In Response To: NOT a contentious clock question, but instead... (Chuck Bower)

(I flipped the board around.) As you can see, JF got this wrong by quite a bit. GNU-bg liked 8/4 at 2-ply eval and the rollout confirmed that. I probably would have played 22/18 like several of you did.
The score (after 2 games) is: JellyFish 2, Player2 1 (match to 5 points)
Move number 12: JellyFish to play 41

JellyFish 135

Player2 127
Position ID: wvMxBwBsboUBJA Match ID: MAGmACAACAAA

• JellyFish moves 24/23* 13/9

Alert: doubtful move ( -0.117)

Alert: lucky roll! ( +0.444)
