  • Playing Against an Outpost

    Playing Against an Outpost

     

    In the diagram White has an outpost on e5, but Ne5 can always be met by …Nxe5 and after recapturing with the pawn, White’s outpost is gone. White needs to bring another piece to bear on e5, so White to move would play 1.Bg5 and follow it up with Bh4 and Bg3. If on the other hand Black is on the move, he would seek to prevent this with 1…h6, or a more active solution 2…Qe8( so as to meet Bg5 with 2…Qh5! threatening Rxf3) or 1…Qb6. Either move gives Black a fine position.

     

    If you are unable to cover your opponent’s outpost, then extremely active harassing tactics are needed.

     

    The diagram is from Unzicker – Fischer, Varna 1962.  If you are unable to cover your opponent’s outpost, then extremely active harassing tactics are needed. In this position the White knight is at least four moves away from reaching d5, this gives Black some breathing room to prevent it, since after the White knight reaches d5 White is lost.

    1… Ra4 Immobilizing the knight. 2. c3 Qa6 3. h3?  Rc8 4. Rfe1 h6 5. Kh2 Bg5 6. g3 Qa7 7. Kg2 Ra2 8. Kf1 Rxc3! White resigns, as after 9.Rxa2 (9.bxc3 Qf2#) Rf3+ 10.Ke2 Rf2+ 11.Kd1 Qxa2 his position is wrecked.

    The lessons to be learned here is that structure alone is not quite everything. The pieces must be able to coordinate with the pawn structure.

  • Calculating your Chess Rating and Knowledge

    Here’s a fun exercise to determine your estimated chess rating taking into account your existing chess skill and knowledge. While this is just for fun, it can prove helpful in determining how you should focus your chess training. If your knowledge rating is much higher than your skills rating, then you you need to focus your training towards skill building where if your skill rating is much higher than your knowledge rating, then you need to focus more on book learning. You should strive to have your knowledge and skill ratings at no more than 100 points apart.

    Here’s how this works.

    Formula: (Skill + Knowledge) / 2 = ELO

    You need to plug in two of the numbers, and the two best to plug in are ELO and Skill. Ideally, you would use your USCF rating, but if you don’t have one, you can use your ICC of FICS rating, just remember to subtract 150 from your ICC or FICS rating so that it approximates an official USCF rating.

    For your skills rating, I would use Igor Khmelnitsky’s Chess Exam and Training Guide to test your skills and get a rating approximation.

    Example:

    Skill rating: 1138 (based on Khelmenitsky’s book)
    USCF ELO: 1340
    Knowledge rating = K

    (S+K) / 2 = ELO

    (1138 + K) / 2 = 1340

    1138 / 2 + k/2 – 1340 = 0

    569 + K/2 – 1340 = 0

    k/2-781 = 0

    K=781 * 2

    K= 1562

    So my chess knowledge rating equals 1562, while my chess skill rating is approximately 1138 giving me an ELO of 1340. This means I have to focus on getting my skill rating to par with my knowledge rating in order to play at an estimated 1562 ELO rating.

    The goal should be get my skill rating within the same ballpark as my knowledge rating (+/- 100 elo points) before focusing on adding more chess knowledge.

    You should repeat this process every three months, but you will need to take the skill’s test again as well as play in a tournament in order to update your USCF rating and get an accurate reading.

    I would love to hear feedback on this, especially if you actually try it out.
