<p>Mamling: Fix spelling</p> <hr /> <div>{{wrongtitle|title=a1 opening}}<br /> <br /> <br /> &lt;!-- &lt;hex&gt;R5, C5, Va1&lt;/hex&gt; --&gt;<br /> <br /> The '''a1 opening''' (in the [[acute corner]]) is one of only two openings known to be defeatable. The other is [[B1 opening|b1]].<br /> <br /> (This does not mean that these are the worst possible opening moves. Compare with the diagrams on [http://www.cs.ualberta.ca/~queenbee/openings.html the openings page at the queenbee site])<br /> <br /> [[image:acuteopening.png]]<br /> <br /> <br /> Due to the [[Symmetries (board)|symmetry]] of the Hex board, the same is true of the [[opposite hex]]es, but they are not usually referred to explicitly because their [[Coordinates (board)|designation]] depends on the size of the board. References for proofs can be found on the [http://hex.kosmanor.com/hex/theory.html Hex Theory] page.</div>
