(m)=my commnets/qusetions (s)=answers (c.s.)=computer says

7th

(m)I moved 46-41. Is it good to leave my leftwing ? What is good when I move in my leftwing ? 31-27
(s)Yes, you should have left your left wing. After 46-41, 21-26 is a strong move, as you cannot develop your left wing easily. Much better is to leave it like it is, don't even play 31-27, and play on your right wing (e.g. 35-30x29!), until it is the right moment to play 32-28! and 37-32

11th

(m)27-22 is good(=c.s.).
(s)Yes, but it is way to early to do so. Much better is to wait, as you did. Always wait, never attack before you have a solid and strong position. You did well.

13th

(m)I thought 28x17 12x21 is not good. White became locked.
(s)Yes, I think so too. You lost 2 more tempi, but you have more freedom and a stronger centre than your opponent now.

16th

(m)c.s. 32-28( for 37-32, 32x41) is good. But I think leftwing had developed and it was good to develop in my right wing. How about it?
(s)You decided well. Your left wing is perfectly developed (no pieces on 41 and 46), and what you should do now is focus on your right wing. After 16.50-44 you played 32-28, but you can wait even more by playing 40-34, 44-40 and maybe even 49-44. Always wait, than decide.

24th

(m)White mistook.
(s)Yes, is a pity, because you had won strategically: black had been forced to move to 30, and you have all the centre. After 30-35, which will come at one time, you win 6 tempi.

33th

(m)B23-29 33x24 B15-20 24x15 B19-23 28x19 B 13x44 is good. W15 can't go to 4 or 5 because W15-10 B9-14 B10x19 W3-9.But B44 can become DAM.

35th
(m)White got one piece back.

41th
(m)I got 24 and 17. White controled center.

44th

(m)28-22 is good. 22 can control center.

47th
(m)24-20 is good. Make dam faster.

(s)48. You played 24-20, but way better is to play 28-23, and after that 23-19, 15-10. Reason is that the piece on 14 ends up on 23, and you can try to eat it by getting dam at 4 or 5. The piece on 25 can never be eaten. Is important.
(m)I don't know it. It is important in endgame. When you notice my other weakpoints in endgame, please point out.

53th

(m)31-42, 42-33 is good

(m)I lost
(s)Yes, you lost. But you played very well in the beginning (except for 46-41), and after you lost one piece you kept playing. Note that after you regained your piece, you had more tempi than your opponent. Having tempi is very important, as you put pressure on the other. More tempi often means a better position. Let your pieces go forward altogether, always.

about how I study draughts.

I have bought DamMentor.
I analyzed it.
I have made the following tools(1-4).

1. Problem diagrams and answers books.
- I translate Dutch in dammentor to English , using google translator.


2. DamMentor ( English version )
- I can't read Dutch. So I have made.
- Google translate makes undestand-able english.
- It became more easier to use and understand.


3. PDN files
- I made these from Daiagrams of 1.
- When I can't understand the problem's ansewer of DamMentor. I use Dragon Draughts - Draughts program. It can analyze moves. It helps me understand or find the wrong answer of DamMentor.


4. Flash Card Pictures of DamMentor problems.
- I made the pictures of daiagrams and answers from Tweegevers, Van der Wal, Wiersma, Sijbrands and Rozenberg modules. 6,750 problems.
- I store the flash card pictures in my Android mobile. I can stduy them any time, any place.






And I use dragon draughts to study.

5. Note that I analyze the problems that I could not solve.
- I analyze the problems that I could not solve.
- Draughts program - Dragon Draughts - eats the pdn ,analyzes and estimates moves of the problems. So I can understand better.
- I write points for solving the problems on my notes.


6. Note that I analyze games I played.
- I analyze my games by using Dragon Draughts.
- It is very helpful for me to understand my bad moves.
