You know your a go addict when every go game go’s like this for you.
… one board just doesn’t do it for you anymore 
I‘d play Tengen for sure 
If your arms are long enough! 
… your hand looks like this whether you’re holding a piece or not 
… Grandma asks you to speed up her computer and, during the installation of her new CPU, you just can’t help yourself 
Or you install a dedicated graphics card for her with a similar scenario. If she is a heavy gamer. 
You know you are a go addict when you enter a voting booth, examine the ballot, and, distressed by the obvious imbalance of power, you shade in enough circles to even things out. Plenty of indiscriminate pincering and counter-pincering.
And thus go begins to undermine democracy. Hey, nobody said this stuff comes without a price.
… you think the fighting, lasers, and explosions in Star Wars are amazing, but know the series could be completely elevated to new heights, if they but handled the battles in a different format
… you see the potential in every stone you pass 
Dupont Circle, a small park in a street circle in Washington, DC, has (or had, I haven’t been there in 30 years) chess boards engraved in stone furniture like this.It was a very popular hangout for hustlers who would play for anything from $1 to $5 per game. They were fairly strong, ranging from 1700 to low expert level I would guess.
Cordless angle-grinder… 
…when you’re supposed to be studying but instead you play go.
or when your parents have to drag you off the computer because of go.
I would say rather:
You know you are a Go addict when your grandchildren can’t drag you off the computer because of Go.
… when your parents are long dead, and you don’t have kids nor grand-kids, so you just play Go 
BECAUSE* you just play Go 
…In all honesty, seeing Palpatine play simultaneously against 4 Jedi masters and come out on top would be just as jaw-dropping as the actual scene.
(Come to think of it, all of the Sith Lords have been shown fighting against multiple Jedi at once. Perhaps the Dark Side hijacked AlphaGo for their nefarious plans…)
Kylo Ren doing nuclear tesuji also sounds hilarious
