3.c4 shouldn't have a question mark; it's also drawing (probably the dual JMRW meant last week).

Sorry, I meant the variation 3.Kc5 (that ends with 5.c4).

Yes, @2

Nobody enjoys this section.

@Polizei
I enjoy it ! :)

"Nobody enjoys this section." , Except me.

I really enjoy this section, but I find the problems often to difficult to give a good contribution in comments.

Polizei. What a stupid comment ! If you dont enjoy it leave ! And let a lot of other people enjoy this fantastic section without such stupid comments ! I like this section a lot and I know a lot of people who do as well. Thanks a lot to Y Afek !

I like this section and I'm an amateur . . .

Thoughts so far: Nxe5, and after Bg3, Kd6. There could follow h1=Q, c7, Bxe5, Kxe5, and that's as far as I care to go with all the mistakes in my thinking. Just initial thoughts . . . another idea I like is Nb8, protecting the pawn a third time and getting ready to safeguard the king from the queen that will appear on h1, but then it's not clear how to get the king out of the way so the c pawn can queen.

By no means full analysis:

1. Kb8

a) 1... Kxc6 2. Nxe5+ Kd6 3. Bc6 and the pawn can't queen.

b) 1... e4 2. c7 Bg3 3. Ne5+ Kb6 4. c8N+ (4. c8=Q Bxe5+ 5. Ka8 a8=Q+ and mates) Kc5 5. Bc6 Bxe5+ 6. Kb7 Probably the most beautiful line.

c) 1... a8=Q 2. c7 e4 3. c8=Q Bg3+ 4. Ne5+ Kb6 5. Qd8+ I think draws too. This line I didn't analyse fully.

d) 1... Ba5 2. Nb6 Bxb6 3. c7+

@Alexander:

1.Kb8 Ba5 2.Nb6? Kb6 3.c7 Bd6 is winning for black

@Alexander:

1.Kb8 Ba5 2.Nb6 is a blunder Kb6 3.c7 Bb4 is winning for black
