Once upon a time Adobe Flash was locked down. To make anything in flash you had to either buy or steal Adobe’s software to do anything with it. Nowadays though it seems that has changed. Using nothing but free software from FlashDevelop and GreenSock. I was able to build this chess software in about eight hours (knowing nothing about ActionScript at the start):

Ah, my son, Uber-hacker.
Congratulations, looks like fun!
You set up chess board wrong. Queens go on their color, ie. White queen should be on white square and black queen should be on black square.
Oops! You’re right. I don’t want to bother re-uploading it with the fix, but thanks for pointing that out!
