Thanks,

My bad, I thought it was within the info given by hitting A8, like position 1 & 4 is.


Cheers,

Al.

About week-1, the first position seemed to be the hardest one but apparently not for Nigel Short. The king walk 1. Kh2 2. Kg3 3. Kf4 all the way to h6 is brilliant.

It seems the solution isn't unique and there's another 2 moves that also win, though.

I got a +10 with Qf4 and never even looked at Kh2 until I found out I got that one wrong and then when I relooked at the position I immediately recognized the move was Kh2 with a king walk from years ago.

I got a +10 with Qf4

c3 and Ne1!? also win.

I didn't check others, but I wonder if it's a position where almost anything wins, so I didn't expect such a position to appear, since it said "find the correct move", I thought the wrong ones were blunders.

yea Black was pretty much dead loss, but Kh2 is the best move ;>)

Already 6 entries are in, boy, you guys are fast, also some of the fast solution times surprised me, hello Vincent

Regarding position-3, the mate in x one - got different numbers and I rewarded the ones I consider correct. It doesn't mean I am correct. I think it's best we analyse the position next thursday till there is a mutual agreement and if needed the ranking will be adjusted.

I'm getting this error right above the line where the FEN is shown:

error: invalid FEN in game 1: invalid fullmove 0 set to 1

Also, I'm already dreaming with the day a position is posted that nobody gets

I'm really slow........ I'm just looking at the positions of the first week and I can't understand position 2. ( engines are not able to explain it to me)

[d] b2r3r/k4p1p/p2q1np1/NppP4/3p1Q2/P4PPB/1PP4P/1K1RR3 w - - 0 1

here the best move is Rxd4 according engines and solution, but it's not a winning move.
The solution talk about Rxd4,cxd4? and then Re7+, but for the engines black reply is wrong and the correct one is Kb6 which give balck a little advantage

What I'm missing?

ure missing nothing, ure absolutely correct ...it was Kasparov vs Topalov from Wijk aan Zee 1999...Topalov took (bravely)with cxd4 and lost while Kasparov missed ra7 and played qc3 instead (which is also winning)
