Request: Best hard tactical test suite for engines

[perejaslav]

I need a test suite for chess engines to check their tactical abilities.
I tried WM-test but some positions looks like too easy for engines and some not tactical at all. Under 'tactical' I mean king attack foremost. For me tactical position is a middlegame pos. with the Queens on the board.
Anyone has such suite

Look at this one: http://www.talkchess.com/forum/viewtopi ... ght=berkes

Is it too easy given your computer power? I could gather some of this level of difficulties. The newest arasan.epd has very tough ones also. Do a serach with the key words "test position" on this forum, you might find a couple quite a bit hard. Lately Andrew R. Case came up with real challenges (and other people too).

To fully solve these problems, you must not only get the right move but also resolve to a mate score.

If (for instance) you get the key move right, but the score is negative or zero, then add zero points.

If (for instance) you get the key move right, but the score is an advantage of less than a full piece, the score is +1 for that position.

If (for instance) you get the key move right, but the score is an advantage of less than a queen, the score is +2 for that position.

If (for instance) you get the key move right, but the score is an advantage of less than a checkmate but more than a queen, give it +3 points.

If you get any checkmate score, then give it +4 points. Maximum score is 28 * 4 = 112 points.

Time is one minute per position.
