I’m so much happy to present 2 problems by Petko A. Petkov! My site will become half-year old on October, the 10th. Also, a year ago on the same day, I’ve written to Mr.Petkov for the first time and from that day trying to be a good student of him. These problems is one of the most meaningful gifts I ever had!   

Dear Petko, thank you so much for everything!!!

No.148 – hs#3 – White blocks realized by the black pieces!  – a very surprising  effect of Anti-Andernach Chess! (Author)

No.149 – hs#3 – A non-standard change of functions of two Chameleons, where “tempo moves of Chameleons have an effect as white block through the black piece” (JV)


Definitions:

Chameleon: On completing a move, a Chameleon (from classical standard type) changes into another piece, in the sequence Q-S-B-R-Q…  Promotion may be to a chameleon at any stage in the cycle.

Nightrider(N): A Rider along a straight line on squares lying a Knight`s move away from each other.

Anti-Andernach Chess: a unit (not King) changes color after its moves unless that move is a capture. (Or: a unit (King excluded) changes color on completion of a non-capturing move.)

    Two beautiful problems by Petkov.
    Two original and interesting effects of Anti-Andernach Black queen releasing guards around the White King is unexpected and paradoxical in No.148 !

    Black playing tempo move converting to white piece in N.149 is probably a unique idea ! Problems worthy of the World champion !
