Hey

Hey - my puzzle showed up again ! Does anyone know if there are any Novag chess computers still in existence?

Ever wonder how we got to over 100,000 problems?

It looks like you sacrified 2-3 pieces to get this position

I wonder what were the former moves, or the whole game from the beginning. Can you provide us with it?

actual game?

How have you moved your f8 bishop behind the untouched pawns.

The pawn on e7 shouldn't be there. The position is possible but it is very unlucky with that pawn there.

possible check.

the king though it looks like he castled must have actually sudo castled as only a rook could get at that bishup without disturbing the pawns.if white wouldn't have got suckered with this mate he clearly should have won.

A Knight could have taken the bishop on f8.

My puzzle RECONSTRUCTED

To answer some of the comments about "how I got to this position?" - or "this is an UNLIKELY position". This is not my ORIGINAL puzzle that I submitted - my original is from last week November 28th if you want to see it. Someone reconstructed my original puzzle to use for today's puzzle. Even then, my original puzzle from November 28th was "altered a little" from the ACTUAL GAME - it's been so long that I can't remember the actual position in the real game, but if you look at the puzzle from November 28 (last week) that is about 95% of the actual position (from what I remember) although I remember moving the e4 pawn (actual position of the pawn in the real game) to e3 to "speed things up for the puzzle". As I mentioned in my comment of the puzzle I originally submitted - since I was playing a computer, it played all the way to checkmate, and I checkmated the Novag computer about 15 moves later - so there were some obvious defenses involved by Novag from the ACTUAL position of the game that did not allow mate in 3 !

Still, I bet you misremembered the position of that pawn, and it was on e6 or e5.

Otherwise, the black bishop from f8 would never have been able to escape unless it were captured by a knight: then the knight would either have to be allowed to escape without recapture, or it would have to be captured by the king or rook: and this would have prevented castling.

So, either (1) a knight was allowed in there and out again, and captured the f8-bishop without being recaptured, after which Black castled to get his king to g8 and his h-rook out on to the board (either to be captured, or to be still present on f6): or (2) it got in there, out and in again, and captured *both* bishop and rook, and still escaped, allowing the king to move to g8: or (3) it got in there, captured the f8-bishop, was recaptured by either king or rook, which subsequently swapped places by a manoeuvre which involved the black king going out as far as d7 to let the rook out, then all the way into g8 again, and one of White's two existing knights is a promoted piece: or (4) the black pawn on e7 should be on e6 or e5, to have let the f-bishop out, or else (5) an illegal move has been made.

Obviously (4) is the answer that allows for the fewest actual mistakes on both sides of play, rather than both sides having been totally random...

@jonellis and ivan_

@jonellis: One other possibility, that after a white knight captured a black bishop on f8, that it was recaptured by a black knight.

But I have to agree with ivan_, that although the position is technically possible, it's highly unlikely.

It seems that some people are just obsessed with picking at a position trying to prove that it's illegal or improbable, rather than trying to actually solve the problem.
