Check out puzzle number six ...
according to the site, white should play
1.Nxf6
because if black plays
1...Bxf6
white can play ...
2.Qxh7+ with mate waiting in the next move

However, they are assuming that black will simply play that very poor move, when in fact black has a winning move !!!

Thus they are advocating to play a bad move! This is often seen by weaker players, setting a trap and expecting your opponent to be able to do naught but fall for it. When in fact it is easily avoidable, and might even lose the game, if the opponent knows what to do!

Who sees the winning move for black after 1. Nxf6?

Not me, but I'm no good The way I see it, if black doesn't take the N at f6, white plays Qh7# next move, unless black plays h7, when NxR wins material...

Unless you mean Bh7 / RxR+, NxR / NxN, KxN / when black's still up a pawn...

Doing this without a board, I've probably missed the glaringly obvious. Looking forward to the answer.

easy ... Nxf6 , Qxf6 , Rxf6 , Bxf6 , Qxf7 , Bg7 , and black stays alive ... but hardly is black winning .. hes down two pawns and with the mobility of the queen will probably soon lose more .....

Yes poisenedpawn you are correct, black does not win, but still, they are assuming you will play one of the worst moves, which is a bad thing to do ...

Gotcha So here, "winning move" meant "less-slowly-losing move."

pp78 and javelin, do you do this stuff without a board? My visualization really blows.

for puzzle type questions ... yes i can usually handle most puzzles in my head , however it is often alot easier to do them on a board .. i tend to use puzzles for tactics practice but also for visualizing in my head , it helps to do puzzles this way .. as you eventually get better at seeing and planning your own games in your head

After Nxf6 Qxf6 Rxf6 Bxf6 Qxf7 Bg7 white will win easily, for example: Rxg7 Rxg7 Qf8+ Rg8 Qf6+ Rg7 Qxe5 followed by Qd6 and e4-e5. It is customary for problems to give solutions like this since Nxf6 Qxf6 Rxf6 is clearly winning, but on Nxf6 Bxf6 white needs to see Qxh7+! to win. They are not assuming that Black will play the worst move, simply giving the most obvious move as a line.

Another solution Black can simply move : h7-h6. White will take rook by moving Nxg8. Black can now decrease the pressing by capturing knight: Nxg8.

aznmonster .. if black plays h6 in response to Nxf6 , white will not take the rook .. but take the h6 pawn with his queen for mate in two . (RxR with assistance from the knight )

javelin The title of the page is "Combinations for material."
Out of the three possible moves to be made after Nxf6, Bxf6 is the one that doesn't lose material immediately :P I agree with you, it's not a good move they advocate, but there aren't good moves left to be made in that position :P
