Thank You Move / Discussion

Sub-page of ThankYouMove

Bill: About the definition, wouldn't induces be better than forces? I think that the concept is a bit more general than the definition given.


The following discussion was originally in Thank You Move.

Thank you move

A typical example is to peep at a one-point jump. It will normally cause the opponent to connect. But your stone, which is plastered against a wall of at least three stones, has very little value.

In the example, yes, Black will respond at B2, but what is the value of W1 afterwards?

On the other hand, for Black to be able to defend at B2 is quite useful. Although White cannot at this moment cut at B2, it is still aji. Black has gained more in this exchange than White has. Such a situation, where one player plays a forcing move (kikashi), but the other benefits, is called a 'thank you move'.

I don't think this example is exactly bad for White... Some peeps make good ladder blocks, depending on the situation.

Is my example at Do not peep at cutting points better? Please comment. Thanks.

BillSpight: I agree with unkx80. This example looks very much like a kikashi without loss. The white stones on the left look strong, and there is no obvious alternative. Besides, if White does not play W1, does Black really want to play B2?

There is a question of when to play the peep. My inclination is to wait, but it seems to largely be a question of style. Takagawa was a waiter, but Sakata likes to take his kikashi before it gets away.

The question of whether to play kikashi or not can be quite subtle. For an example, see costly atari.
