In Crazyhouse, promoted pawns should be marked

In Crazyhouse, when you promote a pawn, the piece that you promote to should be marked somehow so that players know it will revert to a pawn when captured. Crazyhouse shouldn't be a memory game. All relevant information should be visible at all times.

You are right but how would you implement this suggestion? Until now all variants get along with the usual chess set, for your idea it would require new queens, rocks, bishops, knights for all piece sets.

Yeah I've thought about this idea as well, @Veletas. It's a good suggestion.

Just coloring the square under the piece can be enough

It's of course a bug, information is missing. Correct play is very difficult if you have to remember which piece is promoted and which not. It becomes a memory game as Veletas said. But there is no need for extra pieces. Scidb has used a very nice solution for some time already.

There's no screenshot of it though.

@variant maybe describe it...

I don't think this should be implemented, as it isn't much to remember and if you ever play crazyhouse over the board you have to remember it there.

If all relevant information should be posted at all times than how about an opening book always be available. Where does it end?

Sorry, I had a link but it didn't seem to work, so I removed it. You can see it by installing scidb - a great chess database program for linux. A good solution is a suitably coloured disc (orange/yellow/gold looks nice) under the promoted piece, close to what dstark suggested.

EnergyFlow, I mean all information about the game state.

Of course, you could say that, by the same token, the king should be marked in some way as long as it retains its right to castle. And maybe it should. The right to capture en passant doesn't need to be marked because your opponent's last move already is.

@isaacly, you could simply mark promoted pieces with a red belt around their waist. Most pieces already have such belts outlined (except knights).
