Nice. Thanks!
A recent pawn endgame
Nice endgame position @introuble2 I hardly ever play bullet, but I did find ...e4 almost instantly because I identified this type of pawn lever called a "chain lever."
I had better know it, I made a video on this lever and others just last month
a position from a recent bullet. I've found the winning move, but lost on time. However, I might have lost it further in the game, as it could become complicated.
Here in puzzle only the first move, as the next ones have alternative options...
... some analysis
