Thanks for it. 2 positions are useless.
r2qr1k1/ppp2pBN/3p1Pp1/2n2b1p/7Q/1P4P1/P5P1/1R4K1 w - - bm Qg5;

and
r2qr1k1/pppb1pBN/3p1Pp1/2n2R1p/7Q/1P4P1/P5P1/1R4K1 b - - bm Re2;


Qg5 is too easy and Re2 gives nothing.

But what about this one? Does Rf4 draw as most engines suggest this move instantly?
