How about you tell us?

Or rather, why should we care?

Or rather, why are your questions other people's responsibility?

The problem with "ignore user" in here is terrible.
In many forums, if you ignore the user, you dont see that user's posts anymore.

In here, look at this.

I still see the " Title of such useless posts " everyday in msin menu.



Only under the title, it just ignores the user post.




This discourage me visiting to this forum lately.

Indeed Joe, it is the very defintion of one who is parasitic, one who exploits the hospitality of others without returning anything of value...

Indeed, the ignore button should make posts not even visible to those who we have chose to ignore...

What's going on here? I never seen someone post a position and people being snippy about it. Someone usually post engine analysis on it.

As best I can tell, some people find Chessqueen's posting style to be too intrusive. Odd to attack him when he's posted a puzzle though.

Regarding the puzzle, I haven't done any engine analysis, but at a glance, it looks as though white is going to have to give lots of checks on the way to the solution, to prevent black's knight and queen from becoming active.

After some Forward- Backward of lines to exchange of Knights, wich are drawn 6men like e.g. this one:

[d]8/8/1B6/1B2q3/8/1R6/6k1/2K5 w - - 0 17

Output with full hash from Backward of such lines:

[d]1q2B3/N7/8/8/8/3k4/5R2/2K1B2n w - - 0 1

Funny, but yjadeg (yet just a drawn endgame) according to 50 moves rule.
Of course, we could call it a study and thus set this one drawing- rule out of order, but I don't like to do so
