Won Av.opp 11 Chess Tiger 15.0 256MB Athlon 1200 MHz 2719 23 -22 968 59% 2655 ... 13 Chess Tiger 14.0 CB 256MB Athlon 1200 2717 30 -30 557 61% 2638 The ratings are very close. I imagine that the evaluations will be similar. Does that somehow indicate fraud to you? And now look at this: 25 Gandalf 4.32h 256MB Athlon 1200 MHz 2658 31 -31 514 53% 2635 ... 27 Gandalf 5.0 256MB Athlon 1200 MHz 2649 45 -46 242 44% 2692 28 Gandalf 5.1 256MB Athlon 1200 MHz 2637 25 -25 758 55% 2604 Notice that newer versions may even be slightly weaker than older versions (though the difference is not statistically significant). Does that indicate fraud to you? All that it means to me is that it is very difficult to make a strong program stronger. I am sure that an author who makes a new release of his program imagines it to be better, and significantly so. The testing done by an author may not get the same results as the testing done by an independent organization. In my view, falsely accusing someone of fraud is as bad as committing fraud. Hinting that someone may have committed fraud is not as bad as that. But it still is not a very pleasant thing to do. IMO-YMMV.
