Fastest possible 40 lines time?

Second thought sounds much better. This bot was just a try to write a basic AI and make a video of it. There's no real usefulness for it. More explicitely, it's not worth porting it to Tetris Friends. TF has much slower DAS and runs with 40 frames per second. So this bot wouldn't be able to sub 20 s there. Additionally, TF has VERY slow softdrop speed. This bot softdrops an O every 3rd bag in average, so you'll lose a lot of time. And you'd need to introduce a variable telling you how high the JLO stack is, so that you know how long you have to press down softdrop key.

Yeah that would make it much slower, but still an easy way to get top 100 on the site.

The height variable wouldn't really be difficult, it's just a matter of counting the height of the pieces as you put them down.
