Chess is next. Harry digs out the pieces he may or may not have borrowed from Sirius’ set. He puts them out on the board and uses engorgio to size them up to match the rest. Harry’s never been one for chess, but he studied as best he could to prepare for this exact moment. The battle is fierce, but Harry, thankfully, manages to get the opposition into checkmate. He shrinks his pieces back down and drops them back into his bag as he moves through the last door.
