Hi to all!

What commercial engines do not use 6 men tablebases?

Tanks in advance!

RYBKA wasn't using 6-man EGTs when it played ZAPPA in the ICGA WCCC 2007 (Round 3?). Neither was ZAPPA. RYBKA had a 6-man mate in 41 and ZAPPA managed to defend it. Ironically, according to the report in ICGA_J v30.2, had ZAPPA had the relevant EGT, it would not have made the move which was best for playing a RYBKA without the EGT (as this clearly led to being mated in 41): it would have done something worse and got beaten by RYBKA quickly.
