TOPALOV 1111111 FULL MATCH (21.gxf7+), Fritz 9 delta2 = -0.05

MAT: Ha! gxf7+ stops matching at 17 ply---but even an 8-core machine
MAT: wouldn't see that in time!
MAT: 
MAT: This may look strange, but the point of using continuous, smoothed,
MAT: and flexible methods is that this should not be *too much different*
MAT: from if it had "delta = +0.01"!  But the "MATCH" verdict /is/ important!

TOPALOV 1111111 FULL MATCH (22.Be6+), Fritz 9 delta = 0.03

MAT: Full match, but the surprising 22.f4! made up a lot of ground!
MAT: It pulled within 0.03 at 17/17, from well back.

TOPALOV 0000000 NON-MATCH (23.b3), Fritz 9 delta2 < -2.27
TOPALOV 1111000 PART MATCH (24.Rhg1), Fritz 9 delta = +0.04

MAT: This one, on the other hand, is more of a head-scratcher,
MAT: since it matches at 11-14 ply and again after th 16-ply round
MAT: in multi-line mode, but not in single-line mode even at 17 ply(?)

TOPALOV 1111111 FULL MATCH (28.Qxh7), Fritz 9 delta = 3.01

MAT: My conclusion from this and other similar cases is that the
MAT: single-line PV hash evals are labeled MAT: with /authoritative/ depth
MAT: info while in the single-line mode.  Then in the multi-line mode, they
MAT: persist when other evaluations for that position try to replace them.
MAT: Whereas, if only multi-line mode were done, more replacements would
MAT: succeed.  I will wait to see if a change happens after 18/18 his time.  
MAT: (None did; for 19/19 29.Nd3 went up 0.08.)  But for now:

TOPALOV 1111111 FULL MATCH (30.cxb3, forced!), Fritz 9 delta = 6.97

MAT: Well, this move 31 definitely has to be re-run with the older methodology,
MAT: for comparison, where I do 10-line mode throughout, and in
MAT: single-line mode throughout.  Officially:
