<p><b>New page</b></p><div>A '''Turbot Fish''' is a [[single-digit]] [[solving technique]] that uses a [[loop]] of odd length. The minimum length is 5, forming a fish-shaped pattern that gave the technique its name. Longer loops are possible, but they are better known as [[Fishy Cycle]]s.<br />
<br />
Here is an example of a Turbot Fish:<br />

The candidates in [[column]]s 2 and 5 are strongly linked. The pattern causes either '''r5c2''' or '''r6c5''' to be true. Since '''r5c6''' can see both these candidates, it can be eliminated.<br />
<br />
This pattern is also known as [[Skyscraper]].<br />
<br />
The following pattern is also a Turbot Fish:<br />

The candidates in row 5 and column 5 are strongly linked. The pattern causes either '''r5c2''' or '''r2c5''' to be true. Since '''r2c2''' can see both these candidates, it can be eliminated.<br />
<br />
This pattern is also known as [[2-String Kite]].<br />
