Pro Deo 1.1 Vulcan {9k10i} would have gobbled up the pawn too, but prefers to do
that with the Knight. No deep strategic considerations I suppose, and I think
Black is taking some chances taking the pawn right now. The White King is
sitting comfortably in his castle warming his feet at the fire, sipping some
good Spanish wine perhaps while his colleague from the other side is rather in
the cold, no matter whether he stays in the center or moves to his left castle
or his right castle.. After 15 minutes the evaluation is already not equal
anymore. Qc3xe5 is number thirteen on the list by then. But I guess your point
is that Kasparov's play against Anand is not exactly refuted by Fruit's opening,
but Black deviates just in time here from the 1992 game... I have not checked
what Vulcan would play confronted with Qxe5!?
