ninja_gо_fast vs. BIG_P

you can see C6, according to AI, is not a good choice.
but later in that game you can see C6 plays important role.

what is this phenomenon called in human Go?

[〼Nyantori_Sedai〼]

It is called a ‘temporary bad move’

or

a ‘luck’

depends on how you view it.

[jlt]

A move which is locally good, but played at the wrong timing.

[Groin]

Luck maybe?

[benjito]

I do not think -3 in the opening can necessarily be called a bad thing either, except in the highest precision games. Even the move before it was considered to have similar value.

[ninja_gо_fast]

Please ignore my previous game. Let’s think of another example, where a very bad move ends up becoming the deciding winning move.

then asnwer the main question.
Thanks

@ninja_gо_fast

a very bad move ends up becoming the deciding winning move

Not going to happen, by definition. What will be deciding is a blunder (or many small mistakes) of the opponent.

[jlt]

It can happen if the bad move leaves some aji that the opponent didn’t detect.

A bad move that your opponent failed to punish.

[Crоw_of_astonishment]

a destiny of unlucky opponent

[Groin]

Doesn’t change, it remains a lucky move

[Crоw_of_astonishment]

what if the bad move is intentional, ‘I know this move is bad, but it has big impact if opponent doesn’t know how to punish it’

it sounds more like planned, not pure luck

[gennan]

If it’s deliberate, counting on the opponent making a mistake (because the correct response or refutation is not obvious), it’s usually called a trap or trick play in English, or hamete in Japanese.

[martin3141]

trick play

[Groin]

I completely agree about the trick side. But it can be unintentionally played, you play something you think it works but no it’s just it’s hard to refute and you don’t know. In that case you re still lucky! Although someone will call it hamete during the review…

[_KoBa]

Not sure if here is any proper word for that, but i know what you mean. Maybe one could call it “local loss for creating aji”? Or “accidental aji”? xD

And i also agree with the term “getting lucky” here ^^

[Groin]

Many times another word could be used to describe the situation although it’s not directly the same meaning but could have same consequences. I’m thinking of “overplay”

[SoumyaK4]

Its clearly the divine move
