How much Gigabytes the 6 piece tablebases without pawns need? > >Thx >Ingo Bauer Just to answer your first question: There are 365 theoretically posible 6-piece tablebases. These are made up of 1. 70 Kxxxx-K 2. 175 Kxxx-Kx 3. 120 Kxx-Kxx Dividing these groups into the tablebases with and without pawns: 1a. 35 Kxxxx-K without pawns 1b. 35 Kxxxx-K with pawns 2a. 80 Kxxx-Kx without pawns 2b. 95 Kxxx-Kx with pawns 3a. 55 Kxx-Kxx without pawns 3b. 65 Kxx-Kxx with pawns None of the tablebases in the first group are available, with or without pawns. Because of their relative unimportance they are the bottom priority, and I doubt they will be generated until the other two groups are complete. Groups 2a and 3a are complete. 35 of the tablebases in group 2b are available. None of the tablebases in group 3b are available. I'm posting my unofficial checklist of the EGTBs in group 2b. I've heard rumours that Eugene has already generated a batch of new EGTBs that he hasn't sent to Bob yet, so the list could be out of date fast. I hope so!
