Zappa played 27. .. Ke7, which looks funny, but is not bad. In fact, against
Deep Sjeng (and countless other programs) it is the winning move. Like a red lap
against a bull, Deep Sjeng replied with b4?? which is losing. Black's king looks
exposed in the center but is in reality unassainable, instead *white* must be
careful. Zappa must have seen it because the score went up immediately after b4.

White can at least draw with 28. a4.

Your mission is: avoid 28. b4

49. Rb1 loses instantly because after Rc3, white is in zugzwang! Deep Sjeng
could not avoid it because of that. Can your program (and does it understand
what is happening)?
