How strong is Maverick 0.2?
Maverick 0.2 has been out a couple of days now. I’ve run some test games and I really quite surprised at how strong it seems to be.
The first test was against Fruit 1.0. I played this match using Shredder’s GUI. As I expected Fruit won. I really was dazzles by Fruit’s silky smooth search as it carved it ways through each ply (especially in the endgame).
- CCRL Rating = ???? (between 2300 and 2400)
- Time = 1 minute plus 1 second per move
- Result for Maverick: Wins = 24, Loses = 63, Draws = 13
- Percentage = 30.5%
- ELO Difference = -146
I was pleased with this result. However, it would seem Fruit’s strength is not well established. As far as I can tell it us somewhere between 2300 and 2400 ELO on the CCRL scale. This would put Maverick 0.2 between 2150 and 2250 ELO.
The second opponent was Phalanx XXIII. Another classic engine. As I watched them play it is clear Phalanx has much more knowledge than Maverick. Yet Maverick did well to win some game based on its speed.
- CCRL Rating = 2387
- Results for Maverick: Wins = 36, Loses = 49, Draws = 15,
- Percentage = 43.5%
- ELO Difference = -45
Once again I was pleased. Based on this result Maverick is over 2300 ELO, which is probably too high but let’s see.
And remember, at this stage Maverick is lacking some standard features:
- No mobility in the evaluation
- No passed pawn code
- No king safety
- No pawn structure code
- No late move reduction
- No Internal Iterative Deepening
- Lots of endgame evaluation missing
So I’m encouraged by Maverick’s strength. If you run any sort of ratings test I’d be interested in the results.
I will not release another version until it has gained 100 ELO. This may be some time.
