Common Double-Sente Endgame MoveI'm sure everyone has seen this position in a lot of their games and most know that it is referred to as double sente. 'a' is sente for black and 'b' is sente for white.

What I have been wondering about is when this move is truly sente and when it is not. Responding locally is obviously pretty big, but it seems like the follow up move value is only about the value of a monkey jump.

So just like how you don't need to jump to defend the monkey jump I don't see why you need to automatically assume you should defend against
. But still I respond to this all the time and I see a lot of other players defend this right away, even in the early middle game or the opening, when they otherwise wouldn't defend the monkey jump.
So what I'm wondering is, when should
be responded to and when should it be ignored? Clearly
is big, but you don't see pros playing this until yose starts.

Yeah, I struggle with this a lot. I often find myself responding to these types of moves (and monkey jump threats too) when there is still a lot of the board open. I think my problem is that I don't read to see how I can respond so I just respond now so I don't have to put in the work later. I think reading for this would be really important. In a close game you should probably take the time to evaluate the position and try to judge if you have a bigger move elsewhere (and I should too
).

This move is not the same value as a monkey jump. Because the stone is already connected by a first line "tiger's mouth" it is actually harder to stop. Surrounding stones also really matter when it comes to determining the value of this move, but to just say that it's the same as a monkey jump isn't accurate. I couldn't find an exact value on Sensei's for this follow up, but I'm sure it's better than a monkey jump - the question is, by how much?
The problem with this is that the statement in the thread about monkey jumps has little to do with what the user wants to know. They want to know when to respond to or ignore a first line move. They know that they can ignore monkey jump threats and are making a comparison. However, BackSeatThreader has decided that a discussion on the value of this move is more important than knowing when to respond to it. Now, that's not totally off-base. Knowing a move's value can help determine when to respond, but it is also not what the original poster wanted. This sort of thing happens and then the discussion moves to how many points the play is worth and the original question is never actually answered or brought up again. However, the thread was not "hijacked" because the topic is still related - in fact, the OP even talked about point values in his first post!
Some may even argue that EarlyYosePlayer is contributing less to this thread. All she said was "You should read" and that's advice people get all the time. However, she attempted to directly address the purpose of the thread. She did not ignore the question asked. She is participating in the discussion that CommonUser wanted to have.
Instead of ignoring CommonUser's question in CommonUser's thread, BackSeatThreader should have started a new thread like:

Value of the Tiger's Mouth JumpCommonUser posted about responding to the common first line double sente move and compared the tiger's mouth jump to being about the value of a monkey jump. I was wondering, what is the value of this move? I couldn't find a point value on Sensei's.

This is great. He makes reference to the post that inspired him to start this so others can see the discussion there, and he asks a clear question in his own thread.
Now, if BackSeatThreader genuinely wants to help CommonUser in his quest for the answer to his question, and feels that knowing the point value will do this, then he should not dodge the original question but instead embrace it in his post so that others know what the point of the thread is.

I think the key to answering the question of "when to respond" is knowing how much this move is actually worth. It may be similar to a monkey jump, but I think it's more valuable - the stone is already connected back by that first line tiger's mouth. Depending how late into the middle game you are it might still be sente. I didn't see anything on Sensei's, but does anyone know the value of this move?
