# Thread: Baffleing Chess Problem! | Forums

1. Dear GM,

I am baffled by this chess problem from 1001 Winning Chess Sacrifices & Combinations. Can someone please help. Thanks.

White to move & win: (Interference)
r1r3k1/pb1q1ppp/1p6/P1pp4/3P4/Q1P1PN2/5PPP/RR4K1 w - - 0 1

3. I'd like to set this up on a real board. Can I assume that the lower case pieces are black, and the upper case pieces are white? Am I starting to set up the board from the 1st rank or the 8th rank?

4. What in the name of whatever, does that mean
Could you write it in english please, and not that olde english whatever

5. The above board setup was actually output by CM9000 in FEN format! lower case=Black, upper case=White. w=White to move

6. Its called FEN, and it is part of the PGN standard for notation of chess games. Its usage is very common.

8. The solution is a6. It wins a pawn. There's no checkmate in x number of moves in this game. It's just a matter if you can see that a6 wins a pawn or not (all other moves doesn't win anything).
I get Fritz 8, Crafty and The King to evaluate the position around 1.25. It doesn't win for white in the way of checkmate but the position seems promising.

The sloution in the book ebutaljib, is also just a6 as far as I'm concerned (you can download all the positions from various sites as a pgn file).

If you want a line of moves that gives a win for white by checkmate I hardly think even Kasparov could come up with it. I think we can just conclude that white is up an extra pawn after a6 and has good winning chances

9. Nor would I. I need at least an extra queen and a simple position. There's nothing worse than claming a win and then end up losing
An one pawn isn't very winning in my book either. Should black then claim a win after e4 e5 f4 exf4

10. It appears that White wins a pawn immedately by a6, however, position of Black is such that take it back in few moves later plus more White pawns.

One thing remains: in 1001 compilation of games there are many many positions which begin with a surprise move, or a surprise move takes place shortly after preparartion, but in most of these positions when analyzed by CM9000 unfortunately CM only thinks in terms of material first rather than creating an amazing combination.

So I still think there is a great combination hidden in this game other than simply a6 and be happy with a pawn ahead for few moves!
