Apparently, it doesn't always happen. I can fully reproduce it in the original tournament I had set up, but if I make another similar tournament, things work as they should. I'm afraid this means that even the people claiming things work for them aren't safe, since it's more or less random (I'm guessing an uninitialized variable or something like that), and they will get bitten later even though it seems to work at first. Another data point: This is how it looks when it works correctly: Sjeng: < uci id name Deep Sjeng 1.5 id author Gian-Carlo Pascutto option name Hash type spin default 165 min 1 max 495 option name NalimovPath type string default c:\tb\ option name NalimovCache type spin default 4 min 1 max 495 option name Ponder type check default true option name MultiPV type spin default 1 min 1 max 60 option name CPUs type spin default 1 min 1 max 1 option name Drawscore (centipawns) type spin default 0 min -75 max 75 option name Anti Human mode type check default false option name Personality type string default <empty> option name Store brain type button option name Load brain type button option name Clear Hash type button uciok < setoption name Hash value 128 Allocated 4194304 hash entries, totalling 134217728 bytes, in shared memory. < setoption name Ponder value false < setoption name NalimovPath value d:\crafty\tb < setoption name NalimovCache value 16 < isready readyok This is how it looks when the bug occurs: Sjeng: < uci id name Deep Sjeng 1.6Y id author Gian-Carlo Pascutto option name Hash type spin default 165 min 1 max 495 option name NalimovPath type string default c:\tb\ option name NalimovCache type spin default 4 min 1 max 495 option name Ponder type check default true option name MultiPV type spin default 1 min 1 max 60 option name CPUs type spin default 1 min 1 max 1 option name Drawscore (centipawns) type spin default 0 min -75 max 75 option name Anti Human mode type check default false option name Personality type string default <empty> option name Store brain type button option name Load brain type button option name Clear Hash type button uciok < setoption name Hash value 1 Allocated 32768 hash entries, totalling 1048576 bytes, in shared memory. < isready readyok Notice that not only is the hash not set, tablebases are disabled too! -- GCP
