Attention: Adriandmen, BiggDoggProblem and Rooperi

Asorski

Hello Adriandmen, BigDoggProblem and Rooperi, this is my 52nd Problem. Please check this with an engine to confirm it's soundnessWink. To present the idea more effectively, I have no choice but to use obtrusive (promoted) pieces here.

The position is very complicated and I hope there is no other solution other than the composer's idea.

                            White mates in 2.

Yes, everybody can solve now but again this puzzle is awaiting confirmation. I want to know if there is only one solution.

My software cant do this, it has obtrusive pieces.

I haven't got any chess software installed since I bought a mac but Qxe4+ , Nxe4, Ne3# looks like it does the trick

Ok. Thanks, I think Adrian And BDP's software can do it.

No, solver's should not use an engine. 

Please try to solve this without using an engine.

And now: 1. Qxe4+ Nxe4 2. Ne3+ Rxe3!

Ahh yes, that would stop it Laughing

Hi Asorski-

Comp says there is no mate in 2. In particular, 1.0-0 is refuted by 1...Qd4!

What??Surprised

I only consider ...Qe5 and ...Qxd5.

Thanks for the info. This problem has no mate. You are correct, my intended solution is 1. 0-0!! but ...Qd4!!! defends. I need to improve this one. Sorry.Cry

Asorski

Sorry preachingforjesus, the puzzle has no solution as pointed out by BigDoggProblem. My solution is indeed 1. 0-0 but BDP's ...Qd4 defense totally ruins the puzzle!Cry

Checkmate by 2 moves..Rf6+ Nxf6; Ng7+ mate

Asorski

I believe this correction will work as after ...Qd4 2. Nxd4#. Please confirm.

In diagram 1 your first move (1. Rf6+) is not possible. It is illegal. I thought you intended 1. Rg6-f6??

I'm pretty sure that's now correct, Asorski  - I thought 1.Rf1 was good all along but not having an engine to check it, I missed 1...Qd4 at first as the best defense. It's that f6 escape square that's the problem & you've now closed it off !

Surely though, castling as a first move is no good because of 1...Qh1+ ?

Edit:  I see you've scrapped the castling option !

This is what I've got so far ....

1. Rf1 Qd4 1... Nxe6 2. Bxe4# (1... Qxe3+ 2. Nxe3# )

1... Nh52. Qxe4# 1... Nd6 2. Nxg7# )2. Nxd4#

1... Rfxe6 2. Bxe4#

Well, I think you've missed the Bxh1# in the castling key move.

Also, 1. Rf1 Rd4!! (White cannot play 2.Qf4# because of the pin).

why do your problems have to have so many god damn pieces?.
