Houdini 4 is lucky and ends up in RB vs NB on opposite-color which tend to be considerable more drawish than same-colored bishop endgame.

I noticed that according to the manual Mr. Houdart has reinstated the learning capability. That was my favorite thing about Houdini. I am not totally sure it will come with Houdini 6 though because a few months ago he said it would not be included. If he did put it back in, I surmise it was because of what Alpha Zero did.

Houdini 6 Chess Engine User's Manual:
Position Learning

With Position Learning Houdini will remember advantageous principal variations it has analyzed by storing them in a learning disk file, for reuse in later games or analysis. The feature is completely transparent to the user, once Learning is enabled the data will be saved and loaded automatically.
