Just another one of my novelties being tested on Crafty.

Looking at your rating and annotations i think its basically an invitation to get checked for using a program is your games.

This actually transposes into a rarely played line in the Catalan.  Usually the White queen lands on c2 and the black rook goes to c8.

Why doesnt white just do 47 Qe8# anyway?

Black didn't "force" a trade at all, he "offered" one.

kdelaney -- I try to post something that I find interesting, saying what I find to be an appropriate explanation of ideas without having too many complicated side-lines, and I receive a response about being checked for cheating?

KillaBeez -- You are correct, sir. I believe it gets the label of "English Opening: Agincourt Defense, Neo-Catalan Declined"

4m4z1ng -- Black is giving check on move 46, forking white's king and bishop. White is the one who is forcing the trade, so as to simplify to a win.

Manic Dragon --

Oh right. This is embarrassing.

He traded his queen for your bishop around move 24, what was that about?

Black doesn't really have too much of a choice, as there aren't so many squares (only 2, actually) available for the queen -- a5 and b5. If the queen retreats, then white still has the knight fork on d6, not to mention that the black queen has already moved too many times. For example:

24. ... Qa5; 25. Nd6 Bxb2; 26. Rxb2 Qxe1+; 27. Rxe1 Rb8; 28. Nxe8

24. ... Qb5; 25. Nd6 Bxb2; 26. Rxb2 Nxc8; 27. Rd2 Qe8; 28. Qd1

It's the typical (and oft-times flawed) computer logic of cutting losses or damage control -- go down as little material as possible and try to salvage the position. The human reaction, of course, is to try to avoid simplification in the hopes of getting an attack going with whatever material is remaining.
