At a glance, it appears e6!! is the Killer Move...will have to look at this one.Mark Uniacke wrote:Sorry for not posting a new position earlier, anyway....
Here is another interesting position which I wonder if anyone knows something about?
[fen]r1r3k1/p3bppp/2bp3Q/q2pP1P1/1p1BP3/8/PPP1B2P/2KR2R1 w - - 0 1[/fen]
Now with white to move its clearly an attacking position, so how can white take advantage of this and deliver a killer blow?
I am sure with your silicon friends you will solve this one, but for the complete solution please let us know the players and year the game was played?

I would think this position would be hard for programs. I've no idea who the players are?Cubeman wrote:I have seen this positon before in a magazine.1 e6!! is the killer move.I even had Hiarcs 9.6 running on my iPaq hx 4700 under styletap and let it analyze.Came up with the following info.
D 10 1400s -0.62 e6
D 10 e6 3/46 15041672N
Then I left it on longer and got
D 10 1447s -0.32! e6
And a bit longer
D 10 2129s -0.32 e6 gxh6 gxh6+ Kf8.
Later on it was showing a 0.00 evaluation and I remember seeing a +0.32 evaluation when it had got to D 13 but I was half asleep and could not be bother recording all the other info.The whole line runs somthing like this.
1 e6 gxh6
2 gxh6+ Kf8
3 Rdf1! f6
4 Rg7 Qxa2
5 Bxf6 with a Mate in 6.
There are alternatives for Black on move 3 and 4 but involve massive sacrifices to avoid the immediate Mate.
Well done Hiarcs 9.6, for comparison PocketFritz2 could not find e6 even at D=15 and many hours later.
Why Qxg7+?, I believe that would be losing, you need the g-file open for your R on g1. 1. e6!! forces the issue.Ted Summers wrote:I was thinking on 1st glance Qxg7 followed by e6.Terry McCracken wrote:At a glance, it appears e6!! is the Killer Move...will have to look at this one.Mark Uniacke wrote:Sorry for not posting a new position earlier, anyway....

Wow, that is very impressive of Palm Hiarcs, even the PC programs have some trouble finding the right move which is indeed e6!!Cubeman wrote:I have seen this positon before in a magazine.1 e6!! is the killer move.I even had Hiarcs 9.6 running on my iPaq hx 4700 under styletap and let it analyze.Came up with the following info.
