New engine from Russia

[WinPooh]

On my computer it plays well with control 40 moves in 5 minutes, under Arena.

[Vempele]

It seems strong (3.5/6 against GambitFruit so far). It doesn't support Fischer time controls, so the Toga match is 1 sec/move and the other 60 moves/minute. Sherwin50.pgn used in both matches. Core 2 Duo T5600, Arena 1.99 beta 4. Default settings for all (that is, Strelka gets more hash because I was lazy. According to conventional wisdom, it shouldn't matter much, especially at these short time controls).

So far, Strelka has failed to recognize the following time formats under Arena:
1. Blitz Game / minutes
2. Base + increment
3. Fixed time per move

Odd. Fixed time is working just fine here (1.99 beta 4).

[Edit]

Stratch the result against Toga. Arena made them play the same position over and over. GRR.

[Another edit]

It doesn't understand underpromotions (Toga promoted to a knight and Strelka crashed)

[Marc MP]

My first impressions are that the engine is (very) strong tactically, but has (relatively) few knowledge - the eval seems materialistic.

It is currently 4/8 at 40/4 (PIV 2.0 equivalent) against Spike, CT 2007, Fruit 2.1 and ProDeo 1.2 . Impressive.

Hi all !

1.Can Strelka be used like UCI engine ?
2.If yes-do you have a good configuration file (wb2uci.eng) ?
3.I cann't set this engine like UCI
4.Thank you in advance !

Regards,
Sylwy

It is a Winboard engine.

You can use a Winboard engine as a UCI engine with WB2UCI.

The thing is real strong!!:

PIV 2.4, 40/3, 64M Hash, 12-moves book:

Strelka 1 vs 3 CT 2007
Strelka 2 vs 2 Fruit 2.1
Strelka 3 vs 1 Spike 1.2

(A bit more endgame knowledge would have netted Strelka at least 1 point more in these games)

Strelka/Glaurung @FIXED DEPTH 15 plies.

In case someone is curious: Dann's game was played with the new Glaurung, which he is kindly helping me to port to Windows.

Strelka seems very strong for a new engine, and I look forward to follow its future development.
