A strange line in the Alekhines

I've just finished a live chess game against a fairly high rated opponent. His lack of opening knowledge is inexplicable (he picked the opening) so perhaps he was dared to play the Alekhines defense, or perhaps he thought the game was unrated.

Regardless this game shows how a few opening inaccuracies can build up to a real loss.

Time controls were 25 minutes per side with an incremental time game of 15 seconds. My opponent was mated with over 26 minutes on his clock (this might explain it).

Constructive criticism and analysis are very welcome. Thanks in Advance. Kupov.

Good Game!

Thanks.

I think black understands the basic principles okay, but you are right, locking in that white bishop was a total no-no.  Bishops belong outside the pawn chain, or they are bad.

Well played!

I think on move 12 you can play Bxh7? It's almost thematic if Black cant keep a Knight on f6, a la French defense (well, almost)
