This Is Why You Should NEVER Use The Alekhine's Defense, Mokele Mbembe

First, black's knight in that silly variation is supposed to go on e6 or a6, not a4.
Second, not taking the a4 knight means that you have to read again the fundamentals (lesson #2 or so).
Third, the way you played Black has a clear advantage after something as simple as 10...g6.
Next time, try refuting the accelerated Kadas defense (1.e4 h5 2.d4 h4).

on move 2 why not d4 followed by f3? seriously you missed a dozen opportunities the capture the knight. alekhine defense isn't even too bad. i've seen some great draws and even a black win now and then.

Yes, 2.d4 is a better move, but still not easy, e.g. on 3...e6 you have to play 4.Bd3 d5 and now something like 5.Nh3!? or 5.h4!? covering the check from h4. But black can also play 3...f6!? when white probably has no more than a slight advantage.

The Alekhine Is Perfectly Fine, This is just a really bad variation. the modern line works out pretty well, along with other variants where the knight goes to ...2Ne6.

I beg your pardon?
Alekhine's Defence has been refuted, surely that is obvious.
For what it's worth, which is pretty much nothing as my expertise on openings is zilch (I'm a beginner), I came to this page by Googling Alekhine Defense\Mokele Mbembe Variation. Reason being, while I was browsing through Chessmaster (the PC programme) openings database of the Alekhine Defense, it got to the Ne4 move, and this is what the annotation said: "Black is gonna die! After 3.d4! f6 4.Bd3 d5 5.f3! Ng56.Bxg5 fxg5 7.f4! (Black's position is a disgusting mess) 7...g6! (the only try)."....so I just had to Google it and see what why it felt so strongly!! Also, the Wiki entry for Alekhine also states that this variation is "very dubious"......so I think the challenge is on for a black player to use this variation - and win!!!

This game does not really demonstrate the true weaknesses of Alekhine's Defense, since you played against a beginner who did very poorly. In my opinion, the best way to refute this provacative opening by Black is to check out the game Short-Timman in 1991, where an outrageous king march by Short crushes Alekhine's Defense.
A very bad variation of the Alekhine's Defense and this game illustrates the dangers it can lead to, including getting both your knights stuck in one corner of the board.
