Very entertaining idea !
What about 16.Nd5! ed5 17.ed5 Re8 (with the idea Bf8 if white doesn't reply 18.Bxf6)

thanks Ryan!
Sure, my pleasure. FYI, To put in a game or sequence or moves you click the same button as to enter a diagram. Only when the screen comes up, you click insert game/sequence of moves and follow the directions.
Nice move Gumpty... it's true the chess engines don't find it! And they don't refute it either.
Great idea. I've tried one Black defence you didnt cover, but still see a win for White:)
Well the story goes something like this.
For the past week or so, i have been re-reading one of my favourite chess books of all time, 'Secrets of Grandmaster Chess' by the legend that is John Nunn.
John is one of my all time favourites, and i love his books.
Anyhow, i get to a game of his that 3 yrs ago (the last time i went through this book) i had had written some analysis on, i had written in ink (like im always doing) some lines revolving round a sacrifice i had thought 'reasonable looking' , backed up with a few different lines..... I MUST STRESS....THAT THIS IS NOT A COMPUTER MOVE! in fact, i have (this evening) downloaded a few different freeware engines, and not one of them ranks this move even in the top 8 moves! (check for yourself!). To be honest it may well be refuted, i cant beleive that john would overlook this move, and hes the GM and im not :-)
However, i really would like it for you guys to tell me whether or not this move wins the game for Nunn.
OK heres the position after blacks 15th move 15...Bb7
Nunn now plays 16.Bb1, and after 16....Nd7 remarks ''I felt a good deal of relief when he played this move since after it I felt sure that white could gain a clear advantage.'' This is another reason why IF my move works, i think john must have missed it! White eventually got the advantage and won in 38 moves.
My move is 16.Nd5!? and i had written the following analysis....
''A nice line:16.Nd5! ed5 17.ed5 Rd7 18.Rf3! Bd8 19.Bf6 Bf6 20.Bh7+! Kh7 21.Rh3+ Kg8 22.Qh5 mates.....
if 18...g6 19.f5! Bd8 20.fg6 fg6 21.Qe6+ Kg7 22.g4! Rdf7 23.g5 Bc8 24.gf6+ Bf6 25.Rf6 Rf6 26.Qe7 Qe7 27.Re7+ Kg8 28.Bf6 Rf6 29.Rc7 and white is winning.....
if 18...Ng4 then 19.Rg3! is winning
if 18...h6 then 19.Rg3! is winning
Blacks best seems to be 16.Nd5! Qd7! 17.Nf6+ Bf6 18.Bf6 gf6 19.Qg4+ Kh8 20.Qh4 Rg8 21.Qf6+ Rg7....and white is a pawn up and should have a won ending.''
Did John Nunn miss a winning move?! or can you refute 16.Nd5?!
Regards Si (Gumpty).
P.S. if anyone can post these lines on a board so they can be played out on the board that would be great, im not sure how to do it :-)
