What do I do in this position?

Ahh, the old "duck, duck, goose" gambit made famous by Berezowski in the 1955 Helsinki Chess nationals. The classic defense for this is to hunch down quickly.

Use the duck-sized horses

Play the bread crumbs gambit. Works every time.

Duck for cover.

Google Duckduckgo

It's hopeless, you're quackered.

This is pretty much book moves.

1. Duck

En quackant.

Quakers?!

go get a drink, it's a draw

Probably wait for white to move.

Flood the board. Most of your army will survive it

Duck army

Sacrifice a few bread crumbs early to improve your position

You're gonna need a lot of grapes....

and a lemonade stand

1. Take out bank loan
2. Buy Jeep Rubicon
3. Ducks are automatically transferred to dashboard
4. E4, mate in 6

Just grab on to some DuckTales.

Surrender to the supreme power of Duck

Youve got like 15 chocobos vs a totally default board, i think you just win.

Edit: I'm guessing your king has some pretty good materia, too. I don't know who let you load a save like this against an opponent this week, but it would take some pretty spectacular contrivance to lose this.

Rubber duck debugging

You gotta put down the duckie if you wanna play the saxophone 🎷🎶
