Hi Jon!

Now for something out of the ordinary



Diagram #1 | Black to move (to-increase difficulty)

KB6/QpN1p2p/rRpkP3/1Rp1p3/bqP5/brP5/pPP5/NB6 b - - 0 1

Diagram #2 | Black to move

KB6/bpN1p2p/RrpkP3/rbp1p3/RqP5/1QP5/pPP5/NB6 b - - 0 1

This one I don't understand.
Which one position of the two diagrams is leading to which one and how?
First one is clearly won for White, second one better for Black but maybe to be held by White after 1...Qxb3 2.Nxb5+.
Is this a study and what about the 52 moves

BTW this thread's getting too confusing to me because of its length. It's getting too difficult to allocate questions and answers,
