First of all the line you give as "forced" is not forced. I guess it was provided by the "experts" who said it was a great sac. I doubt that computers can prove that Bxf5 is either good or bad at this time. There is still a lot of chess to be played after gxf5. Even gxf5 may not be the best response. Jim
