AlphaGo Zero vs. Master; Game 6: Don’t worry, play tenuki
Sunday February 25, 2018
AG Zero is back, this time “with a big group that looks like it’s about to die, just floating around in the middle of Master’s moyo”
says Michael Redmond 9P in his commentary. “But Zero doesn’t seem to be worried, because it plays away and does all sorts of stuff.”
“Master vs Zero with Zero on black are especially great games,” enthuses viewer Stefan Kaitschick. “Master getting beaten with the common sense moves, while Zero does what it pleases, is something of a horror show.” Adds agazmenlyfzsys, “Alphago zero is just from another dimension.”
