Test 6 Original by John Nunn
This position is extremely complex. The reason is that the pawns are not yet fixed, and Black can still choose between various possibilities for arranging his pawns. Each arrangement gives rise to a network of corresponding squares, and White is not sure which network is going to arise. In order to understand the play, it is necessary to analyse first the positions in which Black has committed his pawns. The two key positions are given as Z1 (in which Black plays ...f5) and Z2 (in which Black plays ...h5) below.

Re: 83 nice Testpositions (Long and big post).
You're right about a forced mate starting with 1. Re6, but I think the actual mate is a move shorter than you said. As you walk through the line you posted, you'll see it.Uri Blass wrote:<snipped>This is wrong because movei finds Re6 with forced mate scoreGeorge Tsavdaris wrote:

Re: 83 nice Testpositions (Long and big post).
You're right, there's a forced mate with 1. Re6! (but one move shorter than you posted, I think).
I wonder if 1. Re3 can also win...

Re: 83 nice Testpositions (Long and big post).
Could someone post a corrected version of this test pack, please ?
Thanks, Vincent.
Thanks, Vincent.

Would he still believe that current top engines more or less are close to play perfect Chess?
Perhaps in engine-human or engine-engine they are close to it, although i disagree in this too, but in solving testpositions they have many many things to learn more.....

Re: 83 nice Testpositions (Long and big post).
It can. After the 1...Nd1 you proposed, we have the forced moves for black:ardee wrote:You're right, there's a forced mate with 1. Re6! (but one move shorter than you posted, I think).
I wonder if 1. Re3 can also win...
1... Nd1 2. Rd3+ Nf2 3. Rd4 Nxh3 4. Re4+ Nf2 5. Re6 dxe6 6. d7 e5 7. d8N e4 8. Ne6 e3 9. Nf4 e2 10. Nxe2# 1-0
