And +25€

I usually don't buy every version of an engine. I purchased Naum 4 only because Alex said it is probably the last one. And if there would be an update it would be for free.

Now I would have to pay 25€ for an update from 4.1 to 4.2.

I'll drop this one...

Only 25€ for +50 elo !!!

Most programs offers less gain per euro.
i've paid 36€ for Deep Junior 11.1 and it's only 10-15 Elo stronger than Deep Junior 2010.

But they have at least a 'no-clone certificate'

well, paying 36 euros for a 15 elo increase & nothing else to offer is silly imo. note that he says 50 elo over naum 4. naum 4.1 is already +~25 elo over naum 4 last i heard. so if his estimate is correct it's a dollar per elo for original naum 4 customers. imo, a ripoff, compared to what new customers purchase it for. if the increase is 50 elo over naum 4.1 i understand the decision.

Also from the website:

Customers who bought Naum after the 4.1 upgrade will receive the 4.2 version for free.

I think that exactly is the case. i remember Alex once saying if he can boost more than 50 elo from Naum 4.2 it will not be a free update for naum 4 customers.... However customers who bought Naum 4.1<will get 4.2 version for free.

Hi,

After finishing my 64-bit improvements test results indicated bigger gain then what I expected from just a speed increase (probably result of changed move ordering).
I don't think it's a rip-off. Hopefully tests by CEGT/CCRL will prove me right.

I have to admit I feel a bit guilty since I didn't work very hard on this version, but I found out from 4.1 that sending an update to hundreds of customers is a lot of work and this will pay for my time and narrow the update base only to people who are still interested in the engine.

Next thing I plan to try are some of the Robbo ideas, so there may be another free update (or new pay version if ELO increase is big).

Regards,
Alex
