Noteboom variation as played recently
After my previous blog [on a Noteboom-Abrahams variation game], I felt interested on how this opening is played today... and so I knocked on the big game pool door of TWIC. I took a big enough, I think, sample, since Nov 2017, and found some really beautiful games...
Note: As all the games were played by great & active players, I hope that my naive approach will be forgiven...
Firstly some statistics...

And some games of the popular lines, examining mainly the opening options...

Through my study on these games, I've found many positions that could be tactics to solve. I've chosen 25, mainly on the opening and middlegame, with which I've made a homemade puzzle rush 
! I hope it's working properly! Can you solve them in 5 minutes??
