agChess -- an agressive chess variant

[hgm]

No, the piece you describe (Q+N) is known as Amazon. It is indeed worth a lot more than a Queen. In fact, a preliminary measurement showed it to be exactly wrth as much as a queen plus a Knight (1250 cP). There is apparently little synergy between the Queen and Knight moves.

A Nightrider is a Knight that can make more steps in the same direction (until it encounters something). So a Nightrider on b2 could go to c4 (like N), but also to d6 (ic c4 was empty) and e8 (if c4 and d6 were empty). A Nightrider is to a Knight what a Queen is to a King. It is worth about half a Pawn more than a Rook.

In Nightrider Chess, the Knights are replaced by Nightriders. I did not find any description of this variant too, not even on chessvariants.com but Dabbaba seems to play it (it knows all kinds of variants with altered Knights). The Nightrider is a piece that quite often appears in fairy checkmate problems, though, which makes it one of the best-known common fairy pieces.

I have a question about Night rider Chess. If I read the description correctly, a Knight can move as a Knight, it can also move like a rook and a bishop. So in Nightrider chess, a Night/nightrider is a more valuable piece than a queen?? I try to google Nightrider chess, but the descriptions I got were too confusing.

Hi Tony,

The Knightrider moves exactly like standard knight, but can, (as long as it lands on no other occupied square, except when capturing) go from one edge of the board to the other (slider+leaper) in one move. It's piece value is around 600. Dabbaba values it at 625, so worth a bit more than a rook.

Jim.

My taste is for seemingly minimal deviations from the classical chess (or else it's not really a variant anymore).

Heh, I'd like to call them "metavariants"

When I was a kid I created several chess variants, then, when I got internet, I discovered that all of them already existed, though my implementation was different (for example, in my crazyhouse variant, pawns could be dropped anywhere in the board, promoting upon drop on the last rank, pieces could be captured and dropped on the same turn, etc.)

In fact this seems about the only situation in which I would consider capturing my own pieces. So in practical play, the new rule might not cause any difference whatsoever.

It will probably not occur often, but there can be many reasons for capturing your own piece.

fx
A white pawn on b7 is blocked by a black knight. White can play a knight to c8 and play b7xc8Q.

Bb2,Qc3,Pg7/Kg8 - Qxg7+ could be a mating move (depending on all the other pieces on the board)

Ra1,Bf1,Pe2,Pg2 - white wants his rook to the 8.th row.
It can be done with Rxf1, Rf8 or Bxe2, Rh1, Rh8 or Bxg2, Rg1, Bh3, Rg8 (depending on all the other pieces on the board)

Kh1,Qa8,Pg2/Qg3,Ng4 - Qxg2 prevents the mate.
