A quote from Rajlich: > Yes, the publication of Fruit 2.1 was huge. Look at how many engines took a massive jump in its wake: Rybka, HIARCS, Fritz, Zappa, Spike, List, and so on. I went through the Fruit 2.1 source code forwards and backwards and took many things. It's not as if he never admitted to studying Fruit. Also, most of the confusion is there because Rajlich didn't have a repo until Rybka 4, so when the reverse engineered his code they formatted it the same way as Fruit, making it look very similar. If a judge missed the bit saying that the Rybka code is "functionally equivalent code", not the actual code, they might be fooled into thinking the orignal codebases looked very similar. The guy doing this wrote something like 30 posts a day on the discussion board about Rybka, and was clearly not a fan. They should have made a 3-way comparison - Rybka's PST, Fruit's PST, and some independent program's PST (in the same format as the other two).
