Can't figure out how to show a promotion to a Knight in pgn.
The following is the way it is supposed to look in the end.
I figured it out. Here we have 2 bishops + 3 knights = 5 pieces.
The King and pawns do not count in the piece count, IMO.
(See previos post for the beginnig position.)

Then RJ shows a four piece mate. 🙂
(RJ the c6 Bishop does not figure in the final checkmate.)
It's harder than it sounds to set up a plausible looking 5 piece mate.
It appears the most I have is four piece mates.

But it does not count. Remove the c7 Rook and it's still mate.
Of course I have 2,345 games where I sacced 5 pieces.....and lost!
Good Thread 135705 reaquainted with this wee gem.
Black to play and mate in 6 moves.
clue?: Keep checking. (always look at the forcing moves first) 5 checks then checkmate.
That is what to go for in your games. Not five piece mates.
Five checks and a mate!
You don't need 5 pieces. Sometimes one will do.

Originally posted by SwissGambitIf we all played perfect chess and saw every checkmate, no one will ever get Checkmated. So stop being so asinine. We must assume he overlooked the underpromotion idea that would mate him in this example. These are not grandmasters playing in my example. Okay.
Black would play ...RxP rather than get mated; Bc6 or not. 😕
Originally posted by greenpawn34I showed a 5-piece checkmate, numbnuts! I guess one must be rated 2400+ on RHP to count pieces, as somebody else pointed out earlier. The final mating position is what we are referring to here. Knights and bishops are called pieces.

There are 2 bishops and 3 knights, so that equals 5 pieces. Of course, there is only one piece giving checkmate and it does not matter that the c6 bishop is not doing anything at this point, there ar still five pieces there.
Originally posted by SwissGambitThat is a 7-piece checkmate. That is, 3 minor pieces, and 4 major pieces.

I had 5 minor pieces in my example checkmate.
Originally posted by greenpawn34If the black king had moved to e5 instead of g5 it would have taken you one more move to checkmate. Just saying.

I given RJ up as a lost cause. But just in case there are any novice players
reading this are getting confused.
Let us look at Swiss G's example.
Final Position.
That is a four piece mate. (a rather unique setting by the way.)
Only four pieces are actually taking part in the final checkmate.
The Rook on d1, the Bishop on a6 and the Knight on h3 are playing
no part at all in the checkmate, they should not be counted.
The fact they are still on the board when checkmate was delivered matters not.
That is a four piece mate.
However It is what I would call kill an over kill.
You can remove the g5 Bishop and it would still be mate.
Put back the Bishop on g5 and you can also remove the f8 Rook.
Technically that is NOT checkmate. (why?)
Another thing that is unique about the final position.
The Black King is being checked by two Rooks at the same time.
That is not something you see everyday.

White to move and mate in two.

1. Nxf7 Kg7 2. dxe8N {CHECKMATE} [/pgn]
Count them pieces - 2 bishops + 3 Knights = 5 pieces.
(See next diagram - the pawn is supposed to promote to a Knight.)
That is definitely a 4 piece checkmate. The bishop is protecting a piece that cannot be taken by the King. The mate would still work without it...
One 😴 wasn't enough

Originally posted by greenpawn34It can't be checkmate because there is no legal way to have arrived at that position. The other positions hold because a pawn promoting from e7 to f8 would give the discovered check and remove the blocking black piece it has just taken. Underpromoting to a castle is cheeky, but very much Swissgambit style 🙂
