I agreed with you; exchanging the Queens only helps black because it releases the pressure on their King and it leave us with doubled-isolated pawns, which is not the best pawn structure :/

Qf5 voters are still winning right now because of the rule to break a tie:(

Well, after 25.h6 cxd5 26.Nxd5, menacing 27.Nxf6+ (forking King and Queen);


Rxf6 counters that

and even if 26.Nxd5 Nxe4 27.Nxe4 Qxe4+ 28.Ka1 and that's all the attack for white

It's a Mate in 3 from there! 28. Ka1 Qd4+ etc

If instead 28.Kc1 Nd3+ should be winning for black too

f3: 1 vote (GoldTiger69)
Qf5: 3 votes (languagehasmeaning, tifozi, boolberry)

I just check it again, and I found that if 28.Kc1 Nd3+ 29.Kb1 Nxf2+ forces Queens exchange, but not much after that. But we would be 2 pawns down.

If black does that, then 28.Qxg5+ wins the Rook; unless they try 28... Kf7 29.Qg7+ Qxg7 30.Rxg7+ with a good chances for Queening (or winning the Rook on a8).

You're right, I just realize of that, thanks.

h6: 1 vote (GoldTiger69)

What is the planned follow up to h6? I looked at Qf5 and f3 because it is hard to activate either knight without dealing with e4 first. I am worried about 25.h6 cxd5 26.cxd5 b5 which looks precarious for us.

h6: 1 vote (GoldTiger69)

As we can see, the only piece defending good the black King is the pawn on f6. If we remove that defender, the game is ours.
So, I think h6 is way to good move, because it give us a mayor pivot point to make our definitive attack.

Edit: I just realize of my mistake on thinking that after 28.Ka1 that would be all. Now I see that black could do 28... Qd4+ leading to mate in the next move. And 28.Kc1 doesn't work either because of 28... Nd3+ with the possibility of winning the Queen in the next move.

Edit2: I'm wrong again; after 28...Nd3+, black doesn't wins the Queen if 29.Kb1; but then it would be a Queens exchange. So, after all, h6 wasn't that bad.

But I don't like Qf5 because of the resulting double pawn. So I'll change my vote to:

This seems like an important moment in the game. I need more time to think about some possible plans.

Agreed. This is like Part 2 of the game starting here. I think we can try to further simplify by exchanging queens and knights? Our e pawn seems to be in a bit of a pickle and I think Black obviously prefers opening the b file to c file for their attack.

Based on the votes in this thread Team Monero has chosen to play c6. Now it is time for Team Boolberry to respond. I will plan to count votes again tomorrow at approximately 0:00 UTC.

Came across this wonderful whitepaper today from some retweets http://eprint.iacr.org/2015/464.pdf

Great job explaining Bitcoin and crypto with more simplified math and illustrations. It mentions several other cryptos while devoting a section to CryptoNote and Ring Signatures (mentioning Bytecoin as reference implementation). It doesn't mention anything about Monero or the papers written over at MRL, RingCT etc but I guess they wanted to take the non-controversial route wrt CryptoNote whitepaper.

In other non-academic research, our Anonymous GM friend is a Cricket fan as well. Kinda narrows it down  Tongue



It is nice to see more academics studying CryptoNote even if they are not referencing the latest work from MRL.
