Fall 2017 engine tournament, 11 cpu , 60m+15s

[MikeB]

Yes, its a very nice tournament, and many positions that would be drawn are being played out and the games are decisive. Thanks for your time and effort.

Yes, very nice tournament. Here is an example from Fire - Texel that could have been drawn with different adjudication settings:
[D]r3r3/2q3bk/b1p1p1p1/1pPpPpPp/pP3P1P/P3P3/1B1R4/1K1B1QR1 w - - 73 94
Texel did not see 94. Bxh5 coming and quickly lost after that move. Before that move both engines thought the game was close to a draw.

Nice test position !
r3r3/2q3bk/b1p1p1p1/1pPpPpPp/pP3P1P/P3P3/1B1R4/1K1B1QR1 w - - bm Bxh5!;

agree

[D]r3r3/2q3bk/b1p1p1p1/1pPpPpPp/pP3P1P/P3P3/1B1R4/1K1B1QR1 w - - 73 94 bm Bxh5!

half of the tournament is played

It's a little early on, to draw conclusions about the top, but at the bottom, the three engines tied at 6.5, seem out of place.

half of the tournament is played

It's a little early on, to draw conclusions about the top, but at the bottom, the three engines tied at 6.5, seem out of place.

looks like 3 classes to me:

class one Houdini, Komodo, Fire and Stockfish
class two Fizbo, Shredder, Andscacs, Booot and Ginkgo
class three Nirvana Chess, Chiron and Texel

In class one, everyone seems to be able to win the tour
just my two cents....

class two Fizbo, Shredder, Andscacs, Booot and Ginkgo

With more games, I'm confident the big three will end were you'd expect. We'll see in 10-11 days.
