So tricky, neat.

What's the proof game for this?

Hope this works:

Add a black bishop for a PG 4.0

chaotic_iak

Yes, it should be unique. [+bBc1]

Frankwho

Add a white bishop for a PG in 4.0

chaotic_iak

The location seems to be unique. The proof game isn't.

chaotic_iak

Oh wait, no, the location is not unique either.

Oh. Intended was +wBe5.

Unfortunately, that's not unique because the bB can travel via either c5/d4 or a3/b2

Frankwho

A fix?

Add a white bishop for a PG 4.0

Don't forget this classic. Solution(highlight): 1. Nf3 d5 2. Nd4 Nf6 3. Nc6 Nd7 4. Nxb8 Nxb8

Cooked; 2. Ne5 works.

Post #145: You are correct that it is a classic but sadly it is cooked.
