I guess that you tried to capture the pawns from the wrong side(you probably
tried to capture a7 first and it is a mistake and it is better to try to capture
a4 first and if thr opponent play a3 a4 a5 then you neeed to go with the king to
b5 and start capturing a4 a3 a4 a5 a6 a7 when only one move is no capture.
