Regarding the white pieces. It is advantageous for white to attack the Phoenix after its false reveal. And who else? There are no other obvious black pieces, it's random... but why, if there's an obvious enemy? The gray piece should attack the black piece. Again. Why, if there are quite obvious white pieces, and there are more of them? That is, we can see that we are targeting the white pieces. Then, the Gur is considered to be black/gray.
"If the Gur is white, and we guessed incorrectly, that's bad, of course. But it's important to know who we guessed. If it's Pawn F2, it's not a big deal. If it's something more important, then facepalm."
If it's Pawn F2, then the clue was incorrectly deciphered, and there don't seem to be any other options.

And one more thing. I don't recommend defending me; choose someone more worthy.
