I am thinking about replacing that position with this one:

[D] rn2r1k1/p4pn1/1p2p3/qPppP1Q1/3P4/2P2N2/2P2PPP/1R3RK1 w - - bm Nh4; c0 "Oechslein-Oppermann, VWC9/pr 20 ICCF 2016";

This is tricky but not quite as tricky as the one you have been pounding on.

These two are not new to this version of the test suite. They are known to be quite difficult but I believe the solutions are both correct. They were probably discussed here in the forum before.

Notable is this position (#197), which is moderately difficult (c4 is good, but g4 is better and was actually played in the game):

I replaced positions #194 and #197. Latest version here:

I am going to make this the official version unless there is some other problem discovered in the next week or so.
