So far, I have made it through the King and Pawn endings as well as the Rook and Pawn endings. I thought I knew the Lucena Position (building the bridge) until I ran into the last few frames of the R+P+K vs R+K
The position of the defending King and how far the Rook is can turn this position into a draw ( depending on who's move it is).
A look at position 45 :
White to move, its a straightforward win. 1.Rg1+ Kh8or7 2. Rg4 and on to the Lucena. But with Black to move, Black can draw with Perpetual check on the ranks. 1... Ra8 + 2. Kd7 Ra7+ and the king can't stray too far away from the pawn to go after the Rook.
If Black's rook were over one file, its a win either with white or Black to move. If the Black king were up one square, it makes 2.Rg4 problematic and harder to force the win. ( with the black king at g7, 1.Rg1+ Kh6 2. Re1 allows white to go after the the black rook when checked from the ranks.
I started to look at the middle game positions too. I set up my board and set my clock for 20 minutes and analyze strategies for both white and Black. I try to focus on my thought process I outlined in a previous post .
My goal for this year is simple. I plan to become "BlunderLess" instead of my notorious BlunderProne Moniker.
