Sac gone wrong?

    Hey guys... I'm a 1400-1500 rated player in blitz and I love attacking and sacrificing pieces, even randomly. In this game however I sacrificed my knight for an attempt to mate the castled king on the 'h' file. But the attack ended in a horrible disaster.. any ideas on how I could've checkmated?

    16. Rxh4 seems better and it looks like black will have to give up his queen for the rook.

    In addition to 16. Rxh4 for being much better, I also think 15.Kf1 was weak. Why not 15.Kd1? Black still has to play Bh4, and then you simply take the knight on c2 with the king.

    Surely Rxh4 will still be stronger? But the knight wont have an escape square on c2 if Nxa1.

    Kxc2 is a zwischenzug. White still forces black to have to sac on the rook with the queen, only with Qc2, white ensures the knight is lost additionally in the process. So it would be something like 15.Kd1 Bh4 16.Kxc2 b5 (black has no good moves) 17.Rxh4 Qxh4 18.Bxf7+ Rxf7 19.Qxh4

    16... g5 doesn't help at all? Was wary of giving away a tempo, but I guess it doesn't matter?

    @Scottrf and @FirebrandX,

    yeah.. that was my blunder, I should've played Rxh4. But I didn't play Kd1 for two reasons, I was distracted and I didn't want to lose momentum on the attack on the castled king by attacking the knight. That knight was useless anyways in that area anyways.

    @Fulliautomatix

    11.Bd2 was the sac to clear the 'h' file.

    Your attack doesn't force mate in that position, which means you'd have to play for the material advantage in the endgame. As such, picking off the knight for free is essential in making your task all that much easier instead of letting the knight snap off your other rook.

    16...g5 fails to 17.Qg6+! Kh8 18.Qh6+ Kg8 19.Rxh4 gxh4 20.Bg5 and black is completely screwed.

    Ooh... didn't see that either.. :)

    Btw.. what's a zwischenzug?

    It's a chess term for "in between move", which means an advantageous move you can squeeze in for free in a tactical sequence.

    here's another one..

    What on earth am I doing wrong and what can I do to correct my technique? (As in for all such games and not this one)

    At one moment I'm ahead in the game and the next I end up in with a losing endgame...

    Two pieces for a rook and pawn is bad in that position (move 8).

    As for what happened, you set up a discovery on your own queen.

    Yes, "zwischen" means "in between", "Zug" means "move" and in German it's allowed to connect words to create new nouns.

    Yeah he broke one of the rules of thumb that trading the two pieces for the rook and pawn is bad in the opening because you lose two developed pieces and fall behind as a result. It's better to do the trade later near the endgame if it comes up as possible.

    Also, I don't understand why he played 18.d4. There were many different better moves. Everything from a swindle attempt like 18.a4, to simple moves like 18.Be3 or 18.Bf4 seemed better than d4.
