Therefore, White should have tried 34.Qe5} 34... Bh1 {(?) According to my

weak and Ufim 3.02 has a deadly attack.} 35. Kf1 {(?) The last mistake in this

After move 33 the game was an easy win for Black. I made a special setting for TheKing
to continue for White. At that moment white should take advantage of his passed pawns(mypp set to 120),
protect its king that is open to attacks( myks=130), take some care of the opponent pawns
that are strong( oppp=110, oppw=110), take care about mobility and center control( =110),
don't care at all about opponent king safety who is well protected( opks=80) and dont care at all
about its pawn weakness since they cant be weaker than they are(mypw=80)
15 minutes were given to each engine to finish the game.
This is how the game continues after move 33. Around move 100 Ruffian( black) starts to
run out of time. The game at that moment looks like draw. At the end TheKing( white) wins.
The first move TheKing choses is the one Kurt would play.

Hi Dimitris
Thank you for your test. However, I think the position is too difficult and needs deeper analysis than 15 min for the rest of the game between tow computers to come to an final conclusion. I am absolutely sure, that the game was lost after 34.Qg5? but as mentioned in my comments the question remains open after 34.Qe5! I am going to analyse this continuation and shall report again.

This time I used 1 hour for the rest of the game and a special King setting to continue for Black. This setting I believe best understands the possition from blacks point of view. cc=110, mob=110, myks=90, opks=120, mypp=110, oppp=120, mypw=110, oppw=80.
For white I used the special setting that played against Ruffian.
This time it was an easy win for Black.

In the meantime I have studied the position after 34.Qe5 for about five hours was unable to find a win. My computer assisted me with 20 min/move. Anyway in the above variation there exists a considerable improvement:
34.Qe5 Bf5 35.c5 f6 36.Qe2 Qc6 37.Re1 [? that's a mistake, correct is 37.f3! Rxf3 38.Rf1! Rxf1 39.Qxf1 and I see no win for White] e5 38.f4 Rd4 39.Rf1

Hi Kurt,
I am not sure if 37.Re1 is a mistake. Following your variation is true that we stop the tension arround the king but on the other hand we lose the rook we needed to support our passed pawns. Perhaps in such a possition is better to play for a draw than for a win and you are right. On the other hand, the possition that arises after 37.f3 leaves black whith perfect pawn structure supported by the king. I dont see much white can do to stop black pawns. Except from a good placed but vulnerable king he has.
Here's a possible continuation of 37.f3 variation

67.Qd6+ Kb7 68.Qe5 Bd7 69.Qe7 Qg3+ 70.Kd1 0-1
A slow and stable win for black
