I asked you to guess how many pawns in the goldfish bowl.
The answer was (and Russ will confirm) 71 pawns and the winner
was Contenchess who came closest when he guessed at number 72.
Next for your instruction and entertainment we have this piece of art.
It was composed by K.A.L. Kubbel, USSR 1936
White to play and win.
Clue:
Sacrifice things.

[FEN "8/7p/4pK1k/5R2/8/1b2r1P1/8/5B2 w - - 0 1"] 1. Rf2 {Threatening Rh2 mate.} 1... Bd1 2. Rh2+ Bh5 3. Be2 {Threatening 4.Rxh5 mate.} 3... Rxe2 {The win with 3...Rf2 (next) is just as instructive.} 4. g4 {Threatening 5.Rxh5 mate.} 4... Rxh2 5. g5 {Checkmate.}
Before leaving this wonderful wee puzzle we can squeeze another idea tuck away inside it..
FEN
8/7p/4pK1k/5R2/8/1b2r1P1/8/5B2 w - - 0 1
[FEN "8/7p/4pK1k/5R2/8/1b2r1P1/8/5B2 w - - 0 1"] 1. Rf2 Bd1 2. Rh2+ Bh5 3. Be2 Rxe2 4. g4 {Instead of 4...Rxh2 we look at learn at...} 4... Rf2+ 5. Rxf2 Bxg4 {A Rook v a Bishop and two pawns if very often a draw. but here...} 6. Rh2+ Bh5 {Only move, now White picks up the e-pawn whilst keeping the Black King imprisoned.} 7. Rh3 {Not 7.Rh4 which would be a draw. White must time the move Rh4 just right.} 7... e5 {Now is the time for Rh4.} 8. Rh4 e4 9. Rxe4 {This way White picks up the pawn and the Black King is till stuck in the mud.} 9... Bd1 {It does not matter where this Bishop goes...} 10. Rh4+ {...after this it has to go back to where it came from.} 10... Bh5 {Careful, do not stalemate Black.}11. Kf5 {Black has only one legal move.} 11... Kg7 12. Rxh5 {Now it's a simple White win.}
As I said earlier, a Rook v Bishop and two pawns is usually drawn. Any
winning chances are usually with the Bishop and two pawns player.

[FEN "8/8/5R2/1pk5/5K1p/b7/8/8 w - - 0 56"] 56. Rf5+ {In the game White lost the Rook with Rh6 Bc1+ and 0-1.} 56... Kc4 57. Rxb5 {The easiest way to draw.} 57... Kxb5 58. Kg4 Be7 {And Black has the wrong Bishop for h1. A known draw since Noah floated the Ark.}
Red Hot Pawn players are losing drawn games by not realising that the wrong
Bishop for the Rooks pawn is a draw. Here is another example from last year.

I was strolling through RHP games looking for an idea and happened upon a good
one but before we see this game I’ll slip in a study by D. Joseph from BCM 1922.
White to play and win.
FEN
1k1K4/1p5P/1P6/8/8/8/p7/8 w - - 0 1
[FEN "1k1K4/1p5P/1P6/8/8/8/p7/8 w - - 0 1"] 1. h8=Q {The recurring White threat is discovering a checkmate by moving the King.} 1... a1=Q {If 2.Qxa1 then it is stalemate.} 2. Qg8 {Now we witness some crafty moves by White to get the Black King to a8.} 2... Qa2 {1f 3.Qxa2 then it is stalemate.} 3. Qe8 Qa4 {If 4.Qxa4 then it is stalemate.} 4. Qe5+ {White forces the King to a8 so the stalemate trick is removed.} 4... Ka8 5. Qh8 {Back to the original square with the original threat, a discovered checkmate.} 5... Qa1 {There is no other move and this no longer works because} 6. Qxa1+ {That is a check and it is checkmate next move.} 6... Kb8 7. Qa7 {I told you.}
So you get the defensive idea to watch out for a Queen sac allowing stalemate.
