Comment:
This was a position I encountered playing iGammon (v4.2). The tutor wanted me to play 10-5 when I wanted to play 13-10 6-4. I didn"t agree with tutor and played my move. The 10-5 is a blunder by iGammon at sixth position (so does not show here) with equity 0,715. But I was surprised that roll out showed one move almost equal (8-3) and one an error worth of equity better (13-11 13-10). I found them very aggressive. And looking at the numbers these moves are more GG-ish while the 13-8 move wins the most games (w/ less gammons) namely 65,44% and seems more GS-ish.
