Of course being a dutchman too like timman i don't want to give

DIEP picks rd4 at 4 ply already and keeps it. however score ain't
draw score. I hope you could show me how you draw after rd2. i have
a +1.2 score white up after rd2.

On the other hand however, Rab8 definitely is a pure blunder. Jan is
getting a bit older now, but in reality Jan is showing how a western
GM played from the previous generation.

In the days that Jan Timman was young, he was a brilliant player, but
in west-europe, in contradiction to the countries behind the iron curtain,
they were not training their pupils in tactical skills very well.

So where Jan Timman, had he been born as a russian, would have been a sure
world champion, simply because his only weakness - making now and then
a slip of the finger.

Because imagine how this grandmaster, not so long ago number 2
on the FIDE ratinglist, and even counting short+kasparov who were
not having a fide rating at that moment, Jan still was number 4.

Imagine his playing strength without slip of the fingers!
