Remarks:
1.Programs were tested with EPD2WB utility(pre-release of v.02) by Bruce Moreland.
2.No EGTB's were used.
3.For some specific engines, which does not output promotion piece while thinking (Nejmet, Comet, Zchess, Ant, Inmi etc.), results were checked manually.
4.EPD2WB does not support Beowulf, so its test results are from text mode command "test"
5.EPD2WB does not support Arasan, so its test results are from program "testsrc"
6."+" indicates new results
7."-" indicates older versions
8.In position N21 why white can't play Rf6!?
