I've been meaning to create a new thread where we can post interesting and well-played engine games, preferably annotated (by humans), so the readers can both enjoy and be edified and stimulated by what's presented to them.
To get the board (uh, I mean ball ) rolling, I'm posting a diagram from a very recent game. Please try to come up with a good move for Black on your own.

Not sure fen diagrams can be posted here so I'll try to post a board capture image.
I will post the full game just a little later.

The position comes a very recent game between Thinker, a strong and aggressive player in its own right, and the private strategic engine SultanKhan 2.0, inspired by and modeled after the very talented Indian player from the 1930s. I wanted to show how a smart engine can play the Benoni very enterprisingly and successfully, which is a very rare sight in computer chess.

[*what's interesting is that further analysis suggests that 21.. .h6!!, a move earlier, was perhaps even stronger (hah!)]} 0-1 [/pgn]

I discovered that the pgn4web display was only buggy because of some extra characters in the pgn, which I then deleted.
