Nimzo-Indian Defence 5.Nge2

IM Anthony Saidy responded to my latest Chess Training Repertoire. I send it out each Thursday only to those signed up for my email list. I edit his comments slightly:

"Thank you. 5.Nge2 (I always so wrote it, the 5.Ne2 would suffice) was my specialty. If you have computer analysis of a game Onischuk-Browne, with c5 by White and ....e5 by Black, please send it. Of great theoretical importance, IMHO." - Saidy IM

Yes, originally I called that repertoire 5.Ne2, but since the notation spit out as 5.Nge2, I changed it to be consistent. On a side note, one of my favorite chess books from 1974 was "The World of Chess" written by Anthony Saidy and Norman Lessing.

This game Alexander Onischuk and Walter Browne reminds me of the Caro-Kann Defence Panov line where play continues 1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4 Nf6 5.c5 e5. The Panov and Nimzo have various lines that transpose exactly but this does not.
