"What should I do (I'm white)" Literally shut up, nobody asked which race you are, in my eyes it's irrelevant. The fact that race influences chess so much is a symptom of inherent systemic racism in the world.
Ignore their reasonable critiques of your recent royal decisions and instead insist that you aren't backing down, even if the pawns are setting the chess board on fire and leaving the game. Start praising other kings to make yourself look good b by association.
I accused them of blackmail, called them 'noise' and 'landed gentry' and most of them came back. Thanks for the suggestion!
Pay some pawns money or other incentives to stay in place and not move forward. Then you can easily take care of the smaller portion of pawns that do get ahead. Plus you also sow discord among the pawns and divide them between sellouts and otherwise
Import white pawns across from the other tables, arm them with shields and force move black pawns out on the north side.
offer some pawns a position of priveledge in return for enforcing your hegemony by inflicting violence on other pawns.
Just hire some "counter-intelligence" chess-pieces to destroy their movement from the inside!
I hired some guy but he seems to be organising the revolution into a unified communist state and industrialising instead?
