A while back we had a queen sacrifice from Oliver Dunne that was A la Morphy.
Oliver has submitted another game, for which many thanks, this time from a Heidenfeld match last weekend. And it’s another queen sacrifice! In the diagrammed position Oliver ventured 27. … Qxd6!!??, sacrificing the queen for two minor pieces.
Let’s set this up as a puzzle.
(a) is this sacrifice sound?
(b) if so, what’s the evaluation after this move?
(c) if not, is there anything better for Black, and how should White continue?
In the game, regardless of the answers to the questions above, White did not make the most of her chances (though Oliver notes that time pressure was a factor) and Black won a resounding victory. [Click to play through the full game.] So an extra question is
(d) where could White have improved?
