New release Revenge 2.0

[Rubinus]

Any advantage for version 1.0 holders?

I'm really sorry but the price is low for the time and resources invested, so there won't be a discount.

Since I'm making a collection of old specials, then it has to wait until at least January... I was just asking just in case.

I am pleased to announce a new version of my chess engine: Revenge 2.0

There are a lot of improvements compared to Revenge 1.0:
- New and bigger neural network
- Higher depth for history pruning
- Improved history move ordering
- Improved ProbCut
- Improved reduction formula
- Added uci option SyzygyProbeDepth
- Stronger MultiPV analisys
- Speed up neural network incremental update
- Speed up neural network calculation
- Some speed optimization in search
- Added in the package the executable for ARMv7 Linux

All these changes results in about +90 elo compared to Revenge 1.0 measured in selfplay at 1:00+0.5 time control.
With the new network the engine is stronger in all phases of the game especially in the endgame.

The engine is available for Windows x86_64, Linux x86_64, Linux ARMv8 and Linux ARMv7.

It is sold at the same price as the previous version: 19.99€

For buying the engine or getting more informations visit www.revengechess.com

Congrats for the release! That's a big progress from version 1.0

YES ... about 90 elo more

I have ELO around 2080. Revenge 1.0 has 3413 on CCRL, probably underestimated against FIDE. So that +90 is something like trying with your bare hand at a train station to see if the trolley voltage is 800 or 850V.

so ... after 6000 game s.... +91
