Grandmasterly moves
I selected a few random testpositions to see how the Search&Destroy 6_7e3
settings for Pro Deo would hold up. Tested in Analysis mode and sometimes went
to 18 ply to have have some reference material. I compared the lines and times
needed to get to a move that seems settled, for S&D 6_7e3, S&D 6_7, and default
Pro Deo 1.0 + adaptive nullmove (with [MISC_78], but not yet with [My Queen =
101], I just had not yet added that one).
All testing with Celeron 500 MHz, 28 Mb HT
First testposition is more or less my favourite testmove with Rebel, from the
Rebel versus Grandmaster matches. Grandmaster Rohde started a nice King Attack
against Rebel that inspired Ed to make some changes in Rebel's King Safety. My
idea was to see if Rebel when playing with the black pieces could have started a
similar attack. I did not really test lots of lines, there are many interesting
moments from this game but this move was fascinating as for Rebel it seemed
really a choice between two moves; Rohde's 22...Qb6-d8, a withdrawal of the
Queen to the eight rank and from there on into the center, or an invitation to
exchange Queens with 22...Qb6-a6

Second testposition is a fragment out of New in Chess magazine 2004/5.
Leko plays a new move in a bit suspect line of the Taimanov variation, 10.Kb1!
Pro Deo and company do not choose that move but go for an all-out pawn attack on
the Kingside, with 10.g2-g4 and even 11.h2-h4. It does seem playable to me as a
response to Anand's 9...Na5. That knight seems a bit lost on the edge, so why
not start an attack on the other wing as Black also does not have a good
position for him to castle longside. The black king has to remain in the centre,
castle into an attack or behind a weak pawn formation. I think 10.g2-g4 is a
playable find from the computers here.

Here Peter Leko played 10.Kb1. GM Sergey Shipov writes: "10.Kb1! A novelty! As
it transpired, this is the most accurate move order. For the moment White leaves
his d4 knight in place and creates the threat of Nc3-b5. Peter's game with Vishy
in Wijk aan Zee continued 10.Nb3 d5 11.Kb1 Bc3 12.bxc3 h6..."
A bit mysterious GM-comments for me woodpusher, now how is that a6-pawn going to
disappear exactly, to make Nc3-b5 possible? But Shipov analyzed this in Moscow
with the likes of Spasski, so I suppose he's right... He does not discuss other
moves besides 10.Kb1 and 10.Nb3

After winning this game Shirov went on to win the tournament. He writes about
this game in New in Chess magazine: "17.b3! At first I thought there was nothing
wrong with 17.Bd3 Nf4 18.Bc4 Rc4 19.Bf4 exf4 20.Qb3 winning a pawn but hen it
dawned on me that Black would get excellent play after 20...Qc7 21.N1d2 Rc2!.
17...Na3! Another strong move after which I couldn't believe my eyes when it was
played. The knight goes to the edge, it's not even attacking White's pawns but
its activity is not to be underestimated"
So the move to avoid is 17.Bd3, the move to find, and all three play this, is
17.b3. The thing I'm not sure about is whether 17...Na3 is the only move here,
Albert's S&D 6_7 shows that in its lines from ply 16 after 57 minutes, Pro Deo
does not and continues with 17...Na5, S&d 6_7e3 is between that, it shows Na3 at

I experienced a glitch here, in I think the Chess Parter GUI, the time as you
can see got reset after 6 ply, starting from zero again on ply 7 after a blank
line. In Pro Deo's move window all plies before ply 7 now got a time of
00:00:00, very odd! The search process seemed intact though.
Lots of lines I admit but my conclusion: overall the three engines/styles seemed
to be largely in agreement. S&D 6_7e3 did not do too poorly!
