and taking 3 stones yields an eye (it s important to add, as if there was only 2 it could be a false eye)

Sometimes even taking three gives a false eye.

<p>I have found a possible problem in this joseki, see josekipedia:</p>

<p><a href="http://www.josekipedia.com/#path:qdttocrdreqcpdpbrcrbsdobnbncmcndmbpcodsb" rel="nofollow noreferrer">http://www.josekipedia.com/#path:qdttocrdreqcpdpbrcrbsdobnbncmcndmbpcodsb</a></p>

<p><img src="https://i.sstatic.net/R8S2k.png" alt="enter image description here"></p>

<p>They comment this white's move as "Makes life". But it seems to me that white is dead actually - what about this sequence?</p>

<pre><code>$$c Black kills white?
$$ ---------
$$ ...3412.-
$$ .XXOO5OO-
$$ .XOXOOX.-
$$ ..OXXX.X-
$$ ......X.-
$$ ........-
</code></pre>

<p>So that T18 move seems like a big mistake. White perhaps should have played R19 instead and go to a ko fight?</p>

<p>So is there a mistake on josekipedia or did I miss something?</p>

White Q19 is a mistake. The correct move is R18. Then Black can't connect at Q19 because the stones would still be in atari.

```
$$c White survives!
$$ ---------
$$ ..63512.-
$$ .XXOO4OO-
$$ .XOXOOX.-
$$ ..OXXX.X-
$$ ......X.-
$$ ........-

```

After the capture, **a** and **b** are [miai](https://senseis.xmp.net/?Miai) to make White a second eye.

```
$$c Resistance is futile!
$$ ---------
$$ ..Oab.O.-
$$ .XXOOOOO-
$$ .XOXOOX.-
$$ ..OXXX.X-
$$ ......X.-
$$ ........-
