Hello Bot

HelloBot is a go-playing computer program written entirely in Java by Ed Poor. It always beats IdiotBot and BeginerBot and usually beats WeakBot50k; it will even close off territory.

2013 - This summer's improvements include:

1. incorporation of Benson's algorithm to determine pass-alive units.
2. improved detection of dead stones
3. ability to read out ladders, both diagonally and on the edge.

So I guess it's about 22k.
