What do you do if the opponent advances their pawns and attacks your knights before you can complete the operation
Mexican Lawn Mower Gambit

Here's an idea. See how far ur king can get from its home square before its mated.
The maximum would be 7 squares because only the shortest distance can be counted. I think 7 would be near impossible if the opponent is actually trying. But it would be funny to get all the way to maybe e6 or e7 with none of ur other pieces out. Just a pawn and a lonely king.
This gambit will prove to be absolutely, undoubtedly, completely impenetrable. This is because of how your oppenent will react. Most people on the recieving end of the Mexican Lawn Mower have no clue what to do, and will likely waste turns, making poor decisions and blocking themselves in the process.
(This Gambit is also known as the 2 Knights Surrender).
