Hello,
I had CARA (v2.5.10) analyze the 50 games, using SF18 set to 10 secs/move.
The outcomes are rather compliant to Kurt's conclusions.

Alternate move "looked better" means: at shallow depth search (3 to 7 plies). This implies playing the best move was not that easy, and required deep understanding of the position's subtleties! Hence the 'Brilliant' label.
I am rather happy with the ELO estimates based on 50 games, they are pretty spot on.
