Playing a lot of blitz online, from time to time I meet quite strong players who regularly use very dubious lines that can have some shock or practical value in blitz or bullet chess, such as these, as White:

1.e4 e5 2.Bc4 Nf6 3.Bxf7+

Or, as Black:

1.e4 e5 2.Nf3 Bc5 3.Nxe5 Nc6

1.e4 e5 2.Nf3 d6 3.d4 Bg4 4.dxe5 d6

1.e4 d5 2.exd5 Qxd5 3.Nc3 Qe6+ with Qg6 and an early Nc6-b4 attack

I was wondering if all of this means that some players have their private analysis of some (objectively bad) lines for use in speed chess.

Are you aware of other similar lines? As you can see, I don't mean Grob's Gambit or Cochrane's Gambit, but the very bad lines...

    The Halloween gambit maybe? – Glorfindel Nov 6 '17 at 20:03
  • Yes, I meant something like the Halloween. But perhaps even more unknown and unsound, as you can see from the samples... – A. N. Other Nov 6 '17 at 20:04

    d4 g6 Bh6 brought me couple of victories in 1+0. You either win some time or the whole kingside. – hoacin Nov 6 '17 at 20:40

    I lost to many many games from your line. @hoacin. I don't do ...g6 anymore. – SmallChess Nov 7 '17 at 1:28

    1.c4 b5?! White often pre-moves the second move of Nc3 or g3 which just drops the c-pawn. – Ywapom Nov 7 '17 at 19:31

In bullet chess (1 min or less), you basically don't have time for thinking and will pre-move or make moves instantaneously often making assumptions about your opponent's moves. In such situation playing the best moves becomes less important; basically you just need to move fast without blundering too much. Playing chess at such short times becomes more about bluffing and less about thinking.

The practical value of dubious lines/moves can be two-fold:

  • your opponent has to think (=losing valuable time) to refute the move
  • your opponent plays a standard (pre-move) which is not the best in this situation

Due to the limited time it is difficult to refute such dubious lines even if you lose a minor piece. So there is little risk involved.

I doubt there is much private analysis involved. I also doubt there is much value in trying this at longer times (3 min or more).


There are tons of first 4 moves that involve ridiculously unsound sacrifices, but most of these usually involve Bxf7+ and have no place in opening theory.

These 'openings' are largely based on a gross overvaluation of castling rights: you can just slowly castle by hand, especially since the attacker usually has no other pieces developed yet (e.g. after 1.e4 e5 2.Bc4 Nf6 3.Bxf7+ Kxf7, the only developed piece is black's); if the defender loses, it's a result of being outplayed, and is no fault of the opening.

Therefore, such lines are hardly worth studying to defend against, and even worse to learn to use. Just fall back to basic principles (develop your pieces, do not play h6 without thinking it through...) when facing these, and you will emerge with a long-term advantage.


Yes, there are quite a few dubious lines one could try out when there is nothing much at stake.
1.d4 e5 2.dxe5 f6 comes to mind.

There was a book on blitz openings, but those variations are "fundamentally sound" according to the reviewer.
