I tried a game Yace vs. Yace. First try was exactly this line. I tried again out
of curiosity. With rather large thinking time, 40 moves in 1000 minutes. The
game took 2 days, and white won. Instead of 3. h3 (counting from one in the
original position) 3. Nf3 was choosen, with slight positive score. With the long
thinking time, it was seen now, that 3. h3 gives a draw score.

1-0 {Black resigns}
The game was not done under "clean" conditions. I used my computer for other
things, some of which also needed a significant amount of CPU time, now and
then. But at least 50% (probably more) will have been for the game, and most of
the time 100%.
