Novag Constellation peculiarity

Post by Larry »

[fen]B1b4r/P4n2/5N2/5R1Q/7K/q4p2/p2Bpnpp/3RNk1r[/fen]

White to move, mate in 7:
Novag Constellation 2mhz 56 seconds
Novag Constellation 3.6mhz ~15 minutes
This leads me to wonder if there is more than just an 80% overclock
for the '3.6', but also other parameter adjustments.

Very peculiar indeed Larry. For the posted position after 1.Ra1..Bxf5 or 1.Qxh8..exd1=Q, Black has an easy win. Would be interested to see the M7! I'm guessing wrong position posted?

Hi Peter, the position is posted correctly, odd as it seems. Chess
programmers put checks up front of the list of moves to be considered
first. If there is only one reply to the check, then another check may
come, to which there is again only one reply, etc..etc...
That is the case here, and it is why even a humble Fidelity Septennial
can solve in a little under three minutes. Star Diamond, Atlanta and Co.
solve it in a heartbeat.
Here it is:
1 Nxc6 ch....Nxd8
2Nxa7 dbl ch...Kb8
3 Rc8ch Kxa7
4 Nb5ch Bxb5
5 Bc5ch b6
6 Kxb5ch Rxa4
7 Rxa8 mate

pretty neat stuff... :wink:

The Fen position might be posted wrong?
seems black is moving up the board evidenced by the rank and files reversed
hence Peters exd1=Q

Fidelity CC1 Regards

I was puzzled with Peter's exd1 = Q, now I know why. :oops:
Ignore the rank and file designations....white is playing up the board.
Then the diagram makes sense.

On the subject of making FEN diagrams, I've been having a small
problem. In placing the pieces, I was starting from the top left and
entering the pieces just as we read the page of a book ie, left to right,
top to bottom. I found that the diagram was inverting itself, ie, it
had black playing up the board. My solution to the problem was to
start entering pieces right to left, bottom to top. That way the diagram
showed itself the way I wanted, but the rank and file designations were
around the wrong way. This is what happened to my FEN diagram in
this thread.
Could someone please respond and tell me how they enter a FEN
position in a way that makes it come out right?
thanks...Larry

this is the correct fen notation to show white from bottom

r1kNR3/ppnpB2p/2p4q/K7/Q1R5/2N5/2n4P/r4b1B w - - 0 1


[fen]r1kNR3/ppnpB2p/2p4q/K7/Q1R5/2N5/2n4P/r4b1B w - - 0 1[/fen]

this was your fen notation

B1b4r/P4n2/5N2/5R1Q/7K/q4p2/p2Bpnpp/3RNk1r

if you compare the two i think you have the notation listed in reverse order

mine..
r1kNR3...this appears first

yours ..this appears last as 3RNk1r

Dyslexic Regards
:P

Thanks Steve, I'll get it right yet.
The position itself is fairly obviously composed, and is found in
the owner's manual for the USCF or Septennial.

I should have spotted that too. Thought it strange to have coordinates reversed.

Best regards,
Peter
