[gnugo-devel] gnu go 3.8/3.6 bug report: PASS when should not PASS

[daviddatum]

I use GoGui:1.1.10 open this sgf file, 
send command: genmove b
gnu go return: = PASS,
but black should play at S4 or T3 or T1 to kill the white.
And after black pass, send command: genmove w
gnu go return: = T1, then start ko fight, at last the white win ko fight.
 
I try Gno Go 3.8 and 3.6, "genmove b" return "= PASS".
 
GoGui command: gnugo.exe  --mode gtp
