The games of this damn Hydra doesn't impress me at all, but somehow it manages
to win. In many games it has a draw position but due to the unwillingness of the
opponent to draw, it wins.
I see that Hydra looks at very big depths 17-19 on the early middlegame and at
1-3 minutes only. Is these search plies like the Junior-ones that makes a
mysterious (for me) search or like Fritz's/Crafty's... logical search?
For example here on 1 minute search only, it has a depth of 18 (to see this the
text has to be copied to Chessbase GUI):
Ikarus can draw. Go Ikarus!
