Well I find it quite awkward that white's bishops gone and he still has his e and g pawns in their starting positions. And since white still has a rook and a bishop left, while black has only his king, I would say yes, white has promoted a pawn, maybe even more. Or black could just have been a retard.
I can't say however, to what white has promoted, nor do I have a clue as to how I can find out. I wait to be indulged.
Ow and by the way, I would certainly not mind more of these puzzles. Since you inquired.
there has been a promotion and it was the bishop.
A White pawn premoted into a bishop (that moves on dark squares). The last move was:
Nice find, amiraz, but actually, there is a little more to it (if only just a little). The position you give is illegal: black doesn't have a legal last move. The position below is a legal one leading to the position of the problem. It's just one of many, of course, (black could have moved any piece to f2), so we can't say much more than that there has been a promotion.
And I would like to see more of these puzzles. I always find them fascinating, if a little hard.
Incidentally, this position is legal, if black's last move was with his king, then so was white's.
So, I just found in a used bookstore a collection of deductive Chess Puzzles, which I thought I would share a few of here. That is to say, these aren't puzzles where you need to find the best move or what have you, but rather simply need to deduce what previous moves happened, or what piece should be on what position.
So, this is the first problem from the book, more an introduction to what kind of problems to expect. If you guys like these, I'll keep posting more of them.
Anyways, the question is, Has there been any promotion in this game? All you need to know about this position is that White is to move.
