Here are my brief comments on some of the numbered positions.

#13
This (Tartakower-Rubinstein/Moscow/1925) also appears in the LCTII Test Suite.

#52
I suggest you play 1...Bf5 and consider White's alternatives to the game
continuation (2.Qxa8 Qd6+ 3.Kc1, etc.). The question then is whether 1...Qd6+ is
just as (or nearly as) good eventually.

#65, and #71
Though these had a place on Dan Corbit's 16-item "disagree list," they do not
appear on the latest one, which has been reduced to 10 items. (Ask Dan the
reasons not me.)

#75
I suggest you play 1.Bxf4 and then wait to see what Junior's evaluation is at
depth=16. It should realise that White is winning at depth=17.
