On Tue 2021May18 using xboard 4.9.1 + gnuchess, GNU Chess 6.2.7,
I played this game against the machine:
1. e4 e5 {-0.15/13} 2. f4 exf4 {+0.47/11} 3. Bc4 Qh4+ {+1.03/12} 4. Kf1 Nc6
{+0.66/14} 5. c3 Nf6 {+1.68/11} 6. Nf3 Qh6 {+1.24/15} 7. Bd5 Ne7 {+2.23/12}
8. Qe2
The machine never made its eighth move. By never I mean I waited more than 33
minutes, and still no eighth move. While waiting I pressed "Engine > Move now"
several times, yet still no eighth move. I believe this is a bug.
