Backround behind this:

Was playing arcanists at Funorb.com, I had the most epic game of my life, we were so evenly matched, and apparently there is a time limit on rated games (about one hour). We were so evenly matched we ran out of time... and my opponent said at the end,

"Baja con dios, mi amigo",

and I would like to know what it means.
