minor clarification

Richyfourtytwo: Created page with "The template: If the middle red piece is removed, t..."

2016-05-17T15:37:19Z

Created page with "The template: <hexboard size="4x5" coords="hide" contents="E *:a1 E *:b1 R c1 R d1 R e1 E *:a2 E *:a3 E *:e3 E *:d4 E *:e4" /> If the middle red piece is removed, t..."

New page

The template:

<hexboard size="4x5"
coords="hide"
contents="E *:a1 E *:b1 R c1 R d1 R e1 E *:a2 E *:a3 E *:e3 E *:d4 E *:e4"
/>

If the middle red piece is removed, the template stays valid, as long as the two remaining stones are connected in some other way.

(From: [http://www.drking.org.uk/hexagons/hex/templates.html www.drking.org.uk])

Red has two main threats:

<hexboard size="4x5"
coords="hide"
contents="E *:a1 E *:b1 R c1 R d1 R e1 E *:a2 E +:b2 E +:c2 E *:a3 R 1:b3 E *:e3 E +:a4 E +:b4 E *:d4 E *:e4"
/>

and

<hexboard size="4x5"
coords="hide"
contents="E *:a1 E *:b1 R c1 R d1 R e1 E *:a2 E +:c2 E +:d2 E *:a3 R 1:c3 E *:e3 E +:b4 E +:c4 E *:d4 E *:e4"
/>

For trying to block the connection Blue has to play on the overlap:

<hexboard size="4x5"
contents="E *:a1 E *:b1 R c1 R d1 R e1 E *:a2 E +:c2 E *:a3 E *:e3 E +:b4 E *:d4 E *:e4"
/>

First attempt (c2):

<hexboard size="4x5"
coords="hide"
contents="E *:a1 E *:b1 R c1 R d1 R e1 E *:a2 E +:b2 B 1:c2 E *:a3 R 4:b3 E +:c3 R 2:d3 E *:e3 B 3:c4 E *:d4 E *:e4"
/>

Red 4 is connected to the top by the two fields marked with +.

Second attempt (b4):

<hexboard size="4x5"
coords="hide"
contents="E *:a1 E *:b1 R c1 R d1 R e1 E *:a2 E *:a3 R 2:b3 B 5:c3 R 6:d3 E *:e3 B 3:a4 B 1:b4 R 4:c4 E *:d4 E *:e4"
/>
