Warning: If you can't solve this problem within a 2-hour period, please stop solving or you will go mad!White mates in 21. qb3 after 2 minutes, can t see the following

1 qb3 nc5 2 rxc5#

1. qb3 after 2 minutes, can t see the following

1. Qb3 d1=Q!!!double check from rook and queen

double check from rook and queen

Yeah, but it's not mate, you have to find a mate in 2 to solve it.

e.g.

1.Qb3 d1=Q

2. Rcd4+ Kc6 or 2.Rc5+ Kxe4

Asorki, are you sure this is correct? It's not the same as the one I solved.

Saw 1.Nf4+ Nxe4 2.Nxe7++

@rstoledo 2... Bxe7

Asorki, are you sure this is correct? It's not the same as the one I solved.

Yah. This is slightly different. The original composer's idea will be revealed here.

Everybody please keep on solving. I don't want to sleep until this puzzle is solved. It's already 1:40 Am here in the Philippines!

What is the point of problems in impossible positions? White has 16 pieces + king + 3 pawns, therefore position could never arise; what possible

practicallesson could one learn from this nonsense?1 qb3 nc5 2 rxc5#

I guess that was a big fail as the knight is pinned at b7 and it isn't mate as black can play 2...Kxe4

I'm trying to find a solution, but so far no luck. The position can never arise, but still a funny problem

What is the point of problems in impossible positions? White has 16 pieces + king + 3 pawns, therefore position could never arise; what possible practical lesson could one learn from this nonsense?

The practical lesson here is:

How to solve impossible position without the help of an engine!Because of the availability of many solving machines (engines), many people now tries to ask the help of computers to solve a particular chess problem.

The maker of this problem intentionally put more pieces than the usual we've seen on the chessboard. This is to discouraged cheaters and engine users. Only the real solvers are welcome here.

As I've said this problem is very very difficult! Solving this will bring a smile to a solver's face. This is not a Problem composing competition. We're just having fun here!

Now please try to solve it if you want.

Again, stop solving if you cannot find mate in 2 within 2 hours or you will go mad!Analizand pozitia observ:albul are 20 piese:1K;2Q(+1);4R(+2);4N(+2); 6B( din care:2B black(+1) si 4B white(+3) +3 pawns =20 pieces; prin promotie puteau rezulta +5 figures nu 9 !!!de unde inca 4? Apoi negrul are pioni dubli pe coloanele : f (f3;f4) h(h3;h6) si b5;d2;e7 =7 pawns dar inaceasta structura trebuie sa aiba loc cel putin 4 capturi de piese albe!!!intrebarea este catepiese are albul? 16 sau 24?

CONCLUZIA: POZITIE ILEGALA!!!1.Re5+ Nxe5 2.Nxf4#, but unfortunality no mate after 1.Re5+ Kxc4

Thanks for the observation

Geticus. You share common sentiment withrenalboy.For the explanation please read my post # 15.Nb6 Rd4# (rook from e4, dunno how to note it)?

Nb6 Rd4 (rook from e4, dunno how to note it)?

Then Black king can escape at either c6 or e6. Please try again.

I wonder who can solve this very very difficult puzzle.

Don't use an engine please. Let's have fun!Here again is the diagram:White mates in 2
