Maybe he has been playing Risk for a year B4hand...maybe 30 yrs...this IS the classic Rosk map so no suprises here for players just going electronic...
I';d played Risk for more than 20 yrs B4 entering CC-site and won a few here but basically, to me, the basic map is pretty pointless without face to face and a few lagers...
If it had been on a mor complicated CC-specific map, you'd have a good claim but looking at the game you didn't play super well (not bad but nothing a good Risk player couldn't combat) so you may have just struck a good Risk player starting out...
i think I've played a few multis over time but not really worth the hassle without absolute proof (the mods are not magicians)...so just foe and move on...
If it's any consolation and the player is an experienced board player just starting out on CC, he'll die of old age soon so you needn't worry too much...lol
