This is from an a analysis line of Ljubojevic-Andersson 1976, one of the most
exciting games of all time. Black just played Ne8xBc7 (in the game it Bb5? was
played) and now the best for white is Bxh7+ Kxh7/ Qxg7+ Kxg7/ Rh3+ draws.
A very nice perpetual not so simple to spot for a human. It was found by Pachman
in the analysis of the game.
