Ng5+ fxg5, Qf7+ Qxf7,d7d8N check mate.

Easy. 1. dxe8(Q) wins. Let’s have something harder please.

A simple yet beautiful combination!

1.Ng5+ …fxg5 (forced)

2.Qf7+ …Qxf7 (forced)

3.d8(N)#

@anonymous (3:21):

1.dxe8(Q) …Be4#.

The puzzle wasn’t as easy as you thought.

1. Ng5+ 2. Qf7+ 3. d8N#

Tommy K. says:

1. Ng5+ fxg5(only move)

2. Qf7+ Qxf7(only move)

3. d8=N#

1.Ng5+! fxg5 2.Qf7+! Qxf7 3.d8/N mate it’s a very nice puzzle. Susan, you should really congratulate your children !

Nice.

1. Ng5+ fxg5 2. Qf7+ Qxf7 3. Nd8++

1. Ng5, 2. Qf7, 3. d8=N

Nice one.

1. Ng5+ fxg(forced)2. Qf7+! Qxf7(forced)3. d8=N mateSimple, but very cute. ðŸ™‚

Ng5+, Qf7+ and d8=N

looks like Ng5+, pxN, Qf7+, QxQ, N=Q++

looks like Ng5+, pxN, Qf7+, QxQ, N=Q++

1. Kg5+ fxg 2. Qf7+ Qxf7. 3.d8K mate

looks like Ng5+, pxN, Qf7+, QxQ, p=N++

I can see only one tactic that works, but it is a beautiful double sacrifice combined with a queen deflection!

1. Ng5? fg5

2. Qf7! Qf7

3. d8(N)#

1. Ng5+ fxg5

2. Qf7+ Qxf7

Checkmate, very nice !!

thanks susan

Ng5,Qf7,d8K

i think i got it…

1.ng5+ xg5

2.qf7+ qxf7

3. d8(N)# right?

Easy, but pretty.

1.Ng5+ fxg5 2.Qf7+ Qxf7 3. Nd8#

The eye is drawn to the battery on the f file since the black king will have trouble going either direction.

Ng5+ fxg5 f5 is covered by the bishop and f6 by the the pawns but Qf7+ Qxf7 d8(N)#

Sorry black king no where to go

White should avoid getting mated by giving some checks. It seems to me that Ng5+ – fxg, Qf7+ – Qxf7, d8P++ is mate.

1. Ng5! fg5 (forced) 2 Qf7! Qf7 (again forced) 3 d8=N checkmate.

Only took me half a minute to see. I guess I got lucky with this one.

I am not sure if it works doing this in a hurry

1. Ng5+ fxg5 2. Qf7+ Qxf7 3. d8=K++

f3-g5 ! f6xg5

f2-f7 ! d7-d8

e8xf7 mate

I’m going with

1. Ng5+ fxg5

2. Qf7+ Qxf7

3. d8(N)#

I guess:

1) Ng5+, fxg5;

2) Qf7+, Qxf7;

3) d8=N#, …;

Is it right?

ciao

Luigi

1. Ng5+ fxg5

2. Qf7+ Qxf7

3. d8=N#

It’s a mate after 3 moves via 1. Ng5+ fg5, 2. Qf7+ Qf7, 3. d8(N)+#

Ng5+ fxg

Qf7+ Qxf7

d8=N mate

easy one

Anon 3:21:00 must be that Jack A. Laffarty dude. Not only is he bad at chess, he is mean too.

1. Ng5+

Nice puzzle Tommy.

1.Ng5-fg

2.Qf7-Q:f7

2.Qf7-Q:f7

3.d8-Nx

I’m thinking

1. Ng5+, fg

2. Qf7+, Qf7

3. d8=N mate!

It is mate in 3 as follows:

1.Ng5+ fxg5

2.Qf7+ Qxf7

3.d8=N#

1. Ng5+ fxg5 2. Qf7+ Qxf7 3. d8=N#

1. Ng5# fxg5

2. d8(N)+ Qxd8

3. Qf7#

? right ?

1. Ng5+ fxg5

2. Qf7+ Qxf7

3. d8=N mate

1.Ng5+ fxg5

2.Qf7+ Qxf7

3.d8(N)#

Knight checks on g5, opening the f column. Queen checks on f7, sacrificing the queen. Pawn promotes into a Knight checkmating.

Nice little problem!

What a wonderful puzzle! Congratulations to its creators!

Ng5 forces Black to capture with the pawn.

Qf7 forces the capture with the Black Queen, clearing the way for …

d8=N#!

A beautiful conception!

kt to kt5 check, followed by Q to bishop 7 check, followed by pawn to queen 8, promote to kt is checkmate isn’t it? Sorry about notation, I don’t know algebraic.

1.Ng5+ fg5 2.Qf7! Qf7 3.d8=N mate!

I guess,

1.Ng5+ fxg5

2.Qf7+ Qxf7

3.d8N#

White Mates

A straightforward underpromotion.

1. Ng5+ fxg5

2. Qf7+ Qxf7

3. d7-d8(N)#

All moves for black are forced, so no variations.

1.Ng5+, f X g5

2. Qf7+, Q x f7

3. p d8 N#

A very complicated puzzle.

1Qxb6 seems to be the most promising.

got that in 5 secs

1. Ng5+! fxg5

2. Qf7+! Qxf7

3. d8=N#!!!!!!

Hope this is the solution

1 Ng5+!!! fxg5

2Qf7+!!! Qxf7

3 d8(Knight) mate

How about 1.Ng5+ fxg5 2.Qf7+! Qxf7 3.d8N#.

The Black king’s position relative to the advanced pawn strongly suggested to me that a knight promotion was the key idea here.

Nice puzzle by Tommy and Leeam!

1. Ng5+ fg

2. Qf7+!! Qxf7

3. d8N#!

1. Ng5…fxg5

2. Qf7…Qxf7

3. d8(N) mate

It is very tricky.. 1.Ng5+ fxg5 2.d8=N+ Qxd8 3.Qf7#. (1.d8=N+ also works).

1. Ng4+ fxg4 (only move)

2. Qf7+ Qxf7 (only move)

3. Pwan promoted to Knight and Checkmate!!

Alimuzzaman

White is totally toasted with threats of mate with black knights one move, if he does not keep giving checks. The ultimate idea is to use the whites pawn to underpromote to a knight followed by mate.

Greetings from India.

I hope i got it right. Nice underpromosion!

Hi Susan Polgar,

Clean,neat and shift suggestions by brainy minds here in this blog,kudos to everybody.

wow 89 comments so far, must be really a nice puzzle (and of course it is), nevertheless I would like to add to all the correct comments that the order of the moves does not matter.

White can start

Sg5+ fg5 and then play Nd8+ (which leads to Qf7 checkmate) or even with Nd8+ and then Sg5+.

By the way: Nice idea to prevent dxe8 at first by the answer Na5 checkmate. White must mate his opponent, since he otherwise can lose the game too.
