Challenging!

I got the idea pretty quickly, but even then there were so many variations I wasn't absolutely sure.

What made this puzzle easier today

was that it was amenable to exactly the same solution method as yesterday's hard puzzle:

puzzle #31939. I actually varied my method slightly in that I decided not to even think about queen moves unless I eliminated other possibilities, and this left bxa5, which fails to 1. ...Rb4!, and b5.

medium puzzle

harder than an usual easy puzzle with all the lines to consider. You can call it medium puzzle

I was lucky and got the right idea immediately.

It's true that there are many lines to consider, but it's also easy to see that almost any move by Black can be answered with 2. b4#.

The only exceptions are 1... Nd4 (2. Qe4#) and 1... Re4 (2. Qxd6#), since both moves would give Black an opporunity to block the white bishop's diagonal in the second move, as well as 1... dxc5 (2. Qc6#) which removes White's control of e4. But all of these give the white queen an opportunity to give the finishing blow.

Nice one!

Not interesting

A quick glimpse at the position allows to spot the awkwardly posed and useless bishop, and then to build on it...

The rook to e4 threw me off for a while… forgot the bishop traps the knight...

3 stars - nice

you just know it has to be the useless light-square bishop that is the key, and then you realize the d4 pawn has to get out of the way, and you KNOW that only one of two possible moves will work, and then you realize right away, if bxa5 instead of b5, black can block the discovered check-mate with Rb4. the other reason it has to be the bishop is all the other pieces are already where they need to be.

This was not easy.

This one took time. First I tried many other moves and at last tried to move pawns and that was it!
