There is a difference when playing the game at set time controls and allowing
the computer to select it's move than there is in watch mode.
Example:

18. My H when set at same time controls and playing the game over exactly as
odell played it will play 18. h4 (1.67/8 72) However in watch mode looking at 4
or 5 moves seems to prefer Bxh6.

19. This was one move I never expected but at time control H played it changing
it's eval at the very last second 19. g4 (1.07/9 211).

20. Again no problem here gxf5 (1.90/8 196)

In watch mode seems that even when it reaches the same depth it can produce a
different best move from what it played.

I would like to know if anyone can repeat 21. h5 or 23. Kc1 in either watch mode
or play mode at the depth indicated.
