Jitse Slump - Martijn van IJzendoorn 0-2 (5-4-2018)
In the second round of the Dutch championship 2018 Van IJzendoorn won a beautiful game against Slump.
This opening scheme is a bit uncommon. Black voluntarily accepts a corner piece on 25, but compensates for this with a clean development of his right wing.
Slump offers his opponent to play a fork lock, but Van IJzendoorn immediately rejects it. Indeed the conditions for a fork lock are far from ideal.
This move has far reaching consequences. It leaves white with a heavy left wing, and it will not be easy to get any grip on the ideally developed black right wing.
White has developed the left wing, but at the cost of two weak pieces on 26 and 21.
With a brilliant move Van IJzendoorn manages to create problems for his opponent. It reminds me a bit of Harm Wiersma when he was reigning the draughts world in the seventies.
This allows black to block the white right wing completely. Probably Slump didn't trust the consequences of ≡ 31.40-34 35-40!? 32.34x12 40x49, but after 33.12-8! 3x12 34.21-17 12x21 35.26x6 49-35 36.33-29! 13-19 37.41-36 it seems to be OK for white.
Van IJzendoorn brings the positional threat 23-29 into play, in order to completely obstruct the white right wing.
Now the circumstances for this move are much worse than a couple of moves ago. The best chance for survival was to hang into the situation with ≡ 34.28-22 23-29 35.26-21 3-8 36.21-17 1-6 37.37-31. Then black has several attractive plans, for example 20-25 38.33-28 8-13 39.39-33 30-34 or ≡ 8-13 38.22-18 13x22 39.17x28 11-17 40.32-27! 19-23 41.28x19 24x13 42.33x24 20x29 43.39-33, but in all cases there is still a lot to prove.
Most likely the white position is lost now.
