STOCKFISH DEV 310314 64BIT [25.0/50][+15/=20/-15] - HOUDINI 4 64BIT [25.0/50][+15/=20/-15]

The greatest discrepancy in evaluation is on move 37:
36. Qd8{-0.10/19 18} Qa6{-2. 43/30 95 (Qxd8)}
I am not sure, but it seems to me that Stockfish's depth-oriented search technique lends itself an advantage in the middle game by searching in areas Houdini seems to miss.

STOCKFISH DEV 050414 64BIT [30.5/60][+17/=27/-16] - HOUDINI 4 64BIT [29.5/60][+16/=27/-17]

Houdini favors the beginning phase of the game, while Stockfish fights for the endgame phase. Houdini somehow forces a draw. As they continue to develop, their evaluation techniques seem to further polarize.

STOCKFISH ENGINE VERSION UPDATE:

DEV 060414 + Syzygy

Author: Ronald de Man
Date: Sun Apr 6 20:48:09 2014 +0200
Timestamp: 1396810089

Merge remote-tracking branch 'upstream/master'

- Rescale UCI scores to PawnValueEg

This is more consistent with what other engines are doing.
Often people thinks that SF's scores are overblown. In the
end, it just boils down to the arbitrary way of rescaling them.

STOCKFISH ENGINE VERSION UPDATE:

DEV 070414 + Syzygy

Author: Ronald de Man
Date: Mon Apr 7 01:15:06 2014 +0200
Timestamp: 1396826106

- Slight cleanup and more efficient order of checking conditions.
- Change in probing behaviour.

If SyzygyProbeLimit is 6 (the default), then:
- 6-piece tables are probed in nodes with remaining depth >= SyzygyProbeDepth;
- 3/4/5-piece tables are probed without depth limit.
If SyzygyProbeLimit is 5, then:
- 6-piece tables are not probed;
- 5-piece tables are probed in nodes with remaining depth >= SyzygyProbeDepth;
- 3/4-piece tables are probed without depth limit.
