Ahh, did it :) okey dokie, this is a position at move 23..(x) R4, SF, at H all want to move Nde5 thus allowing 24.h4 which is a killer and wins in all variations that I could find. I resigned with black pieces. My blunder was probably earlier. I have not gone over this game, but I will (have 20+ games going). After R4 makes 23..Nde5 I looked at 24. h4 but not too seriously as I was concerned with g5 as was all of the mentioned engines. Too me a very informative game that I will not forget.

First      -  > no castling for either side
Second -  > no en passant field
0   > no Halfmove clock
23 > Full move number

A FEN description has six fields.

3. KQkq
4. -
5. 0
6. 1
