Hi there,
hard to say!
At the moment Houdini 2.0c x64 is still running in SWCR. After around 300 games + 18 to version 1.5, after 254 + 16. I think with more games ELO will be higher. Main problem is that the results from the first and latest places in a ratinglist are not exactly enough. I think what the programmer gave on information, +30 ELO to 1.5, could be right. I made some databases analyzes after the first 250 games. In all points, early & late middlegames, early & late endgame, tactics, king safty ... Houdini 2.0c x64 is better as the predecessor 1.5. In much of the statistics clear better. The reason I think that it could be more as +16. Let us wait of more SWCR games.
I don't test version 2.0b (will not test so many versions of the same engines) but only in 4-5 games I saw that Houdini have problems in tactics in middlegames. The only point we can search weeknesses in Houdini. In all other points I think Houdini 2.0c x64 is clear in front. Perhaps in the early endgame Komodo 3.0 is a tick better, try more to used each little advantage for win a game. In tactics early middlegame Stockfish 2.1.1 x64 and Spark 1.0 x64 are abit better in my statistics. But in all other points Houdini 2.0c is now on place 1 after my statistics.
So, after my opinion:
Hard to say that an other version as 2.0c is better in middlegames. Because 10-15 ELO here without to have more strong opponents isn't clearly to see.
Indeed, interesting are games vs. Chiron 1.1 x64 and Junior 12.5.0.3 x64. The games Houdini 2.0c x64 lost here are great to see which "little" problems the number 1 have.
