Stylish victory or stylish fail

What is aim of chess game? Of course, it's to checkmate opponent's king. But it's that simple only if machine is playing against machine. Humans like a good show, and a good player will do stylish actions like teasing opponent or making honourable concessions to make a good show. Even if he gets checkmated, spectators could consider him as winner, if he'll lose stylishly.

But what if stylish actions would be necessary formal conditions of winning?..

Rules

Game is played as regular chess, but checkmating is not main object of it. The winner is the player, who will get more points for various achievements, even if he is checkmated. I recommend to play several games, summing points, to make it more interesting, but one game is already enough to make it different from standard chess.

Checkmates

Though checkmating is unnecessary, it's still the most valuable achievement.

• Checkmating with queen, adjacent to hostile king - 100 points.
• Checkmating with non-adjacent rook - 110 points.
• Checkmating with non-adjacent queen's orthogonal move - 120 points.
• Checkmating with knight or non-adjacent bishop - 130 points.
• Checkmating with non-adjacent queen's diagonal move - 140 points.
• Checkmating with rook or bishop, adjacent to hostile king - 150 points.
• Checkmating with pawn (non-promoting) - 200 points.
• Checkmating while castling - 500 points.

Note that in the list above "checkmating" pieces are the ones attacking the hostile king themselves, even they did not move. But if another piece were moved, unblocking it's path, it gives bonus points (it's more stylish!).

• If knight were moved, it gives 20 bonus points.
• If bishop or rook were moved, it gives 30 bonus points.
• If king were moved, it gives 40 bonus points.
• If pawn were moved (with or without promotion), it gives 50 bonus points.

If the moved piece reveals check and also now attacks squares adjacent to opponent's king, that were safe before this move, it gives even more bonus.

• Rook - 10.
• Bishop or knight - 20.
• King - 30.
• Non-promoted pawn - 50.
• Pawn, promoted to queen, if both diagonal an orthogonal moves has attacked safe squares - 55.
• Pawn, promoted to rook - 60.
• Pawn, promoted to queen, if only its orthogonal moves are used - 65.
• Pawn, promoted to bishop or knight - 70.
• Pawn, promoted to queen, of only its diagonal moves are used - 75.

Double check

In case of double check during checkmate, player gets checkmating points from checking pieces that gives less checkmating points. However, player still gets bonus points of unblocked attack, even if the piece that moved is the one that gave checkmating points.

Other achievements

Capturing bonus

Promotion

In overwhelming majority of cases, pawn is promoted to queen in normal game. Yeah, it's reasonable to promote to stronger pieces.. But more stylish is to tease opponent and promote to weaker piece!

NOTA BENE: promotion bonus should NOT be added if promotion move is checkmating move: think that promotion points are included in bonus of checkmating by promotion.

• Promotion to queen - 7 points (well, the fact of promotion is achievement itself, and it should be encouraged in any case).
• Promotion to rook - 10 points.
• Promotion to bishop or knight - 20 points.

Draws

Often, if player is seeing that he will lose, he'll try to lead game to draw. But this is done only to "not lose". Well, let's encourage this at least in this game.

In any draw outcome, except for two bare kings or only two kings and one bishop/knight, points are given to the player who has less total value of non-royal pieces (pawn costs 1 point, bishop or knight - 3, rook - 5, queen - 9). Player gets sum of difference of his and opponent's forces and difference of his force and maximal possible force (39). E.g., if one player has one knight, and his opponent has one knight and one pawn, difference between their forces is (3+1)-3=1, and the lack of weaker player is 39-3=36, therefore the weaker player gets 36+1=37 points. In case of two bare kings or two kings and one knight/bishop, the player who made last capture gets 50 points.

Resigning should finish the series of games with summation of points, and resigned player loses regardless of number of points.
