S.phillips vs T Watson

Phillips has just played 1-6 ?! Tommy replied 22-17 to a draw...

While watching the game I thought that Tommy would have taken the winning 24-19 , after which 7-10 exchange goes down by 22-18 despite moves like 3-8 or 3-7 . And if after 24-19 black takes 3-7 white still plays 22-18 and black can choose to walk into a 2 fr 1 after 13-17 or have the man squeezed again.

White to play and win

john McElhone as i have stated elsewhere left me feeling hopeful about the future of checkers.

In our first game the following position arose with black , McElhone , to play .

Earlier in the game black sacrificed a piece for a breakthrough and kingrow .

Now he must pick up if he wants to draw .

McElhone chose 2-7 to my disapointment and I agreed a draw .

I had been hoping that he might think of letting let me exchange 9-6 , then take the 2 fr 1 to draw via 31-27 17-13 27-23 9-6 x x 5-9 etc.

However this would be wrong as I had been planning a neat lockbreaker win as follows ; 31-27 ?? 17-13 27-23 10-6 !! 3-7 ( 2-7 then cut is only 2 fr 2 and still a man up) 6-1 7-10 14x7 2x11 18-14 23-18 30-25 ! 11-16 1-6 16-19 6-2 19-23 25-21 23-26 21-17 26-30 9-6 18x9 6-1 white wins

In my first game against watson Luck was on my side!!

I was in PP loss , then Tommy (white) drifted to give me draw , but seemed at an important point of game to overestimate his bridge , and instead of running 21 down for a 9-6 cut to draw , he let me seize the endgame parameter men 30 and 21!! leading to following position ;

Black to play



Then followed ; 3-7 9-5 12-16 20x11 7x16 5-9 16-19 9-14 19-24 14-10 24-27 ( not too quickly for the switch of hold!! by 22-18 ) 32-28 22-18 (now!) 28-24 27-31 24-20 31-27 20-16 27-24 16-11 24-19 11-8 Forms the following

Black to play



23-27 8-3 ( 8-4 goes down quickly ) 18-15 !! ( now time to switch parameters for the win! ) 10-14 2-7 3x10 15x6 30-26 27-31 26-22 19-16 !! 14-18 31-27 18-15 27-24 ! 22-17 24-20 ! ( forcing the king move to get the space ) 15-18 16-11 17-13 20-16 18-14 11-7 14-9 7-2 9-5 6-1 5-9 16-11 9-14 11-15 14-915-18 21-17 1-5 9-6 x x 5-9 Black wins

I have not put these positions into database to check 100% that they win but during game analysis I could not define a draw for Tommy.

I will post a few more Endgames like this I had in ty. later , then leave space hopefully for others to add more

Lucky Shane ! See diagram #1 before 6-9?

#1. Red to move and win

5-9!!!

Fantastic position ... haven't seen such beauties for long time. Instead 6-9 which only leads to draw, red had a chance to score a wonderful win. See diagram #2 after 5-9, 19-16, 15-18, 22x15, 10x19, 24x15, 11x18. White have a man up and ... game down !

Delicious

Shane, very nice play and the whole position is wonderful. I would recommend you to publish it in regular media.

[william]

At the point where you play 27-24 ( first diagram) Shane , you remember That I pointed out after the game that you should have played 16-11 , exchange , then if your game is not a win then his position is at least severly broken .

Still though , what a fabulous crossboard sortie !!

I will post some later

shane

you should put the game that you win against me , with that analysis on 7-11 to draw

Cheers

Here is a position that came up in my game against B. Dobbins ( black )



In this position I was hoping to get the Allen win , and not the Lucas draw !! But that would depend on what my opponent was going to play!!

With black to play , he should go 25-30 6-2 8-11 to the Lucas draw ( Std Position ). And definately NOT 25-30 6-2 7-11?? ( The Allen win ) A standard position that should be known by everyone ...



Because then follows 31-26 ( 2-7 11-15 etc. and black collects his man ) 13-17 2-6 17-21 6-9 21-25 9-13 25-29 13-17 29-25 17-21 25-29 26-22 !! 29-25 ( 30-26 goes down ) 23-18 !! 25-29 18-15 11x25 20-16 White wins

When my opponent however played 25-29 I had to work up a different plan to threaten the man on 8 ... So played on this way 6-2 7-10 2-6 10-14 19-15 29-25 23-19 25-22 15-10 14-17 10-7 22-18 , and the first phase of plan has been acomplished in a rather logical sort of way
Forming the following;

White to play



6-9 ( start of second phase ) 17-21 7-2 21-25 2-6 25-29 6-1 29-25 1-5 18-22 ( has to go ) 9-14 25-30 19-15 30-25 31-27 25-21 27-24 22-17?? ( error but perhaps not fatal ) 24-19 17x10 15x6 21-17 ?? ( game over now )5-9 17-22 14-18 8-11 6-2 White wins

Oldbury in his ency. repeatedly emphesised the importance of knowing and understanding certain key parameters and endgames and Bill could have saved himself a lot of trouble if he had only known the Lucas draw. I do not say that by playing 25-29 was a total loss , but it left certainly a lot of " meat " on the table , of the type that Oldbury loved to play !!!

[Alex_Moiseyev]

William, according Kingsrow verdict - you both played very kind to each other He missed a draw by playing losing 7-10? instead 8-11* and later you missed a win by playing 19-15? instead 6-9*. However, if you read Sixth you should know - it is not important who made mistake first, it's important who made last mistake !

Although, access to program is not always available in playing room

Regards,

Alex

[william]

Hi Alex ,

Thanks for that info ... I guess that 8-11 instead of 7-10 goes back into the Lucas draw as mentioned above . But what is curious is you say Kingsrow gives 6-9 before 19-15 ? Is that correct? I will check it out , txs again

WILLIAM

[william]

Kingsrow has just shown the win to me on 6-9 instead of my 19-15 in Dobbins game .

I remember during game giving a quick calculation on the kingsrow variation but must have let slip by the 14-18 move after 29-25 , and only saw 2 fr one threat ??? !!! . This is certainly a convincing variation to be added to the Allen win / Lucas draw ( if an opponent should ever take that 7-10 loss ) A good one to know !!

[Alex_Moiseyev]

Yup ... 6-9 is a good win hard to find X-aboard and easy to miss. It's always better (like in this case) be aware and knowladgable of something rather than trying to find it under real time pressure. Knowledges are power ! This position may happened when red man is ALREADY on 10.
