Too easy!

Pretty easy with K trapped in corner,all forced move's 1.Nb6+...axb6, 2.Ra5+...bxa5, 3Qxa5#.Thank's Chess.Com,good day chess head's.No what if's today.

Queen b6 is better second move, true if black donates both rooks and Queen they could drag out 4 more moves

1st.

Mate in three,all forced,why prolong it? Nice annalysis though,Thank's
