Chess Summer School Day 10. One of the most important aspects of pawn play is the idea of the breakthrough. Most players learn early on how to break through with White pawns lined up at a5,b5 and c5 and Black pawns at a7,b7 and c7 when White breaks through by 1.b6 and ends up queening a pawn. Real games can be a bit trickier. In this position, Black needs to be careful as White has a pawn ready to head down to queen. By counting, you can figure out how many moves you’ve got to queen your own pawn and win.
