Subject: Unable to improve alpha

Author: Stuart Cracraft

So at the root, in the opening position, I play e4.
At the third ply of iterative deepening, the program
hits the position after 1 e4, e5; 2 Qh5, Bc5; 3 Qxe5. No
null move has been played here due to being in check.
The program now cycles through the only legal black
replies of 3 ... Ne7, 3 ... Be7, 3 ... Kf8, and 3 ... Qe7.
Going into this, alpha is -6 from the previous position.
None of these moves improves alpha and this value is
returned with no best move stored in the hash table.

My question is: is this a problem or expected given
the position?
