So far, I have these enlisted, and some work in progress: I hope I don't run outta ideas.
  • Pawn structure:
    This is the work in progress. Attacking the opponents pawn to make it isolated, trading pieces to make it doubled. etc

    Queens and rooks to the 7th
    Placing the queen and Rook on the 7th or the 2nd rank to pressurize the opposing side.

    Massing near the king for the attack
    Arranging useful pieces that are necessary for king side attack launch.

    Pawn storms
    Or pawn chains, pawns wedge, pawn nail.

    Destroying the castled king’s defenses
    Like creating weak squares in opponents king side pawn cover.

    Limiting the mobility of pieces.
    Fixing up pawns to limit the mobility of pieces.

    Recapturing
    Which pieces to use to recapture. cxd5 or exd5 or Nxd5 etc etc

    Avoiding En-passant/ doing en-passant.
    Do enpassant only if you can weaken opponent's pawn structure, else not.

    Blockading:
    Bloackade the passer pawns with one of your pieces.

    Overprotection/Overworked Pieces:
    protect the certain pieces further, especially the ones that control important squares/centre.

    Sacrificing a pawn for better activity
    This happens in Benko gambit, but hafta find them in middle games.

    Square Vacancy:
    Occupying the vacant squares on enemies camp in order to create more pressure in surrounding areas (What's shortest term for it? pressurizing perhaps?)

    Tempos:
    Giving tempos either with a pawn or with pieces.

    Simplification:
    Simplification simply means to simplify the position by exchanging pieces when you're materially superior or positionally superior. Engines could find simplification easily, but I'd want to look for difficult simplification puzzles.
Any more ideas are welcome! Along with diagram, showcasing engine's analysis as an example. etc :)
- Queens exchange decision: positions that makes a decision of queens exchanging or avoiding it

- Rook choice: there are certain positions where you must centralize a rook. For example, you can move two rooks to d1: one from a1 and the other from h1; one of those moves is often wrong.

- Prophylaxis white: h3 - black: h6: positions where it is wrong and positions where it is required.

2 More Ideas...

* "Principle of 2 weaknesses" -- Important strategic concept.

* Transfer of pieces from queen side to the center/kingside and vice versa. (changes focus)

Hi Fermin,

Why should there be test with moves that are illegal? I think all stable engines make legal moves.

Good idea. I hope the engine wouldn't make a move on reflex due to the opening book, when solving the position.

I did not refer to legal move rules, but to typical evaluation rules like place always knight in the center, castle soon, bishop pair is always good, ... and so on.... There are always exception where typical rules of thumb are not always adecuate.....

* When to castle and when NOT to castle

Many engines rely on their book to castle at the right time, once out of book before castling they tend to castle at all costs

of course engine should not use their books during test.


here is my test position number 1.:

1.e4 c5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bb5 e5 5.Bxc6 dxc6 6.Nxe5

6. ...Nxe4 the only right move.

have some other positions. plus for the right moves, minus for bad moves -points scaling.
