Knight in jeopardy test

Post by ailin »

Hello folks ,
Look at this position minute ,in depth and subtlety.

[d]rnb1kb1N/ppppq1pp/8/8/4n3/8/PPPP1PPP/RNBQKB1R

There is a big claim here : that poor white knight shouldn’t capture black rook in h8 , so in the next move white will loose his queen (true), and WHITE KNIGHT in h8 can’t ESCAPE at all.
at all ?! really? No way ?
How can an author say this in just fifth move of a game ?
Your opinion please..../ and a test for your machines.

Cfish-dev says White is lost---and the knight does not escape:
