Strange move ?

Can someone please take a look on my game with ELROY and eksplain to me his last move ?

 

u mean en passant?

I dont know, but I didnt understand how he could move that way ?

Passant, what is that ?

I assume you are referring to 38. .. g5  39. hxg6.  En passant is a special capture made immediately after a player moves a pawn two squares forward from its starting position, and an opposing pawn could have captured it as if it had only moved one square forward. In this situation, the opposing pawn may, on the immediately subsequent move, capture the pawn as if taking it "as it passes" through the first square; the resulting position would then be the same as if the pawn had only moved one square forward and the opposing pawn had captured normally. The En passant capture must be done on the very next turn, or the right to do so is lost.  Typically the notation would be 39. hxg6 e.p.

Thank you very match, it was good explained.

I didnt know that move and thought I have moved too short forward.

Thanks again :-)
