Any engine see a draw?

[David Dahlem]

In a recent game between two so-called derivatives, this position was reached.

[d]6k1/8/8/8/q5p1/3p2P1/3N1R2/6K1 b - - 1 45

The game ended in a draw. Stockfish 1.7.1 gives a big score for Black:

38 06:56 531.691.157 1.275.947 -5.05 Qa4a1+ Kg1g2 Qa1c1 Nd2f1 Kg8g7 Kg2g1 Kg7g6 Kg1g2 Qc1c2 Nf1d2 Qc2c3 Kg2h2 Qc3c6 Kh2g1 Kg6g5 Kg1h2 Qc6d5 Kh2g1 Qd5d4 Kg1g2 Kg5g6 Rf2f4 Qd4b2 Rf4f2 Qb2e5 Kg2h2 Qe5e1 Kh2g2 Kg6g5 Nd2f1 Qe1e4+ Kg2g1 Qe4e5 Rf2d2 Qe5d4+ Kg1g2 Qd4d5+ Kg2g1 Qd5c5+ Kg1h1 Qc5c6+ Kh1h2 Qc6f6 Kh2g2 Qf6f3+ Kg2g1

Is there any engine that will see that Black can't make progress?

Is there any engine that will see that Black can't make progress?

Perhaps he can. The fact that derivative's game was a draw is irrelevant.

This is a dead draw position but with the black king on a8 white loses.
It would be nice to see an engine which would recognise a fortress or a blockade in the endgame. Is there any?
