IECC THEMATIC CHALLENGES:

last update: November 09, 2019

* Name of Thematic (see list below)

WE WILL ATTEMPT TO ASSIGN OPPONENTS WITHIN A 400 POINT RATING DIFFERENTIAL. THE TD MAY USE HIS DISCRETION AND ASSIGN OPPONENTS WHOSE RATING DIFERENTIAL IS BETWEEN 400 AND 500 POINTS. HOWEVER, IF THE OPPONENTS AGREE, THE TD WILL ASSIGN OPPONENTS WITH A LARGER RATING DIFFERENTIAL (ABOVE 500 POINTS).

This is a great way to explore specific openings. You play either a two-game match, both as black and white, or a one-game match where you decide the color you would like to play. A list of players waiting for opponents appears below, along with popular variations with no players.

You can also specify a variation that does not appear on the list . You may specify a minimum or maximum rating for your opponent. Otherwise, we'll assign an opponent within 400 points of your rating at the time That the match is set up.

How to Request a Thematics Match

Complete and submit the game request form on the Thematics Event Web Page, making sure to include all the required fields, marked *. If one-game, let us know the color you'd like to play.

Special notice

In order to leave room on our waiting list for new variations and to limit the accumulation of very specialized requests, we are having to establish limits.

(a) Requests older than a year will be deleted. You can get your name back on the list by making another request.

(b) Unusual variations will be deleted after three months at the discretion of the Tournament Directors. We will strive to retain variations that might be of general interest.

(c) New variations will ONLY be accepted if the requester will play a two-game match with no special rating request.

(d) New variations will be limited to 7 move pairs.

We appreciate your understanding.
