Considering the above record, and the following one...
The ce jumps from -31 to +68 so not choosing e6 seems harmful. A long analysis along with database examination will give a good answer about that.

Considering the above record and the following record, the ce jumps to over a pawn. I suggest that the transition between the previous record and the following one be studied carefully.

Here, Be7 is the move to be played. The queen move loses, period, and it should not be in any chess opening book unless it is a purposeful blunder book. From the following record forward, we are toast.
