In a “dictionary” sense, what exactly is a “ko-threat”?
How to use it in a sentence?
From what I learn here:
You deem the stone important enough to fight the ko. You still have to play elsewhere (of course) but you try to find a move your opponent will feel compelled to respond to immediately instead of resolving the original ko (we call that a ko-threat). After that, you retake the ko stone and the fight is on!
So, to expand the sentence, may I say that all statements bellow are true?
- A ko-threat is a move
- A ko-threat is an important move
- A ko-threat is an important move you play that threatens something elsewhere that you hope your opponent needs to respond
- A ko-threat is a move that threatens something somewhere else that you play with the intention of making your opponent unable to fix the ko, so you can have the turn again and win the ko
Thus: “he played a ko-threat” means that “he” made an important move elsewhere with the intention of deviating the opponent move and having back the turn to play in the ko.
Am I using the term grammatically right?
Yes, the start is the same. This time however, White has something to threaten because there are other, not yet completely settled, stones on the board. White’s move (at D2) is what we call a ko-threat.
This puzzle is great.
Black can choose to ignore the threat and finish the ko but that means he will lose all his bottom stones now. The hard part of ko fights is judging who has more threats and how valuable they are.
So, next time I hear “this is a ko-threat”, I can finally understand that there is a ko fight somewhere else and the ko-threat is a move made to distract the other player from the fight, getting back the turn to play on the ko itself, wining the fight.
I hope I made sense of it, and if so, other beginners can also understand. But if it is wrong, please correct me there.
