Hello Joseph, off topic but by any chance a chessboard like this here in
Wollongong? There is a fellow in the background with a beard that could well be
an East-european but then again, there must be many such chessboards in
Australia, and your University also has locations in Sydney? Anyway, I thought
they were nice pictures!

On the subject of Gambits, I'm trying to collect some material on the King's
Gambit and see what the computers play. So far I've found one line where I
thought Spike may have found a small alternative move in a sideline, but it's
not really a big TN as it is in not a very promising line for Black to begin
with even with better moves. The computer plays 12..Rg8 at the end of the
analysis, in the system with 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.h4 g4 5.Ne5 Nc6?!, in
the position from the diagram:
