Go up one level in this thread


So that is another reason for 4.Ng1-f3, saves a lot of work! I believe that is
something of a Hanham set-up in the Philidor? So do you think 4.f2-f4 would be
the stronger move? I don't know if Rebel would handle that very well, maybe that
would best be played by gambitting Tigers.

This is Q5T analysis after
