See here:
(Sieh her)
Here an short experiment:
I less Dj 7 pondern to depth 18 on a "slow" machine:
Eduard - Deep Junior 7 [E46]
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 0-0 5.Bd3 d5 6.cxd5 exd5 7.Nge2 Re8 8.0-0 Bd6
9.a3 c6 10.Qc2 Bxh2+ last move, now I play: 11.Kxh2 now play Dj7 on a slow
machine Sg4+ 0.00/16 2:03 Im to move again 12.Kg3 now an ponder from Dj7: Dg5
0.20/18 1
Here the thinking line by Dj7 after Qg5, I have it copy to clipboard:
Eduard - Deep Junior 7
rnbqr1k1/pp3ppp/2p5/3p4/3P2n1/P1NBP3/1PQ1NPPK/R1B2R2 w - - 0 1
Analysis by Deep Junior 7:
12...Qg5 13.f4 Qh5 14.Bd2 Rxe3+ 15.Bxe3 Nxe3 16.Qd2 Nxf1+ 17.Rxf1 g6 18.De1 Dg4+
19.Kh2 Sd7 20.Th1
= (0.20) Tiefe: 18 00:07:19 169209kN
In depth 19 and 20, Dj 7 ponder the move 13. f4 too with a plus score for white!
