PHILIDOR'S DEFENCE
(The) Side Variation refuting Legall's Mate
White's KKtxKP left his queen deliberately en prise.
Black develops his King's Bishop to K2(e7) to avoid Legall's Mate (the vacated square giving his king an escape if 6.BxP+ch), but 6.QxB..PxKt will gain White a pawn and better development. B-Alt.
    White  Black	White  Black

 3. B-B4   P-KKt3?!
 4. Kt-B3  B-Kt5?!  Alt.route (Bish.O.)
