That's cool you noticed my common defense is based on the Sicilian. Can I call it the Vickilian?

I did a study to try to learn if the queen can be used for an effective flank attack. I'm not sure how to study every possible combination, but it seems like the queen by itself can't do much in the opening.
Same as in normal chess, the queen has too much value, so cannot be used in early exchanges. From the starting position it takes at least three moves (or 1 P + 2 Q moves) to get behind the opponent's army. But the defense is faster than the attack, giving the defender "free" plies to also develop other pieces.
However, in the 4-player version, it appears McGoohan and hitthepin have used a flank attack for some advantage. (But the game is in progress, so can't comment on it more now).
For now, I feel that queen-only flank attacks in normal 2-player is dubious. So I guess it doesn't get named after anyone. Unless we find a reckless or daring player.


PixelByPixel’s opening was first seen in his game with @captaintugwash, and featured the interesting chancellor maneuver 2. C(11,2).

Interestingly, this also when the HTP attack was first played, with the follow up of 2. (4,4) :)

No problem. That's why tomato started this thread. I also realized my diagram above has some missing lines. Like Q(8,11). It harasses the king, but is probably still pointless because the king can easily jump aside.

Just like the normal Reti in classical chess, 1. N(6,3) was designed to be very flexible.
Usually, I intend to play (4,4) and (5,3) at some point in the game. This ensures that White gets at least a piece of the center. This usually baddens the dark-squares bishop, so I move it backwards, usually to (8,-4). There it can jump outside the pawn chain and also defend the weak outside hawk pawn by going to (1,-11).
If Black plays (4,5) at some point, then I can play for a (3,4) advance, much like in a queen’s pawn game in classical.
Some long term possible ideas include control the 5-file (after (5,4), the center file is ripe for opening) and/or persistent queenside pressure, where the pawns are unblocked and very flexible.
These are just some ideas when I came up with 1. N(6,3). Hope this helps whoever plays it!

I look forward to being white so I can claim the Tugwash attack with a hawk move, probably the kingside one.
ANd I really look forward to the "Four Hawks" game where both players develop the hawks before moving anything else.
