The most important TB is the Nalimov TB . Almost all good GUI could use them , The complete set 3-4-5-6 is 1.2 Terabytes !!!! If you don 't have a 2 TB hardrive like 95% to 98% of us, you don 't need to download the complete 6 men TB (TB improve the endgame play of chess engine, they play the perfect endgame). Nalimov 3-4-5 men Tb should be enought for most of us ( 7 Gb !!! It should be ok with big hardrive now ). If you don't have enought space for Nalimov 3-4-5 men TB (7 Gb) , it ' s fine you could download only the 3-4 Nalimov TB (70 files and only 30 Mo). Some Nalimov 6 men TB fan created a superb forum and share the 6 men TB with e-mule , you could find the 6 men TB online project  here TB Online .The e-mule project was created back in 2005 . Now they have the complete Nalimov 6 men TB with the last 16   6 men TB missing (122 Go) . Good luck to collect 1.2 TB for End game fans !!!

• The complete Nalimov 7 men TB is not for soon with the lack of hard drive space and for the good reason that Pr Nalimov and Kadatch have to generate them before to release them to the EGTB fans .
