Considering that White has voluntarily immolated his rook...who really cares?

59. .... b6 looks obvious. Black will effectively playing two Rooks versus one (one White Rook being trapped on g5).

 

p.s. 59. ... b5 ia also a possibility. Some calculation is required, after all.

AndyClifton

Well, it's either that or ... b5 (lol)

Where can you buy a slominski jerry engine? The houdini is easy to find, but this one...

AndyClifton

Still, might be worth the effort (at least the Slominski keeps its rooks free).

The strength reduction is mostly based on a combination of two techniques:-protocol compliant version of Strength parameter.

Limiting the number of positions searched - this reduces mostly the tactical strength of the engine;
Purposely picking a move the engine knows is not optimal - this reduces mostly the positional strength of the engine.

The combination of the two produces a game with both tactical and strategic (positional) flaws.

 

The following table shows the estimated Elo of Houdini at reduced Strength levels. It is based on the feed-back of several users:

 

Strength  0 => 1200 Elo
Strength 10 => 1500 Elo
Strength 20 => 1800 Elo
Strength 30 => 2000 Elo
Strength 50 => 2300 Elo

 

What is the highest strength level that you can consistently beat?

 


UCI-protocol compliant version of Strength parameter.

Default 3000, min 1200, max 3000.

 

Internally the UCI_Elo value will be converted to a Strength value according to the table given above.

The UCI_Elo feature is controlled by the chess GUI, and usually doesn't appear in the configuration window.

 

UCI_LimitStrength (checkbox)

Activate the strength limit specified in the UCI_Elo parameter.

This feature is controlled by the chess GUI, and usually doesn't appear in the configuration window
