My impression of what LZ has learned so far tactically (more than Alphago zero learned in 3 hours) 1. LZ likes to take opponent dead stones out of the board (just like human beginner)
2. Likes to cut, or even cross-cut opponent group.
3. Tries to make own group survive by escaping, or attacking surrounding opponent stones.
4. Knows when to resign (not filling up all the empty spots).
