adum, it seems like alot of attempt have a19 played at the end, even when there's a stone there. since it's a new thing and since you always have it in attempts to solve new problems i'm assuming it's something to do with ppl solving using the test. applet... i didn't check it ^^*
update - okay, i verified it - when solving with the test. applet it auto adds a19 to the end of the attempted sequence...
