01 Opening
Matchley beat 1 of 5

Matchley the red squirrel always carries two acorns, one in each paw. They are exactly the same size, the same shape and the same shade of brown. She likes to hold them up side by side and ask whoever is nearby, "Same and same. Which one wins?"

02 Matchley
Matchley beat 2 of 5

In BluffForge, the answer is neither. When two pieces of the same number meet, both turn over and both go home.

Most players treat that as a waste: two pieces gone and nothing gained. Matchley treats it as one of the most useful tools on the board, because the trade itself might be even, but the board it leaves behind almost never is.

Late in a twenty-piece game, Red and Blue each had exactly one 8 left. Red's 8 was guarding the middle. Blue's 8 was creeping along the edge toward Red's back row, where Red's Moonstone was hidden behind a single bramble.

Matchley beat 3 of 5

"If their 8 gets near our back row, it'll find our Moonstone," said a worried Red piece.

Matchley didn't look at the 8 at all. She looked past it. "What does Blue have behind their 8?"

They checked. Two squares behind it waited a Blue 3, one of the badgers, the only kind of piece that can clear a bramble. That was the real danger. A bramble sends home any piece that bumps it, except a badger. If the 8 opened the way, the badger would follow and clear the last thing standing between Blue and the Moonstone.

Matchley beat 4 of 5

"And what do we have behind ours?" Matchley asked.

Red had a 9 waiting one square back.

Matchley held up her two acorns. "So picture it. Our 8 meets their 8. Both go home. That part is even. But afterwards our 9 is free to move, and their badger is standing alone with nothing strong to protect it. A 9 beats a 3. So the trade isn't even any more. It is good for us."

05 Closing
Matchley beat 5 of 5

It felt strange to send a strong piece to a meeting it could not possibly win. Some of the Red pieces shifted uneasily. But Matchley was calm. She wasn't counting the pieces on the board right now. She was counting what the board would look like one move later.

Red's 8 met Blue's 8. Both turned over, and both went home. Red's 9 stepped forward and sent Blue's badger home too. Without a badger, Blue could not get past the bramble, and Red's back row was safe for the rest of the game.

That is Matchley's rule. Two pieces of the same number both go home, so the swap is always even. What happens next often isn't. Before you trade, look at who is standing behind each piece, and trade when the board you leave behind is better for you than the board you have now.
