Thank you for that.
I gleaned over the test suite with analysis and diagrams on the web (http://privat.bahnhof.se/wb432434/pos.htm
), these are all open positions, except for #14. That means that in the remaining 15 positions stockfish should be irrefutable by humans. I checked that conjecture and indeed in 8(!) out of 15 cases the commentators got it wrong or backwards. How many points would you give for that??
I personally enjoyed this rebuttal the most:
[d]1rN1r1k1/1pq2pp1/2p1nn1p/p2p1B2/3P4/4P2P/PPQ1NPP1/2R2RK1 b - - 0 1
1..Rxbc8 2.Nf4 (allegedly the refutation) Nxf4! 3.Bxc8 Nxg2!
In #14 the alleged best move 1.Nb1, played by Kasparov, is neutralized outright by 1..b5 and black is well.
[d]r3r1k1/ppqbbpp1/2pp1nnp/3Pp3/2P1P3/5N1P/PPBN1PP1/R1BQR1K1 w - - 0 1
In #16 after 34.Qxc5 (stockfish) resigning is an option.
[d]2r2k2/5p2/2Bp1b1r/2qPp1pp/PpN1P3/1P2Q3/5PPP/4R1K1 w - - 0 1
Interestingly with the help of stockfish you might save even this position against a strong human master. Since after the 34. Rc1(?) Qxe3 35.Nxe3(?!) Bd8 36.Rc4(?!) Ba5 37.Nc2(?!) g4 38.Nxb4(??) it follows 38...Rb8 39.Bb5 Bxb4 40. Rxb4 f5! and white is only minimal better (stockfish).
Never trust your test suite.
