1. e4 e6 {A strange game. White offers to play a gambit, Black declines with a
dubious side-line, and White (should) have a winning position by move 15.

1. c4 Nf6 {A very lucky escape: White mishandles the early middlegame in an
anti-Grunfeld and is clearly worse. Black trades down to a winning Rook ending,

the win.} 2. Nf3 g6 3. Nc3 {a popular anti-Grunfeld line,} d5 {but Black
