Nice puzzle today......

uncommonly good composition - so many compositions involve moves that are completely counter-intuitive

nice one

not so good

Unless the person with the rook really knows what he/she is doing, then KQvKR is not too difficult. The defender doesn't need to know anything special for KBNvK, the attacker just has to know how to do it.

If the attacker and defender both know these endgames well, KBNvK is much preferred for the attacker over KQvKR.

nice very nice

EASY

Mighty fine.

nice one

Interesting

ok but too much sacrifice

Kxe5 is not right

Lots of wild comments today at least on the front.

Great puzzle

good

Good!!

good solution.

Kxe5 is not right

----------------------------

Black drops his rook if he takes the pawn, plus the diagonal barrier is set and the knight free to roam.

I don't know about that.  It's a 30+ move forced mate KNB v K and one slip by the stronger side will put them over the 50 move limit and get a draw.  KQ v KR is a little simpler though not much fun either.  All those deflections just for a QvR endgame/  *shiver*
