Seems correct.
I just startet a game against Crafty 19.15 in the Fritz GUI.
The Wb2uci logfile has only 2 "new" commands at the start of the game but with
logfile enabled I got 10 logfiles in the Crafty directory.
For example:
White(1): post
White(1): hard
pondering enabled.
White(1): computer
playing a computer!
White(1): level 0 4 0
White(1): force
White(1): d4
Black(1): d5
White(2): c4
Black(2): c6
White(3): Nf3
Black(3): Nf6
White(4): Nc3
Black(4): Be6
White(5): cxd5
Black(5): Bxd5
White(6): e3
Black(6): e6
White(7): Bd3
Black(7): Bxf3
White(8): Qxf3
Black(8): Be7
White(9): O-O
Black(9): O-O
White(10): Bd2
Black(10): Qa5
White(11): Ne4
