usually they wont put it on the cluster unless you tell them the move because the think youre cheating... which they accused me of when i did the same thing. im very strong postal player and i dont really see any strange tactical devices at first glance.

I don't know if this is the hardest position or not, but it reminds me that I have discovered a lot of positions that she has a very difficult time analyzing and assessing.

Should I interpret this problem as "black to move and draw" ?

I think I have seen harder test positions before.
