Very good spectacular move!

Nimzo 8 thinks e6 is a hot spot, too. While I was writing this, it analysed in 2
pv mode and preferred Bxe6 (not expecting ...fxe6) and your move Re4 was the 2nd
variant (both evaluated 0.00), but then switched to Nxe6... there seem to be
several paths to the draw. But I like Re4 with it's interference idea combined
with the rook sacs and strong mate threat best.
After a while in 3 pv move, it looks like this (at depth 11):
Analysis by Nimzo 8:
1. = (0.00): 1.Re4 Qxd1+ 2.Kh2 Bxg5 3.Qxg5+ Kh7 4.Bf5+ exf5 5.Qxf5+ Kh6 6.Qf6+
2. = (0.00): 1.f4 Bxg5 2.Qxg5+ Kh7 3.Qh5+
3. = (0.00): 1.Bxe6 Rc6 2.Re4 Qxd1+ 3.Kh2 Bxg5 4.Qxg5+ Kh7 5.Qf5+ Kh8 6.Qf6+
I tried to build a small variation tree for Bxe6, Nxe6 or Re4:
2r2rk1/p3bp2/bp2p2Q/3pP1N1/3P3P/Pn4PB/1Pq2P2/3RR1K1 w - - 0 1
1. Re4 (1. Nxe6 {threats simply Qg7# but also NxRf8} fxe6 2. Bxe6+ Rf7 $13 {
eventually followed by Rc8-f8...}) (1. Bxe6 {
threat is i.e. Be6xd5-e4!, in addition to BxRc8} fxe6 (1... Rc6 2. Re4 Qxd1+ 3.
Kh2 Bxg5 4. Qxg5+ Kh8 5. Rg4 Qxg4 6. Bxg4 $13) 2. Qxe6+ Kh8 3. Qh6+ $11) 1...
Qxd1+ 2. Kh2 Bxg5 3. Qxg5+ $11 *
I think your choice was the best, because 1.Nxe6 is "a bit doubtful" :o) IMO,
and 1.Bxe6 Rc6 seems less clear to me than immediatly Re4.
