 By Ralph  Betza. Overprotection Chess. If an attacked piece is more often defended than it is attacked, it gains extra powers. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

You have trapped me and won the game of game-making!

You suggested recursive, and I said 'sure, okay', and then you hoisteded me
with me own petard by pointing out a most ingenious paradox, more ingenious
than Doctors Einstein and Schweitzer. I am bereft, like an apprentice to

Where can I find an mp3 of busy editorial beavers whistling the 'Happy
Editor' song as they undo a previous change?

A Pawn or piece must be attacked in order to be overprotected. I said that,

'and dynamic' ... 'where checkmating the opponent could also checkmate
you!' means that the enemy K is defended several times (but of course not
attacked) so that when you attack the enemy K it becomes overprotected and
gives check to your nearby King. I could have made that clearer, right? But
you're correct, even the closest reading of this doesn't really say whether
it's recursive. Yes, why not recursive, gosh darn it and gosh darn it

If you could overprotect an unattacked piece, this would 'merely' be a new
(and perhaps an excellent) form of Relay Chess.

So, should add a line that the powers gained by an overprotected piece can
be used to overprotect another piece.

Should add a line 'therefore you can destroy your opponent's overprotection
by moving your attacker away'.

And should add the explanation of how giving check[mate] can check[mate]

Better now?

This looks like fun! I particularly like that once you overprotect a Pawn by two (easy enough -- just take an unattacked Pawn and give it two supporters), suddenly it captures forward and to the side. <p> I find myself wondering if overprotection is calculated recursively. That is, when determining overprotection, is overprotection taken into account? <p> Consider the following: <blockquote> White Pawns at <b>a3</b>, <b>b4</b> and <b>c3</b>; <p> Black Pawns at <b>a6</b>, <b>b5</b> and <b>c6</b>. </blockquote> Assume white's move. Can the white Pawn on <b>b4</b> capture the black Pawn on <b>b5</b>? If you apply white's Wazir capture first, then it can (since it is overprotected by two, black not having a Wazir capture as it is only overprotected by one), if you apply black's Wazir capture first, it can not (since then the white Pawn will only be overprotected by one). Curious, no?
