best move: f4-f5 time: 10:01.056 min n/s: 7.226.000 nodes: 4.343.404.721


apparently forgot to edit the hash in the shredder GUI, at any rate, i am quite sure it is the correct move.

Is IvanHoe v70 a new version? Is a 32-bit version available somewhere?

Thanks

yes, it's the latest, though i believe its intended change is merely support of robbobases. could be wrong as i am just now giving it a spin.

best move: f4-f5 time: 10:01.056 min n/s: 7.226.000 nodes: 4.343.404.721


apparently forgot to edit the hash in the shredder GUI, at any rate, i am quite sure it is the correct move.
I think this is too easy/obvious for computers. Some positions simply have one reasonable move, although it might not be so obvious to us humans.
