Blockading with Queen is quite Alright!!

I still vividly remember the clamoring middle aged gentleman speaking defiantly that a Queen is NOT A GOOD BLOCKADER while shopping at a Goichberg book store in Las Vegas(Bill Hook can verify). USA chess player Augusta must have known this loud mouth because he refused to play Qd6 blocking the advance, and discovered check, of White's d5 pawn.

Even International Master Arthur van de Oudeweetering seems to occasionally spread this dogma. Denis Khismatullin, a strong player, also seems to believe that not to blockade with the Lady is an absolute truth. 

I think both of these chess talents know there are concrete cases where Queen Blockading is a tactical necessity, BUT they still need to be careful about the language they use when teaching chess or annotating their games!!

Queen to d6 is the best move in the diagrammed position for the reason that White does not have any Horses left on the board!! Black is even a little better after the CORRECT BITCH BLOCKADING MOVE.
