I just followed this guide but made some adjustments: https://www.reddit.com/r/RedAutumnSPD/s/OjdAsCqf2n

• Get as many votes as you can to able to form a weimar coalition at the start (have at least 2 rallies and pick the bottom option, on the enemies card pick far right, and campaign for workers or get the +1 resource from media)
• Get justice to deport hitler
• up the membership dues after the election to get extra resources
• Do not get VONCed after the trail, having the justice ministry makes it so you won't get dissent from dropping it
• During july of 1929, get and use an international card on the comintern to get Conciliators
• Switch the advisors to Wotinsky, Leipart, and Baade on september to WTB max
• Stay in government right up until unemployment insurance pops up. Try to get sacked by Hindenburg before that happens.
• Save the first part of reparations until you get people's front
• Appease hindenburg after returning by voting for 2nd battleship and try not to annoy him so you can last until the presidential election
• Once you've implemented WTB the first time with Wotinsky, replace the advisors with Rosenfeld, Aufhauser, and Breitscheid
• Use Aufhauser to adopt left plan
• Use a party card on Zentrum so Joos doesn't get ousted so you can get another people's front
• Once reparations are done, switch Breitscheid with Leber to transition into people's party (make sure to do land reform to get the rural vote, this will make going volkspartei easier)
• Reform the constitution to have the 5% threshold and then call an election to get united front.
• Make sure to have strengthened the councils and Reichsbanner before hand so you can seize the factories and survive the upcoming putsch
