Also a Najdorf, but it features the ...Nf3+ sacrifice that became famous when Topalov played it against Svidler in San Luis, thus (if the dates and scores are correct):
1) Chepa and Ibarra played some years after, with again a victory for the Bulgarian.
2) Topa is not the one who played 16...Nf3+ for the first time in prof. recorded history, but Cheparinov, even if Ftanick gives it as a novelty for Topa in his CBM analysis.
I really don´t know anything for sure about this affair since I´m getting contradictory informations, and furthermore: what the fuss about ...Nf3+ in San Luis if it wasn´t a novelty? So any clarification on the matter will be highly welcome!
