Sting-sf-6 a quasi-intelligent engine

[consen]

It was ZoneAlarm antivirus program that was the problem with setup Sting SF 6.0. I disabled the ZoneAlarm and it worked.

Thanks Marek Kwiatkowski for this fantastic chess engine.

I like chess Puzzle and Sting is the only chess engine I have found that is very good on that.

Thanks, I feel chess more than a game result and I hope a clear Elo-machine question is far to be important for people only.

Neither pv is convincing. The path to Kd8 initially got a high score, but then there were a series of fail lows and that idea was abandoned.

I think this position is probably drawn.

Because the enemy queen can move, it is not possible for force the enemy king to lose his block of the pawn.

Yes 1.Bh6 Bmove 2.Bg7 Bmove 3.Bxf6 is good too.
White has to play 3.Bxf6 to succeed in the test !

Neither pv is convincing. The path to Kd8 initially got a high score, but then there were a series of fail lows and that idea was abandoned.

I think this position is probably drawn.

Because the enemy queen can move, it is not possible for force the enemy king to lose his block of the pawn.

Left it running overnight unintentionally - about 7 plus hours
