I think that almost all or all the positions are tactical(some may be found for
positional reasons but after enough time you can also see winning material).

The positions were supposed to be tactical and the fact that a small part may be
solved for positional reason is only a disadvantage.

position 2 is a clear tactical win and movei can show a score of more than +4
after a long search(it is not easy to see it and it is possible that Tinker need
more than 5 minutes to see decisive win but I expect it to find it after enough
time).

I suggest that you give the positions more time.

you can give them 5 minutes per position and I expect you to find that more than
40 positions are tactical.
