.SYNOPSIS
|
|||
|
|
Local multiplayer chess game in PowerShell.
|
|||
|
|
|
|||
|
|
.DESCRIPTION
|
|||
|
|
Started off of code from https://github.com/bhassen99/POSH-Chess, which was very
|
|||
|
|
much incomplete. I kept the board shape, but have changed everything else.
|
|||
|
|
The unicode chess pieces unfortunately do not render in the base PowerShell console,
|
|||
|
|
they only appear when run in PowerShell ISE.
