Why it works
White has given a knight for nothing but the wreck of the black king's shelter; 8.Ne5 renews the threat against the weak e6-pawn. 8...Bf7 is the move most players find, and the stronger the player the more likely they are to find it: 31% under 1200, 71% at 2000. It defends e6 and offers the trade of the bad bishop. What it also does is put the bishop on the square White wants: 9.Bc4 hits e6 a second time and ties the bishop to its defence, 9...Nd7 develops, and 10.Nxf7 takes the bishop off — the knight on e5 had been eyeing f7 all along, and 10...Kxf7 walks into Bxe6+. Black keeps nominal material and White keeps the attack — 64% for White across 16,000 games.
Refutation
8...Be4 is the rare alternative that scores best for Black, though White still holds 58% — this position is uncomfortable however Black plays it. The honest summary: the Martian Gambit is not sound, but after 7.Ne6 the defence has to be found move by move with no king safety, and that is a task few players solve in blitz.
