17...Qa4 may lead to draw.
18.Rg3+ Kh8 19.Qh6(I do not like 0-0 because of Qd4+) Rf7 20.0-0 and now
Junior's line after a long time show 0.00
20....Qe4 21.Bh5 Qc4 22.Bxf7 Bc5+ 23.Rf2 Bxf2+ 24.Kxf2 Qxc2+ with a perpetual
check.
I think every good player will not play Qxa2 because the queen has nothing to do
there and it is a bad idea to sacrifice the queen's place for a pawn.
I do not know if Qa4 save the game but it seem to be better than Qxa2.
What is the opinion of tal about it?
