Simultaneous Chess

With computer technology, we could have a "chess" where both sides log in their moves and the moves are made simultaneously.  Neither wouldn't know what the other player is moving until the end of the turn.

As for captures, the attacking piece could be "sticky",meaning if, on the next move, the victim of the attack would be able to recapture "first" before the opponent's move is enacted. 

We are working on a game that might interest you. It's called Chezz and it's currently being soft launched on mobile platforms.

In Chezz, both players can play any pieces at any time but once you move a piece, you cannot move that specific one again until a short timer is completed. Check it out, let us know what you think! 

Too many pieces can move at once. Great for computer multitasking though.

I would like a hybrid between Real-Time Strategy and Turn-Based tactics.

A simple way of playing this game is that both players decide their move previously and simultaneously, but White moves first and Black follows.

Since White moves first it will never make an illegal move, but Black could.

The first illegal move made by black is canceled. Simultaneously both players will decide their next move again, but Black moves first this time, White follows.

Until White makes it's first illegal move (which will be canceled), then both players decide their next move, but White moves first and Black follows.

Rinse and repeat.

All games are legal FIDE Chess games.

That makes sense.

Yes

Can 't one player make a move which would be illegal in the current position but legal when some predictable opponent's move happens?
