Sep-29-21  Cheapo by the Dozen: <Brenin> nailed the essence.

Black has various ways to thrash around for a couple of extra moves in the 18 ... Rxb5 lines, which is why this is a Wednesday puzzle rather than a Tuesday one, but they wind up being immaterial -- eventually White's queen checks on the back rank with no useful interposition available, Black has to play ... Ke2, and White can respond with Rd7++.

Also, for completeness we can note that not capturing the bishop gets Black very quickly mated.

  Breunor: 18 Bb5 check is a beautiful move!
Sep-29-21  areknames: <18 Bb5 check is a beautiful move!> Yes! Happy to admit I didn't get this one, GM Stefansson obviously did.

  An Englishman: Good Evening: Black probably had to play 15...gxf6, a typical Richter-Rauzer pawn structure. If that fails, then Black might have some serious problems with the entire variation.

  al wazir: Black is threatening 18...Qxb2#, 18...Rxd6, and 18...Bxc3, so the first move has to be a check. That's the only way to avoid mate or loss of material.

The only one available that doesn't make things even worse is 18. Bb5+.

  FSR: Easy to find if you know it's there. Always examine checks, captures, and threats . . .
Sep-29-21  stacase: My long gone brother always said, "Look for one of your pieces that isn't doing his job!" Yes, what is that useless Bishop doing still sitting at home?"

As always I accept my opponent's resignation, even when it's a surprise (-:

Sep-29-21  saturn2: 18.Bb5 deals with the threats Qb2, Bxc3, Rxd6

  raymondhow: 18.Bb5+ is a cute move, didn't take too long to find since black's mate threat limited the options.

  agb2002: White has a bishop, a knight and a pawn for the bishop pair.

Black threatens Qxb2# and Q(R)xd6.

The rook on b6 protects the queen. Hence, 18.Bb5+:

A) 18... Rxb5 19.Qc6+ (19.Nxb5 Qxb5)

A.1) 19... Kf8 20.Qxc8+ and mate next.

A.2) 19... Bd7 20.Qxd7+ Kf8 21.Qc8+ transposes to A.1.

A.3) 19... Ke7 20.Qc7+ as above.

B) 18... Qxb5 19.Nxb5 Rxd6 20.Nxd6+ Ke7 (20... Kd7(8) 21.Nxf7+ wins decisive material; 20... Kf8 21.Nxc8 wins a rook) 21.Nxc8+ Rxc8 22.e5 Bh4 23.g3 wins decisive material.

C) 18... axb5 19.Qxb4, etc.

  Teyss: Aaahhh a clear checking-interfering sacrifice, not a wee petty mushy-mushy Queen move like yesterday.

Quite straightforward. In the main line 20.Nxd6 is enough to win but if you figured out the follow-up as <Brenin> and <agb2002> did it's better.

  Dionysius1: I like how White can end up a whole R to the good after 19…Qxb5 20.Nxb5 Rxd6 21.Nxd6+ Ke7 22.Nxc8 Rxc8 23.e5 Bh4 24.g3
Sep-29-21  Stanco: I solved it, lovely one!
18.Bb5+!
18....axb5 19.Qxb4
or mate if 18...Rxb5 (19 Qc6+ Bd7 20 Qxd7+ Kf8 21 Qc8+ Ke7 22.Rd7#

  Once: This is one of those "surely this doesn't work, does it?" moves. That's when you find a move because it works in one variation, then you discover that it works in all other variations too.

Maybe you got here by examining every check.

Maybe you wanted to block Black's mate threat on b2.

Maybe you spotted that the black king had no moves and only needed one check to end his days.

Perhaps it doesn't matter so much how we start the journey - it's how it ends.

I wonder if white stared at this position for a long time, channelling his inner agb2002 as he worked his way methodically through the variations. Meanwhile black would start to get suspicious. What's taking him so long?

Then when white thumped down 18. Bb5+! black would have thought ... "surely that doesn't work, does it?"

Sep-29-21  Cellist: I saw the decisive move quickly, but then it took me longer to figure out Black's possible answers. Three ways of taking the B, all bad... I am surprised nobody has made a pun yet about the tournament name (Lost Boys Open). Black's pieces on the Q side certainly look like "lost boys," although they include the Q.

  Teyss: <Once: (...) inner agb2002>. This word should make it in the dictionary along with McAdam and Sandwich.
For some of us our agb2002 is very very inner and secluded.

  Check It Out: Doing this blind again, I looked at forcing checks with the queen on the d line for awhile, but blacks bishop have it covered.

On to the next forcing move, 18.Bb5+. Black retakes with 18...Rxb5 19.Nxb5 Qxb5 and here i thought, white's down a rook and pawn for blacks two bisthops, which could be quite dangerous.

Then I noticed that blacks DSB, could be trapped with 20.e5, and it will have to give itself up for a pawn. White up an exchange, looks good.

Sep-29-21  Stanco: <Check It Out> too bad 19.Nxb5 is followed with 19...Qxb2 mate lol 🎃🎃🎃 🍻
Sep-29-21  johnnydeep: I actually saw this pretty bishop move in short order. Perhaps I don't suck as much as I think. (Nah, who am I kidding?)

  Check It Out: <Stanco> I was blind to that bishop! <Brenin>'s lines make a lot more sense.
Sep-29-21  Stanco: The brackets wall it all off, discard them and put more into confidence next time ☝️
Sep-29-21  landshark: It had to be the easiest puzzle so far this week - It's the first one I got right!
