Bad opening leading to defeat?

I have challenged my friend to a round of chess. I did my usual opening, but I found my king's side literally demolished. What went wrong? Can you suggest a better opening or moves for Black to be in a more favorable situation?

You take the pawn on d4.

You were doing fine until h5 followed by Rh6.  Both of those almost never being good choices of moves.

f6 is a super-bad way to guard the e pawn.  It opens up a diagonal to your king.  See damiano's defence.  White could have exchanged pawns on e5 then Qh5+ and things get really hairy for black.  g3 to block the check looses the rook to Qe5+ for example. So you must move your king and can no longer castle...  Capturing on e4 is much better.

So to answer you question, yes this is a weak opening that cost you the game.  You weakened it by moving you king side pawns.  f6 weakens your kingside as does h5.  By the way, h5 is a bad way to develop your rook.  Castling is much better because it moves your king to safety and moves your rook to a central file where it can help control the center.

AS far as other moves you could have played...

d6 is bad because after exchanging pawns on e5, Qxd8.  Kxd8 is forced and now you can no longer castle. Nc6 seems bad because of d5 kick th knight and gives white an edge is space.  So since defending the pawn is not an option, exchange it with whites d pawn!  White must recapture with queen or go down a pawn, and you can devolop while attacking the queen, getting several "free moves."  Also, whites e pawn is also somewhat weaker now, since its partner is gone.  It can only be defended by peices or with the f pawn, and we saw how well that worked for you.  This is good compensation for the small edge in space that white has in the middle.

Yes f6 is the weak move, but it was salvageable until you hung your rook..

I don't think your second move was very good. It's playable, but a better way to defend the pawn is 2. ... d6. The problem with 2. ... f6 is that exposes your king. 2. ... Nc6 is also probably better. But probably the best move is to take the pawn with 2. ... ed:

I agree that 4. Nge7 is probably not good. It stops your bishop from getting out on f8. This makes it hard for you to castle. It would be natural to play 4. ... Nf6, but you can't do that because your second move deprived your knight of its best square (another reason why your second move was not very good).

With 5. ... h5 and then 6. ... Rh6 you are verging on suicidal. Beginners often like to develop their rooks early by moving a pawn on the edge of the board and moving the rook forward. This is usually a terrible mistake for too many reasons to list here. However, in this case white can simply take the rook with the bishop and win the exchange (and leaving your kingside defence in tatters).

After 8. ... ed: white has mate in three with 9. Qxh5+ Ng6 10. Qxg6 Ke7 11. Nf5# (mate). Instead 8. ... d6 would have kept you handing on but about 3 points down.

Play the game through again and just focus on the c4-g8 and h4-e8 diagonals. You generate chronic white-square weaknesses by exposing these diagonals with injudicious pawn advances around your king.

Thanks for sharing the game though. Hope you found my comments useful. I have to say that white played very very well and exploited your weaknesses very efficiently.

There is nothing wrong with the start of ur opening, your problem started at move 4. where you blocked in your darksquared bishop with your knight and after that everything else went wrong. It seems to me that you have no knowlege of the basic ideas behind the chess opening, i would suggest reading a few of the articles on chess.com and a beginners chess book to try and grasp these concepts. As well as concepts of material seeing as you gave away both a rook on move six....

i think its start with the f6

That is your usual opening?  Try the sicilian, caro kahn, pirc, french, or even the st. george, they are all more stable than whatever that was.

Well, sir, you have attempted the Woodchuck opening which is another of the discredited rodent openings. This is when the rook (or, woodchuck) pops out of his hole (h8-h6), and is then snapped up by the bishop, losing the exchange, damaging the king side pawn structure, and providing no compensation at all. You have seen the consequences so now know to look elsewhere for an opening that suits you.

As stated, exd4 is the best second move. After Qxd4 Nc6 the queen will move again and you will develop a second piece, while white only has the Queen in play. h5 is the most difficult to understand move, maybe it would help if you could annonate the reasons behind h5 and Rh6. Many of the early pawn moves came at the expense of important piece development.

You should have a look at what would happen if he took your pawn on e5 straight away in the game explorer...

It's not pretty, but it should discourage you from playing f6 again :)

Damiano's defense... if you want to reinforce the e5 pawn with another pawn, d6 is a better choice, opening up the file for your c8 bishop.

Then, getting the rook out early... not so good. Rooks are more designed for open areas, not a cluttered opening board.

dont just let him capture your rook like that

Damiano's defense... don't play it.
