what was jdb's table conditions again? E+3 pieces vs E + 2 pieces, max? Or 3 pieces total vs 2 pieces total max?

It was 3 vs 3. Here's the thread:

If that it true, then I hope it is the two steps that immediately occurred to me when I saw the position.

I'm fairly certain I know which move your referring to, and I agree that it's the best move, but there seem to be other golds moves that don't give silver an obvious advantage also. I'm a little worried that it is gold that has a forced win because my mainline currently results in a gold advantage and I need to find an improvement for silver. Notice that it is silver who is in the predicament I described before, where two steps might not be enough to prove an initiative, after gold's first move.
 
@Fritz: Those two steps are hopefully the same two steps I immediately saw.

I'm not even sure that the move I previously thought as gold's best is actually gold's best. I think gold has several good first moves, or at least other moves that deserve attention. I'm fairly confident now in my ability to play this endgame. It might be against intuition, but I think strategy still dominates tactics. The tactics are too simple in my opinion to be a difficulty for humans. I did come up with an improvement for silver in my mainline. My most recent analysis again says the game is even, without a clear advantage for either side, but there are plenty of pitfalls both strategic and tactical. I'd like to play a non-official game with anybody that wants to play. I'm fairly confident that I understand the positions well enough that I can beat anybody, and perhaps anything. Of course if you also have done analysis that puts us on even ground, and I'm not so confident anymore Tongue

Apparently this is not the case, it's just that I can't see the tactics, and therefore get the impression that they are easy Tongue

Seems we agree on the move and browni still fails in disproving the statement.
 
I am going to investigate the following position:
1g Ra1 Rd1 Ef2 Rg2
1s ra7 rd8 ef7 rg7
2g Ra1n Ra2n Ra3n
2s rc8w
3g Ra4s Ra3s
3s rb8e

I agree now, it wasn't obvious to me before why another move was bad, but it is now. All moves except for Ra2n Ra3n lose for gold.

In near future my AEI will be able to start eee games.
I expect following interface:
As gold it looks for current last valid position in this threat and it offers to play this game, but if opponent complains, it would be ready to play position defined by opponent.
As silver it will look at the position as well and could wait for position defined by opponent, but it would allow "followmirror" and "followcentral" chat command in which case it will mimic gold till "start" chat command appears followed by at most two steps of gold.
Game could end on illegal move in this case when playing on opponent half.
 
Playing gold the bot would play fastest way to reach the eee position while not leaving piece further than on 2nd row after each step. There would be exception to this if it detects the opponent is not able to reach the eee position in time in which case it will wait.
 
Playing silver would mimic gold even on agreed position till the eee position appears.
 
Most of this is already codded ... it generates correct  gold setup sequence for current eee. ... So I hope in few weeks ... Smiley
