# taking gote in error

The difference between Sente or gote can be large. If you do the same thing in gote that could also be done in sente, that is a big difference - you lose a whole move. Players obviously will prefer sente sequences, other things being equal.

Example:

Black gote

(We assume that the region to the right is Black's territory.)

takes gote. White has made a local gain. Black's threat is at a, OC, which transposes to the next diagram.

If Black plays first in the original position, captures the stones. But now if , Black will not respond at . This shows why is gote in the above diagram.

Black sente

By the sacrifice of , Black takes sente.

Question: In this position White plays elsewhere, has Black taken sente? Or to put it another way, is this a very good example of the subject in question. I don't say that I am right or wrong, only that I am unconvinced. Black's best local follow up seems to be at a, which is not obviously a must answer move.

Black gote

Miai analysis follows. 2nd diagram is the questionable part, as black may have better alternatives to . This analysis presumes and are sente.

Referring to the second diagram below this text. Added a pointer next to the diagram.

Definition: B gote: B=0
W gote: W=7

Whether black plays or not can be disputed.

Expectation = A(B=0, W=7) = W=3.5
Let 1-2 and count the score. If W takes gote, W=6

[This diagram has been edited. Previously, black mistakenly got the - exchange in sente, which is impossible.)

If B takes gote, either B=1 or W=2, ie. W=0.5.

A(W=6, W=0.5) = W=3.25, which is less than W=3.5 for white. Black does not take a loss by answering white's first-line jump. QED.
