Some more ideas

[Lyudmil Tsvetkov]

This is a very major term for the mg.

Sf, for example, completely does not understand it.
As a result, both its attacking potential, and its king safety suffer.

I know that apart from the usual bonus points for rooks on open and semiopen files, both very major terms too, many people also give bonus when the rook is on the file where the enemy king is or the 2 adjacent files.
Very reasonable bonus, and I am curious how this is tuned and performs in different engines; please post feedback, if available.

I am curious, as this would interfere with existing bonus for rooks on open and semiopen files, so giving an ad-hoc bonus should not be very easy to tune.

My specific suggestion to avoid random tuning is the following: give the bonus in terms of whether the files where the rook is is closed, semiopen or open. This might help distinguish the importance of different rook locations that could later be finetuned as specific subterms.

Again, finetuning is important here, as this is a very major term, related to king safety and, as you know, king safety matters a lot.

I would give the following bonus points:

- 10cps for a rook on a closed file if the enemy king is placed on the same file
- 7cps for a rook on a closed file (one own and one enemy pawn, or just one own pawn) adjacent to where the enemy king is placed
- 15cps for a rook on a semiopen file against the enemy king (the file where the enemy king is and the 2 adjacent files)
- 25cps for a rook on an open file against the enemy king (obviously, the 2 adjacent files)

Those would be overbonuses over the already existing bonus points for open and semiopen files.

[d]1k4k1/1p4p1/p1p5/2P5/P1R3P1/RP6/6R1/1K4K1 w - - 0 1

above, 10cps for Rg2, 7cps each for Ra3 and Rc4

[d]1k4k1/1p4p1/p1p5/8/2R3PR/R7/1R3R2/1K4K1 w - - 0 1
15cps for Ra3,Rb2 and Rc4; 25cps for Rf2 and Rh4

Again, it does not matter that in many cases such rooks on open and semiopen files will also directly attack the shelter; quite frequently, they would not, as there would be other own or enemy pieces in front of them, so the bonus would be very appropriate, if you would not like to rely entirely on the search, which might not be the perfect idea, as king safety is very deep and often branches out significantly.

So you really need this additional bonus, finetuned to specific situations.

At least what I see with SF, which is supposed to be a tremendous attacking engine, is that it misses such subtle rook moves extremely frequently, whenever the lines are deep; of course, with shallow lines, it sees everything.

Any feedback on how you implement that term and what elo benefit have you derived from it?

[Lyudmil Tsvetkov]

I forgot to mention, that a small, but a very efficient trick is to score higher, maybe even with double values, rook against the enemy king on an open edge h or a file.

The reason is simple: attacking along those edge files is much more forceful, as it is very difficult to organise the defence here, as there are no defenders on the other side of the board/across the board.

Engines in general do not understand that rule.
It is as easy to mate SF along the h open file, adjacent to the enemy king, as it is to mate Skipper.

I see Joerg has pushed a similar patch on fishtest.

I wonder if Jerg could consider trying a version with bonus only for an edge h or a open file, and only for the mg. Of course, giving a bonus also for the eg for that term makes absolutely no sense.

I think for SF some 30cps bonus only for the mg for a rook on an open h or a file adjacent to the enemy king could be about optimal.

Joerg, after all we must do something, must not we?

[d]4r3/3nrpk1/1p1qb1pp/p1ppN3/3P1PPP/P1P1R3/1P1Q2B1/4R1K1 b - - 0 30

SF has just played f3-f4, staying completely without a pawn shelter on its 2nd and 3rd ranks. This might already be the losing move.

[d]3qr3/2r2pk1/1p2b1p1/p1ppP1Pp/3P3P/P1P3R1/1P1Q2B1/4R1K1 w - - 0 34

both SF and Houdini show 0.0 here, but white is already lost. The white king simply does not have where to hide, and this is still well into the middlegame.

It might take some time until white gets mated, but that will happen sooner or later.
It takes black another 25 moves/50 plies to prove it is winning, so that search will not always or even very rarely help in such positions, as the win is usually deep or very deep. You should simply have such an eval term.

[d]1r6/2r1qpk1/4b1p1/1p1pP1Pp/p2P3P/P7/1P1Q1R2/3B1RK1 w - - 6 42

both engines see here only 50cps black advantage, but soon this gets to 5 full pawns. White is completely lost, the white king simply does not have where to hide, and the king as a rule needs at least a single pawn on its 2nd and 3rd ranks to be fine with king safety. Having just a single pawn on the 2nd and 3rd ranks of the shelter is just fine, but lacking this last one already is extremely dangerous. Therefore the penalty is fully reasonable in the mg.

Of course, the king could do just fine without any pawns in the shelter on the 2nd and 3rd ranks, but the player should have in this case sufficiently weighty other advantages to compensate. In this game, SF does not have such.

Again, as you see, no pawn shelter is one thing closely related to king safety, 3 blocked storming pawns is another thing; king safety has a wide range of specific features, if you know how to implement them and are lucky enough. Especially the second one.

Now, SF badly needs such a term, but the chances for a reasonable patch to pass on fishtest are maybe 1 or 2%.
I wonder, if SF does not see the loss at very LTC, how is it going to see how to adequately proceed at 15 sec. for the entire game?

[Lyudmil Tsvetkov]

I bet that additional bonus for rook on adjacent open file to the enemy king, if file is edge a or h file, is a very good term in respect of chess knowledge. Very good, very symmetrical and very necessary.

SF loses heaps of games because it lacks such knowledge. Couple with a deeper search of course.

But on fishtest this simply does not work. I can not explain to myself why.
Well, if SF does not see how to proceed even with 5 minutes or more per move when king safety and a/h open files are involved, how is it going to see that at 15 sec. for the entire game?

One way or another, I stick to my claim that rook against the enemy king - all terms related to rook on open/semiclosed/closed files against the enemy king - are very major and necessary eval specifications.

As they are closely related to king safety, maybe trying with longer TC might be more accurate in assessing virtues of the idea.

[d]r4rk1/pp2q2p/2nNpppP/2P1nb2/5RP1/2P1B3/P2QB3/5RK1 b - g3 0 23

Critter has just played g4 with white, staying without pawn shelter on its 2nd and 3rd ranks.
The penalty for no pawn shelter is of course due, but here Critter has sufficient other advantages: advanced h6 storming pawn, when this is the only blocked storming pawn, advanced knight outpost on d6, pair of bishops, etc. So, basically, you can afford staying with no pawn shelter, but only under specific conditions. So it will be a matter of tuning what the precise penalty for no pawn shelter should be.

Once I thought tuning has no significance at all in computer chess, but now it seems computer chess is all about tuning...

[d]r4rk1/pp2q2p/2n2pnP/2P2Rp1/3B2P1/2P5/P2QB3/5RK1 b - - 2 26

2 of the white storming pawns are blocked - h6 and g4 - but not the 3rd one, so white still has the semiopen f file at its disposal for attacking purposes.
