This means DB's last move was Rca1, at depth 15, 89:24 remaining until next time
control.

"Qd8" was entered as opponent's move.

221 seconds for opponent to move.

Two changes of best move, from f4 +0.41 through Kh2 +0.42 to Bd1 +0.45. Ply
finished with eval +0.45 after 119 seconds.

>11(6) #[Bd1](43)#[f4](46)[TIMEOUT] 46  T=234

Best move changed again at ply 11 (+6 from the chess processors) to f4 at eval
+0.46. After 234 seconds, maximum allocated search time reached, DB plays its
move.

f4 is played at depth 14 (?), 85:39 left to next time control.
