# Chess 2: Missing Piece

These chess problems require you to understand the rules of chess.

Expected difficulty MediumComment/E-mail if you want a solution to be published

Stipulations a) On what square was the rook on f1 at the beginning of the game? b) What color and piece is on h2 (the black circle)? Mention all pieces that can be on that square. (Just so part a is well-defined, I assure you at least one piece works.)

So here’s another one, which I should say is the best piece I’ve ever composed to date. (Yes, if this is the best piece then you know how beginner I am in compositions.) I might post some problems that aren’t composed by me, but I find interesting nevertheless…

Tough one. a) I think the rook was on a8

• You need your reasoning too. What makes you reason that the rook was originally from a8?

(Hint: he’s asking you for your reasoning because you’re wrong. Ask yourself: How did Black just put White in check?)

Rich position you have here! (I’m glad that this time the algebraic notation immediately determines which side of the board everyone’s seated on.) Part “a)” I took down quickly, but part “b)” I’m still working my way through. There’s a LOT of ordering going on – I’m suitably impressed.

Bg1 = promoted a2-pawn (Original Bc1 can’t get out) Only promotion-square is f8 or h8
To f8 is 5 captures all on light squares + exd3 also light square (Black: 9 on board – 6 captures – 1 spare) Last move was g2xf1=R this cost 4 captures from d7 + axb and fxg (White 9 on board – 6 captures – [Bc1] = 16) So the spare is black and can only be Bf8. Now it needs careful play to let bK and wB and bB out, and let wR and wB get to h1 and f1.
I give you a possibilty, started from PAS (Position At Start)
