It's only my opening taste but don't find the e6, d6 alapin sicilian of Marc Esserman vs. Viswanathan Anand very easy. Prefer going into French type positions 1e4 c5 2c3 e6 3d4 d5, not sure what playing against the Morra gambit.
Aagaard is very keen on the line, and Kotronias develops the line further in his anti-sicilian book. Think both prefer 10...Qc7 of Anand game, compared to 10...Qa5 but the positions are quire similar.
Back in the day, i played many Smith Morra Gambit games and did well.
But that was about 50 years ago.
My guess now is that the Smith Morra is not sound.
