I'm already on my own & at a crossroad. Had this been a correspondence game, I would have taken a few days here to check my references & compare lines.
Alas, in OTB play, there's no luxury & the decision musy be made in minutes.
7...Nxc5
[In Play The Nimzo-Indian (Permagon, 1985), Gligoric says this "pushes White's Q back to a better square" (it does & also loses time) and recommends 7...Nxd2
8.Nxd2
Bxc5
with "a satisfactory and flexible position.)
However, Alekhine & Tartakower preferred the text. They said NxB would give White "strong pressure on the open file" & "chances on the d-file."]

Longest think by White - 4 minutes for 26.Bf3.
Longest think by Black - 9 minutes for 22...Bxf3!
Not a good way to start the event but I'm just a half-point back & there are 12 weeks (possibly 24 games!) left.
