A treatise on RJTC.

Well, what to do when goaded by such a post? Your friendly chelonian RM-Sanctus here to expound on this variant of Chinese Chess.

So, allow me to demarcate the borders of this discussion. Firstly, the variant is the no-capture, bing-swap as in the previous post. In the second, invulnerability traps will apply at any instant (in the astronomically unlikely event a ma jumps into a wall of friendly pieces blocking the last check your opponent has and removing your last checking piece, it is a draw.)

Well. The value of pieces, I gather, is a subjective notion that cruxes on one's playstyle. For the most part, I agree with ph42's assessment of the values. However, let's dive a level deeper into this weighing.

When captures are out of the question, the concept of piece valuation takes on a different meaning. No longer is it a judgement of material on the board, or the likelihood of an endgame. Instead, it is a dynamic evaluation of the relative strengths of available pieces. Some pieces are inherently better at defending (xiang, shi, to some extent pao) while others are good at attacking (ju, very very much ma). Considering in light of this the units available:

Side bing: generally slows down your own attack, and does little for defence. Tempi can be traded by pushing one and forcing your opponent to mirror that to blockade. In stuck positions, can be the source of a slow flank attack. Not a great piece.

3rd/7th file bing: Closer to the king, the sides of the central river stalemates, and very dangerous if allowed to cross the river. Typically both sides push theirs in a race to the kings, or blockades with xiangs for a slower game.

Gokigen central bing: A default. Surprisingly fast if pushed crazily forward, yet easily stonewalled by standard defences (usually castles around the palace.)

GHB (Across river bing): Very scary. Harder to stop than before, and once it gets near a king, blood will follow soon. They can kick the general around with impunity, and are very likely to squash the king against his own pieces. Great Holy Bing.

Shi: The backbone of defence. Occasionally the appendices, performing little function but to throttle the general as he is contact checked to death. Still, these are essential in guarding 2 of 3 directions the king can be attacked from.

Xiang: Best used to stop 3rd/7th file bings, or to block irritating bottom-line attacks. They may only have 7 possible locations, but 5 are pretty important locations.

Ma: Main source of headaches. These things are horrible to move, making enforcement of the invulnerability rule brain-sapping to test for. The main bane of "invulnerable" fortresses, and a brilliant piece to probe for weaknesses with. If trapped on the wrong side of a barricade, though, they're quite useless (in defence particularly.)

Pao: A bing would sometimes be better. They move like jus, start in aggressive locations, and don't actually get to do much of the killing. Generally, they should stick to what they're good at: Posturing, locking up the opponent's flanks, the river, the palace, [everywhere], abusing their fast movement. Some pins, too.

Ju: The slow-to-develop, main killing piece. They speed through open lanes past blockades, but zigzag highways are their bane. Good for threateningly holding up river positions and half-open lanes.

Jiang/Shuai: ...
Do you seriously expect fei jiang (flying general) to be of ANY use here?



So those are the pieces. A typical game would flow something like this.

Opening phase: Key strategies are decided. Block the 3rd/7th bings? Try to stuff a pao into your opponent's palace fast? Swap pieces across the river or set up a nigh-impermeable roadblock? Important to consider are speed of bings, the open lanes that should be controlled by paos and jus a.s.a.p., and the opportunity to lock up pieces before they move, trapping them in a corner and thus creating a "material imbalance" of numbers.

Middlegame: If it's still pretty even after the opening, there are 2 possibilities. Firstly, both sides have pieces across the river, or perhaps 1 or 2 bing pairs have been swapped. A blitzing game ensues, where both sides race to deliver fatal charges and counterattacks faster than the other. Or, it's a delicate situation with the river choked with not a delta but a mess, in which case a slower game of attrition, temporary "shifting" blockades and side bing attacks follows.

Endgame: If one side has distinct material advantage near the opponent's palace, capitulation soon follows.

Positional evaluation is easy, but can be more subtle. The main rule of thumb is: the closer the centre of gravity of the board is to your king, the worse off you are.

I wonder who wants a game of this, on playOK or something?

Boring holidays...

The holidays are officially making me feel bored, and as such I shall talk about stuff today. Ever since Tux has started posting despicable vocabulary to instill sheer terror into the hearts of all those not protected by a lexicon, ethereal or corporeal, I have thought that this blog was getting diluted. And hence I guess... RJT Chess!

Yes, it's that no capture chess again.

Today I shall be talking about RJT chess in general, as nobody (really) has bothered to play this modern variant of chess, where no blood is spilled (apart from splitting headaches).

So firstly, the value of pieces.

Bah! Zerothly, I shall be talking about the variant where pawn swaps are allowed (Carnage of the bings!) and as far as I can remember, no other weird new rules.

Back to firstly. I must roughly give an idea of what the value of pieces could possibly mean in a chess that has totally nothing to do with trading pieces and praying that somehow it was a good trade for you. Also, the value of pieces does not accurately reflect how likely they are to wreck havoc in your opponent's base and win you the game. For such a turtlish (check RM-Sanctus' dictionary and possibly mind for details) variant of chess, if you want to win, you must get many many pieces, or actually, all your pieces as close to your opponent's king as possible. And he can still block... But with enough luck and perseverance, you will eventually force the game to an end (in somebody's favour, and after an innocent couple hundred moves).

I know this sounds like an essay written by a stressed student trying to write a story but failing to think of ideas, giving rise to lengthy preambles, but hey, the context is suspiciously similar.

Fret not! I have content *hurries to make up nonsense on the spot*.

So what do I exactly mean by value? Value is the amount of headache a piece can cause your opponent.

Yet again, I deviate to put across a more complete picture.

...
... ...
... ... ...

Imagine.

Imagine...

You are playing RJT Chess with your friend, and it is in the middle of the afternoon, and you are sitting on a stuffy table without a fan. Or air-conditioning.

You take out a flimsy chessboard, and start playing.

Time seeps by, and flies like an arrow, at the rate of 0.0167 minutes/s.

Without your knowledge, it is already dinnertime. And the match still isn't over.



Moral of story? RJT Chess is really a game of attrition at high levels, and whoever gets a migraine first loses.

As a result, here's a rank of the value of pieces, from the pieces that stone and rot in a corner of the board for the entire game, to the ones that jump around and cause chaos.

1) Advisor (shi) -- Pretty useless, doesn't even block the king probably most of the time.

2) Elephant/Minister (xiang) -- Can block 2 bings from crossing the river. And will probably rot there until the end of time as well.

3) Cannon (pao) -- These insanely tricky things in the actual Chinese Chess tend to fester quickly in RJT Chess, as violence is no longer permitted.

4) Chariot (ju/che) -- These things are rather easily blocked, and hardly cause a headache.

5) Bing (!!) -- Once these creatures get near, the game draws to a conclusion. The king cannot run too much, or risk invulnerability (and hence breaking a rule), yet once checked by a bing, the game is almost over.

6) Horse (ma) -- Always the source of checks, on average 14.159 moves checks to be exact. These things are your Lodanap.

7) King (jiang) -- need I say more?
