The SoC Training Academy and its Training Grounds provide basic training for new and old members looking to enhance their game strategy. "Train a Cook today, lose to a Sergeant tomorrow"
I'm no instructor but I'd try asking for help. Green doesn't want to lose so asking for anything is better than nothing. And hopefully you'll get actual advice from instructors.
This game has basically become a 3 player game. In a 3 player game, the 2 small players need to work together to knock the large player down. The alliance shifts each time any player becomes strongest, so it is a delicate balancing act. The only hope you have of surviving is to inform green of your intentions. Remember all communication must be in game chat, no pms or wall messages.
Try what oldrisky44 says. Another thing is that no spoils and flat rate are typichal block to block games. You avoid this if you play escalating style. Personally I hardly play any single games unless it's escalating.
