Today I am going to make some of you endgame lovers lottery millionaires.

1. The number of people at you club that will be actually
interested when you say you have an endgame to show them.

2. The number of times you will actually have to mate someone with a Bishop and Knight.

15. The number of Rook endings you have lost this year.

27. The number of dandruff shampoos you have tried without success.

36. The number of Endgame books (which all basically say the same thing) you own.

44 The number of books on the Endgame you will own after your next birthday.

Good luck, let me know how you got on (and don’t forget who gave you the numbers.)

Having kicked off by insulting all the endgame aficionados I now make amends.

We start with a neat wee study. White to play and win. It’s by M. Gruenfeld 1903.

1. Ra3 {This is the only move that wins.} 1... Kxa3 {If 1...b4 2.

Ka1 10. Qc2 {A pattern worth knowing.} 10... a2 {Only move.} 11. Qc1 {Checkmate.}

We go into this ending a wee bitty deeper because it often gets screwed up.
Quite a few RHP examples but I’ll show just some with the Black a-pawn.

Casey3 - wayne foote RHP.2017 (White to play)
White drew this. The win is fairly straight forward but it must be known.

Ka3 6. Qa5+ Kb2 7. Qb4+ Ka2 8. Kc2 {...and wins. If 8...Qc3+ do not play 9. Qxc3 that is Stalemate.}

Another recent example of an RHP player tripping up in this ending.

Next White tries a Skewer to win a Black Queen but it was not the way to go.

Brazuca - mallys7 RHP 2011

I’m giving White five out for ten for trying the trap. But they should have won.

One last piece of analysis with an idea in it my Mum wants you to see.

1. Kf2 {Only this move or 1.Kf1 wins.} 1... a2 {Do not promote, that is stalemate.} 2. Ke2 {Now White promotes with a check.} 2... Kb1 3. b8=Q+ Ka1 {Now what? We shall look at 3...Kc2 in the next game.} 4. Qh2 {The idea I wanted you to see and store.} 4... Kb2 {4..Kb1 5.Kc3 with mate on c2 if Black takes a Queen. A simple win if Black takes to a Knight.} 5. Kd3+ {5....Kb1 6.Qc2+ and Qc1 mate. or 5...Ka1 6.Kc3 mate next move.} 5... Ka3 6. Qd6+ {If now 6...Kb2 7.Qb4+ Ka1 8.Qd2.and Qc2+ and Qc1 mate.} 6...

One more variation to show just to clear up a loose end.

I have showed a few RHP games featuring this trick before, here another two.

White played 29.Rxb7 0-0-0+ . So much for the rule of thumb about castling early.

Here is the other 2018 game featuring castles with a check pocketing a Rook.

Leave them alone. 12...Bb7 and Black is doing OK.} 13. Bxa7 Rxb2 {Black could not resist it.} 14. O-O-O+ {White then took on b2 and it was soon 1-0.}
