Sicilian Scheveningen Tabyia

The position below, White to move, appears after the following move :

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3a6 6. Be2 e6 7. a4 Nc6 8. Be3 Be7 9. O-O O-O 10. f4 Qc7 11. Kh1 Re8



Now, a standard way to play this position with White is develop along this scheme:
Bf3,Qd2,Nb3 and then g4-g5.

Intead, an interesting idea is to play 12 Bd3 !? leading to the following position.



The idea is to target the black king directly through d3-h7, with e4-e5 in mind. Usually Black plays Nb4-d3 to eliminate the White bishop but that is not always enough to equalize.

Tactical motifs and kibitzers

The following position appeared with Black to play


Black played 1..Qh4 !?
After this startling move from Black, how would play the position with White ?
a) Yuri, the russian expert, said " Russians always go forward. Therefore 2.Nb5 should be played".
b) Richard, the swiss guy said " Sometimes neutralizing the opponent is called for, therefore I'd play 2.Nf3".
c) Emily from Canada looked at the position and said " Obviously you guys are not practical. The Black queen is en prise, there 2 Bxh4 is the right move".
What would you do ?
