Ng5 Rf8 then what?

a4 is correct too, though maybe Nxf7 is better

Don't have the EPD handy right now.

Nc5 looks fine, but I have some assymetry problems here

Why would it be better than Nxf5?

after Rc3 I get

depth=8 +2.83 1. ... Kf7 2. Nxf5 Qg6 3. Nxe7 Qxc2+ 4. Rxc2 Kxe7 5. f5 Rh6 6. f6+
Kd7 7. Rc5 Re8 8. Rfc3 Re6 9. f7 <HT>

note it plays Nxf5 anyway. An immediate Nxf5 goes to +4
