New idea: V-chess

Classic chess, but with the addition of four new pieces, which are placed on the last line (1 horizontal for white, 8 for black)
                                                    New pieces:

Hawk -  moves like bishop+knight.

Elephant - moves like rook+knight

Prime-minister - moves like bishop+king

Dragon - moves like rook+king

what do you dislike about this variant

I think we have s-chess already

ya we do have s-chess

you forgot something. There are still two pieces, the Prime Minister, and the dragon is not just an S-chess
 

Sound fun

Hi

does your new pieces replace classic pieces. If it’s the case explain which ones are replaced. If not please explain how these new pieces join the game.

the dragon in your game is a Crowned Rook, a known piece 

the same for the Prime-minister it’s the crowned Bishop

The other pieces are Archbishop (BN) and Chancellor (RN).

i tried myself in my games using Queen like pieces. They tend to distord the game especially on the 8x8 board too small for such number of very strong pieces. 

Anyway, it’s  a nice idea worth the trial

They come into play when the classic pieces leave the last line, after which they can be placed on the free field of the last rank
(placing takes a turn)
 

good idea

agreeable; A bit different with s-chess; as we have 4 additional pieces Rather than 2; We Can't gate Right after moving

I saw this. I also thought about a chess variant of my own named Musketeer Chess. The drop mechanism is also different from S-Chess. Your idea was part of C-Chess also knows as camaratta Chess. Not a very well known chess variant but it was invented around late ninetees by Mr Frank Camaratta, a now retired NASA engineer and he is a friend of mine that's why i knew about his game when i invented mine.

For me the most important is that Chess Variants become more and more popular.
