1) As the Bh4 skewer is threatened, something to block the diagnol is the other option. 8. ... g5 seems best to me to start a pawn storm.
2) The counter attack 11. ... Bxe2 seems best. I did not calc. the desperatos, but 12. Qxe2 seems to lose to the simple Qe6 and the pinned Knight is lost.
3) There is always a possibility, however throughout the rest of the game, Black can not generate enough counterplay/piece activity to compensate for the Quenn.
first of all it looks like queen sacrifice wasn't necessary. but in spite of it opponent had fair enough chance to win? Here is the game link
