caranthir: I think, with the tiger mouth, bot (and many humans) likes Black's slightly better eyeshape. (Hane at T2 is more of an endgame aspect.) E. g. if White had a stone or position somewhere on the right side, with future attacking prospects against B group, then the tiger would be even better, but it's interesting that bot prefers it even on an empty board. I wouldn't be so sure if tiger really should be disallowed, but it's ok for me either way.
Tristram: on a generic board, AI slightly prefers making the second-line tiger mouth as the follow-up, and tenuki is also totally fine, so I think that the problem should end after the first move.
d4rkm4tter: Tiger mouth at S5? It is locally not good, because you might lose the hane at T2.
