Odin's Rune Chess. A game inspired by Carl Jung's concept of synchronicity, runes, and Nordic Mythology. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]

In either case, since a stalemate draw cannot occur, the obvious conclusion, whether or not a king can pass, is that the side with a lone king (or 2 lone kings) loses, either by it/them being taken, or being unable to move.

Just to make perfectly clear: any piece may capture a Lion, that has captured a Lion on the previous turn. Restrictions ONLY apply after a non-Lion captures a lion. This rule has been incorrectly written in some parts of this site, which I have complained about before. And thanks for working on a new preset, Adam ^^

I will test to make sure everything else is in order

Would you share the link to your newest preset, Adam?

Excellent, passed all my tests. Thanks again! I will be using this preset from now on.

So, I switched to Firefox. It appears to be working better now. Still very weak AI

It takes many tempi to attempt to promote a Lance. Edge attacks have never been my favorite, so I haven't had much experience in playing for such promotions, until very late in games. However, based off opponents who have tried to move along the edge files, and my defense against such attacks, I have concluded that early edge pushes require at least 20 tempi of preparation to be mildly successsful, against someone who is not exactly interested in the same. A player can comfortably defend, at least for a while, but the edge file attacker can get through at least one promotion exchange if they put enough in it, this usually being some exchange like Dragon-promoting for Rook. A player must be particularly careless to allow a Lance to promote safely and flee.

Overall, I don't rate Lances that highly, perhaps around the same as a Kirin.

Using my (pre-adjustment) piece value table, under early middlegame, the value ranges given are as follows:

  • Pawn -2.5/4/6 (Tokin 9/9.5/10)
  • Go-between 8/8.5/10
  • Bronze 6/8/9
  • Silver 8.5/10.5/11
  • Leopard 9.5/10.5/11
  • Lance 14.5/16 (White Horse 25/26/27)
  • Kirin 18/19/20
  • Bishop 24/26/29

Then I adjust the values using things I know about the position, which can easily swing them a further 20% for ranged pieces, 40% for small pieces, and 200% for individual pawns.

I wrote the table to suit my personal style, at the behest of one Andrej Trauner, so it may not be applicable to others. I believe it a safe assumption that my table is the most thorough estimate of chu shogi piece values in existence, especially when combined with the list of adjustments, which only exists in my head.

I don't put too much weight on material advantage when playing. It only accounts for roughly 35% of my evaluation, compared to about 60% for purely positional considerations.

 


Shogi. The Japanese form of Chess, in which players get to keep and replay captured pieces. (9x9, Cells: 81) (Recognized!)[All Comments] [Add Comment or Rating]

Indeed, there is a rule against perpetual checking, as an extension of the repetition rule. The repetition rule states that if a position is reached for a 4th time, with same pieces in hand and same player to move, the game is no contest, whereafter colors are reversed and a new game is started. Players get to keep whatever remaining time they had, with a minimum time normally granted.

However, if such 4-fold repetition is a result of consecutive checks, with no single non-checking move, then that attacking player is at fault and loses. A player could potentially give dozens of consecutive checks, before the repetition becomes illegal.

Repetition is already rare enough, especially at the amateur level. Very few instances of perpetual check repetition occur. Most people who see it as a possibility deviate the 2nd or 3rd time around, or avoid it altogether. I found only a couple actually pertinent videos on Youtube under the search 連続王手の千日手

You left out a "d" in the last "sandbox". It works fine.

Canadian "team" - singular. And by a loose definition of "compete", since the Toronto Blue Jays aren't particularly good, haven't won the World Series since 1993, and have only made the playoffs twice since then.

Yeah, I liked how it was before better. The dropdown menu of legal moves is a good addition, so long as it doesn't interfere with a player's ability to click and move as one would normally do. I could see myself using the dropdown menu to enter lion moves (chu shogi) in the future, even considering the time it would take to scroll through 100+ legal moves.

That is an improvement. I like how it assumes the move is complete after a non-capturing first step. I also like the "pass" button. Yes, a pre-selected lion would be an improvement.

The preset has recently been changed in a way that makes it worse than it was before. Now, simply typing "pass" for the second leg of a move does not append to the first leg, nor does the newly added "pass" button work as it should. I liked how HGM handled it in his Mighty Lion Chess preset.


dax00 wrote on Thu, Aug 13, 2020 08:47 PM UTC:

It still says "You may not move more than one piece per turn" when trying to pass the second step of a lion move.


dax00 wrote on Tue, Aug 18, 2020 12:59 AM UTC:

Until Adam's preset is fixed, I don't see much of a choice but to use the non-enforcing preset. Puzzles me why an update would just make things worse.

It doesn't make any sense to use a piece whose movement is widely known to be that of the cannon (from xiangqi) and call it something else, while calling another piece a cannon. The solution is simple: switch the names to follow convention. Van to cannon, cannon to van.

Just a note about probabilities. There's actually an 11/36 (30.6%) chance of rolling a specific number, and the chance of a double is 1/6. So the probability of activating the rolled-double ability is 11/216 (5.1%). Even then, it's far from guaranteed that the piece type chosen by that double is able to capture a piece, or that such capture is desirable.

I can't access my game that was interrupted. I hope that timed-out games (due to the site being down) will be playable soon.
