Chess challenge 37

White to move and mate in 3

DaveSun found a check mate in 2. Very impressive! :) 1. Rg4xg7+ Kg8-h8(forced) 2. Rg7-g5++

Let's see if anyone else can find it - (And his mate in 3 was correct also ;)

1. Rg4xg7+ Kg8-h8(forced)
(mate in 2. Rg7-g5++ but since rule states mate in 3)
2. Rg7-g8+ Kh8xRg8(forced)
3.Rb2-g2++

Darn! I missed Chess Challenge 37!

You can still have a go at it if you haven't read the answers yet.

I don't usually let on someone has the correct answer until I'm ready to publish the next challenge, but on this occasion I was impressed that DaveSun found a two solution check mate for 3 solution puzzle ;)

Ingenious! Well done again DaveSun :)

Mate in 2 is possible if:
1. Qd5-g8+ This is a gamble on the part of white that black will answer with Rf8xQg8. Blocking his own king. possible but not very likely.
White then completes with
2. Ne5-f7++
If Black takes white's Queen with his King instead of his Rook, mate will most likely go to black as white becomes no threat at that point.

Mate in 4 is a delay by black.
1. Ne5-f7+ Rf8xNf7
2. Qd5-d8+ Qb5-e8(delays mate by 1 move)
3. Qd8xQe8+ Rf7-f8
4. Qe8xRf8++

In response to Chess Challenge 38

Luke yes this would work, but Your second black move is not forced. Black could bring the Queen back to block, delaying your check mate by one more move. But you would get it in 4 as the white Queen takes black Queen and then your second (now third) move for Rook is forced, and Queen takes Rook for ++

DaveSun, I've screwed up here. There is no mate in 2, but a possible mate in three. My apologies. yes, you ++ would work in two, but as ever these challenges are based on the opponent making to work hard to win ;) Your mate is not the solution I have, but it works, it's fine :)

Chess Challenge 38, White to move and mate in 4.

There is also a mate in three which I will accept as a win instead of/as well as.

Hello Dear Friends!!! It's nice to see you all again, I've missed you!



On Number 38:

I thinks there's a flaw in the solutions so far. On Move 1, Black doesn't have to take the Knight with his Rook at all: it's not forced. Black can always move his King to g8 since the Knight blocks the Queen from her coverage of g8.

So to complete the answers, my solution is this one. :]]


1. Ne5-f7+; Kh8-g8
2. Nf7-h6+ (double check); Kg8-h8
3. Qd5-g8+; Rf8xg8 (forced)
4. Nh6-f7++
All is forced from beginning to end.

Well done Beets. Spot on! And so is your solution :)

You are quite right, it's all forced from beginning to end; it's known as a "Smothered Mate".

Beethoven wins Chess challenge 38 Well done :)
solution;
1 Nf7+ Kg8 If ...Rxf7 then Qd8+ forces mate in 2
2 Nh6+ Kh8
3 Qg8+ Rxg8
4 Nf7++ Mate

Well done to DaveSun for also getting a solution in 4, but it is not the 'correct' solution since it is not all forced as Beethoven points out.
The winning solutions are based on forced moves rather than relying on your opponent to take and option which helps you get the mate.
[edit] Any 'options' taken by your opponent may accelerate check mate to less moves, or to an unforced check mate, but the idea behind getting the correct solution is based on your opponent taking any options to stave off check mate for as long as possible.
Doh, what do I know about chess?

In the following challenge each move by the black King is forced or to stave off check mate for as long as possible.


Chess challenge 39

White to move and mate in 5.
