General tips for a few achievements that aren't as self-explanatory:
TUSKS'S SCARING AGAIN, TUSK FLEES TO BRUSSELS, TUSK SELLS POLISH CAPITAL:
At the start of a 4-player chess match, repeatedly use a full-power "Deflation" attack on a King around 4+ times
TWO AGAINST ONE IS A TUSK'S GANG:
Move a coin to the center of the board and use the "Deflation" attack on it several times to enlarge it. Then, use a Wozdoopy Grenade to launch two coins towards the enlarged coin
TUSK CLAIMS THAT QWERTY ARE PEOPLE:
Use a pawn to capture the special coin that spawns at the center of the board
THE TUSK (D)EFFECT
Use the "Hot Sauce" attack on a piece, then move that piece to the center of the board. Use the "Deflation" attack on the same piece a few times to enlarge it. Then, use the "Invisible hand of market" attack on a Knight to drop the Knight on the enlarged piece. The achievement should unlock if the Knight fully bounces off the enlarged piece and lands back on it.
