But to the original discussion about TB's: it is just a piece of code every programmer can write, it is there, it is working and saves a lot of programming time. I don't see a problem as nothing creative is involved, just raw programming how to access data. To get TB's to work you don't even have to understand chess. By saying this I don't want to put Eugene's work down on the contrary but I consider the invention and creation of TB's itself as more important than how to access them. Ed
