 By Charles  Daniel. Venomous. New system of chess on 10x10 board with new pieces: the Sorcerer Snake and the even more venomous Sissa. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]

This looks pretty good, but I do not like Ninja Pawns, unlikely ever to have wide appreciation. Interestingly they gain strength in boards' upper half. Sissa goes well with (N+Zebra)-hybrid. Upwards of fifteen CVs in Pritchard's 'ECV' use (N+Z) going back 100 years. They are mostly leapers exclusively. Differently, a couple of them require Knight-space clear, to either stop there or optionally slide one more to Zebra(2,3). These mostly have accompanying (N+Camel) separate piece. So straight two-path  is unique and creditable. This Snake(N2,Z2) amounts to Moo (1960s) plus two pathways of Falcon's (1992) six in legitimate tinkering. The companion piece-type Moo + two-path Camel is obvious follow-up, and expect to see it in the spirit of proliferation. In 'ECV' (N+Z) is not the commonest compound, which would be among RN, BN, and RB, but (N+Z) is in the top 50 for frequency; others like K+N,AD,AND,WAD would be a lot higher. Truelove's can validate accuracy of the last sentence. Both (Moo+Zebra) and (Moo+Camel) are logical complements themselves to further Sissa for 10x10 Track II material. Remember Track I and Track II are not value judgments, but I OrthoChess replacements-to-be and II CV art per se. I think this Venomous could be as good as Centennial and number of other 10x10s. If we were ever rating precisely, we  need scale 1 to 1000. Then if we get 'goods' as the highest '10x10s' so far, they would cluster like 650, 645, 639, 637, many really close together. I do not think '10x10' is yet ''solved,'' as '8x10' is already solved, until there are one or two that get 900 out of the 1000. As Hutnik says, 2c=2c=2c; or does it really?

Good to see the Sissa in action again! Love the new symbol for the Sissa!

Very interesting new piece the Sorcerer Snake... It feels like a longer range Knight, yet it's not a leaper, and is a cousin of the Sissa, as the path to it's destination square must be unobstructed.

The Sorcerer Snake's movement is actually easy to learn, and understanding it can make it easier for beginers to learn the more complex movement of the powerful Sissa.

Well done Charles!

PD. Just curious why didn't you also improved the Bishops and made them Wazir-Bishops (since you improved the Knights)?

I cannot less than celebrate, Charles, your choice of including the sissa in one of your game designs. Excellent!

Certainly, this piece has not been adequately explored in other chess systems. I have had the oportunity of seeing some of its peculiarities on an 8x8 board starting from the randomly positions of my Cetina Random Chess and Cetran Chess 2 proposals.

'Instead of boring the player with arcane references to complex, convoluted, and contrived theoretical jargon,...', as you just say, I would like to show here some samples of THE SISSA IN ACTION!

At the following position White to move:

White moves Sc1+ [moving path: d1-c2-c1 or d1-d2-c1 / checking path: c1-h1-c6]:

At the same time the sissa is menacing the rook by c1-c2-b3 or c1-b2-b3. Obviously if Blue moves his king, would lose his rook. Fortunately Blue has salvation by moving Rf3 that obstructs the h1-c6 diagonal, interrupting, cutting the check:

At the following position Blue to move:

In the real game Blue moved Kd5, but what would happen if he moves c4?...

... White would make Sa5+...

... moving path: b3-a4-a5 / checking path: a5-b5-c6. Notice that the sissa covers both b5 (a5-a6-b5 or a5-a4-b5) and d5 (a5-a8-d5). Blue is losing his pawn on c4, so Kc5 is unique...

But now White makes the surprising and spectacular movement Se5+!

Moving path: a5-a1-e5 / Checking path: e5-c7-c5 or e5-e7-c5 or e5-e3-c5.

The sissa covers
b5 by e5-e8-b5;
c6 by e5-d5-c6 or e5-d6-c6 and
d5 by e5-d6-d5 or e5-d4-d5 or e5-e6-d5 or e5-e4-d5.

Blue has two options: Kd6 and Kd4. If makes Kd6, obviously would lose his pawn on c4. And if he makes Kd4? Let's see it:

Then White wins the rook by moving Sd7+...

...moving path: e5-e6-d7 or e5-d6-d7 / checking path: d7-g7-d4 or d7-g4-d4. The rook is captured by d7-c7-b6 or d7-c6-b6.

Viewing these examples of what the sissa can do on an 8x8 board, we can hope reasonably that on a 10x10 its powerful will be increased greatly, overall by acting in combination with the remain venomous pieces.
