re: Another win for AlphaGo

Not seeing why it liked Caro Kann over Ruy Lopez as a response to King's Pawn.
Only 6% net victory for black vs 12% with RL. (4w-1L vs 6w-0L) in the sample (50 as black).

Although CK has a lower percentage of allowing white wins than the RL (50% vs 52%), the Sicilian games are wayyyyy better for that (32%, 30%, & 22%).
In fact, the CK gives white the second highest win percentage when including the full 100 game sample (50white and 50black). So, why in the hell play it as black?
But I guess as black, there are more potential loss scenarios with the Sicilian.
However, variation B30 is by far the best game for Black in minimizing White's chance to win versus KP opening.

Additionally, the use of English Opening and Queen's Gambit are shocking based on the statistics.
Middle of the pack in wins. Bottom half in overall win percentage. Bottom half in wins and overall percentage based on openings without a loss.
It's just very hard to see any particular statistical reason for its preference.
Additionally, the EO gave it the most wins when playing black!!!! So, why would it choose to play it as white?!?!
Could it be that it has "human-like" preferences. Where it is just more interested in those games?
Or... that it is studying those games more deeply, or assessing/exploiting weaknesses in the Stockfish gameplay?

I'd love to see what the Grand Masters say about it!!!!
