Black has a really annoying pawn! 

The best line is the one with the elegant mate net with Bishop, King and pawns!

Excellent tactics and combination. Just brilliant. Thank you very much.

The most annoying pawn, for me, was the one on e5 😂

Very neat, cunning play, even ;)

Nice puzzle, thank you.

A very interesting and practical puzzle to help one’s ability to calculate . Unlike many other composed problems this one is very game-like which increases its value for study purposes.

"We can win this." First move, Bxe5. My pawns are patriots and they will give themselves up at my command

Many variations, enjoyed.

It looks difficult, so I had you show it to me straight away.

Uhmmmm.... @11:47, the king is NOT forced to b4. a4 is a MUCH better move, as it allows black to continue to run his pawn after whatever move white does. Should white move his bishop to b6, then d4, black just moves king to b4, threatening white's pawn, and white is in trouble (black's pawn would be at a2 at this time). Perhaps I missed something?

11:35 i rather think black will move with king to b4 here. His pawn is safe and he will for sure get whites pawn no matter what white plays. Also it would be interresting to see the outcome of the game while black king moves down the c and b line on the white fields to create additional pressure on d2 also while on b3 with the king moving the a-pawn.

Variation near the end with pawn C4, what happens if black takes whites pawn en passant, winding up on C2?

I think the best opening move here is c2 to c4 followed by b4-b5. am I missing something?

11:98 What happens if BLACK captures the pawn "en passant" instead of taking it with the king? You covered everything else. OOOPS ... just seen it's been answered below.

5:50 After that, if white takes the pawn, black will take d2 pawn and not allow white pawn to promote. Pawn + bishop cannot win against pawn.

My first concern is how that pawn ended up at that place to start with.

very good

What would happen if E5 moves to D6 for the first move ?

1 c4 dxc3 ep 2 dxc3 a3 3 c4 a2 4 Bf6 a1 = Q 5 Be7 and I don't see an easy way to stop checkmate.
