ProDeo Q3 finds Rxg6 in 1 second. All other engines i tried could not find it, although after forcing this move, they like it.

Thanks John. Strange, i tried all these engines, and they all show Rf1 with a 0.00 score for a very long time.

Re: Test Position: Rxg6
Mmmm 
Maybe there is some bug or maybe there is something fishy about the position but Rainbow Serpent thinks it is a dead draw for some reason, and I left it running to complete even plydepth 21, and it was still a draw. Rxg6 becomes first choice again at plydepth 18. 21 ply took very long with only 128 Mb TT. The 2. Nf4 continuation is seen early but for some reason the 8 ply result with Nf4+ is negative and then it never comes back...
Have not checked the PV or anything.
