But it may be convincing in eliminating an 1. ... hxg5 response from black. >Black has many alternatives. It is just a start as stated and not meant to be a complete analysis. Given the complexity of the position, it is important to eliminate moves in black's defense.

What are Fritz's lines for these other choices? What was Fritz's evaluation of hxg5? >There are also a lot of alternatives in later moves. > >White has to demonbsttrate a win against all these options in order to convince >me that Ng5 is winning.
