Say it.

We need your explanation.

Most engines never accept more than the usual pieces but some engines do!

Adriandmen a problem composer himself later admitted that he checked the puzzle with Apwin a solving engine, and it found the mate in 2! Not only that, Apwin confirmed the key move. That no mate is possible except with that amazing 1. Re1 move!!

No need. The host must continously checked the comment and quote it instantly and post it together with his reply.

Look at post No. 82 by Qweeni2 of France, I quoted her (#85) saying the position has no mate in 2. She deleted her comment when Scottrf published the solution! 

Adriandmen, I'm so happy about the turn-out of this forum!

In a span of 2 days more than 160 comments were posted and close to 50 people shared their thoughts. Even though the puzzle was through, visitors continue to post their solution thinking it's so easy but failed.

Many are amazed by this puzzle (including me) and my mind is flooded with more requests. I should start making another MindCracker immediately!

Well, this "MindCracker" really blow off my mind. 

Really? Even me, the maker of that cracker still shocked by that amazing puzzle! Again, hail to the great D.T. Brock who made the original version.

I don't understand why the Rook MUST move to e1 ... what is wrong with e2 or e3?

When the pawn captures there's no double check.

This fantastic chess puzzle continues to shocked people...Lincolm and I admitted that it's simply amazing. It blows people's mind!

1. Re2? fxe2!

1. Re3? fxe3!

1. Nxf4+ Nxf4 (forced) 2. Re5#

Re5 is illegal. It has already been solved anyway.

Kxc4. Solution already provided

@Cnacnel, you're right, Re5# is illegal since the previous move puts the white king in check.

@Scottrf, Kxc4 would have been impossible because the Rook is guarded by a white bishop.

Thanks guys, I'll look at the previous solution. 

2... Rxc5 mate.

This is the most difficult 2-mover puzzle i've ever seen!

Thank you guys for visiting this tread.
