Opposition: King Before Pawn
The kings are on the same file with two squares between them, e6 and e7. It is your move, so you can close the gap to one square and leave Black to move.
Win the endgames you keep letting slip.

Three ideas every endgame player needs
Straight from the course. Read the idea, then play it against a defender that never gives up.
Practice it
The Square of the Pawn
Start from the pawn and draw the diagonal up to its promotion rank: a4, b5, c6, d7, e8.
Rook Behind the Passed Pawn
Your rook on e1 stands behind your pawn and his rook on e8 in front of it. Keep yours there. Rd1? would be a mistake: Rd8+ hits your king and your rook, and after Kc6 Rxd1 the win is gone.
How it works
1
Learn the idea
A two-minute lesson on the one concept that decides the position: the opposition, the bridge, the third rank.
2
Beat perfect defense
Play it out. The opponent pushes its pawn to the last rank, sets traps, and never, ever gifts you the win.
3
Keep it forever
Positions you missed come back, mirrored and color-swapped, so you revisit the idea, not the squares.

Or face a human defense
With a free account, switch the opponent to a human defender of your level, from 1000 to 2000 Elo. It defends the way real players do, mistakes included, so you also train against the defense you will meet in your own games.
