[Home](./index.md) > [bitburner](./bitburner.md) > [GoAnalysis](./bitburner.goanalysis.md) > [getLiberties](./bitburner.goanalysis.getliberties.md) ## GoAnalysis.getLiberties() method Returns a number for each point, representing how many open nodes its network/chain is connected to. Empty nodes and dead nodes are shown as -1 liberties. Takes an optional boardState argument; by default uses the current board state. For example, a 5x5 board might look like this. The chain in the top-left touches 5 total empty nodes, and the one in the center touches four. The group in the bottom-right only has one liberty; it is in danger of being captured!
\[ \[-1, 5,-1,-1, 2\], \[ 5, 5,-1,-1,-1\], \[-1,-1, 4,-1,-1\], \[ 3,-1,-1, 3, 1\], \[ 3,-1,-1, 3, 1\], \]
