100 games at 3 min + 1 means nothing, certainly not +45 elo.

An interesting game. The Alekhine-Chatard Attack is my favorite line against Classical French.

Houdini's first move out of the book (8...Qh6) was already sub-optimal. On my end H6.02 finds 8...Qe7 at depth 26, switches to 8...Qh4 at d=27 and goes back to 8...Qe7 @d=33. So at LTC Houdini would find a better move than 8...Qh6.

Although SF may hold an edge over Houdini in head-to-head matches at any time control, on rating lists (where the games against the top engines are only a part of the picture) it's liable to perform somewhat worse as Houdini (and Komodo) are a lot more ruthless with second-tiers than Drawfish.

I agree. Very little meaning.
