Finding 13.Bb5 is easy for every program. But after that move:

[D] rnbq1k1r/1p1nb3/p2pp2p/1B4PQ/4P2B/2N5/PPP3PP/R3K2R b KQ - 0 13

Now what is the correct move for black? All the programs I checked suggest
13...Kg7, giving black a good advantage. But that is the wrong move which will
lead into a loss (the three Argentinians played 13...Kg7 and lost the game in
the same manner).

As Paul Keres showed, the only correct move is 13...Rh7 which will lead into a
draw. Now, which engine can find 13...Rh7 ?
