Here a nice position to try your engines:

[d]b2r2k1/2q3bp/1r4p1/p2nPp2/2pP1P2/2P4P/R1B1NQ1K/2B2R2 b - - 1 31

How does Smyslov win?
Or is there actually a win?

you are joking correct?
I tried a program set at strength=1500 and it solved your position.

Hi Ted.

Your fonts are so smallish, that I can barely see them.

Do I see Komodo 8, depth 19, and 0.28cps white advantage? :?

Stockfish sees only a draw, and does not choose Smyslov's Rb3. I assume Gligorić blundered later.

Kim, I think you should do some mowing, just to relax a bit. :)

I bet black wins this, but I am not responsible for engines' weak play.

A 1500-elo engine would blunder a piece or pawn on the very next move.

Skipper is a 1500-elo engine, and I bet Skipper would not play that perfectly.
