Gaviota 1.0 x64 - Gauntlet Matches, 100 Rounds

The gauntlet matches for Gaviota 1.0 x64 against the selected top chess engines was started a few days ago but was aborted after seeing so many losses by time forfeit at 43.75% or 350 games. The previous version Gaviota 0.86 did not suffer the same behavior. This is the second occurrence of gauntlet matches that was aborted because of excessive losses by time forfeit where Chiron 2.02 had similar performance. A third should be from Arminius 14-01-18 which was tested earlier but was not reported. It should be noted that these engines were contestants in the current TCEC Season 6 Live Tournament and do not have serious problems. The probable cause why these engines do not perform well in the Owl Rating List is because they use the old Winboard Protocol which may not be 100% compatible with the new Arena 3.5 GUI. Most chess engines using Winboard usually gave me extra work to do just to run successfully in Arena tournaments.

This failed Gaviota 1.0 gauntlet matches will not be reflected in the Owl Rating List.
