Is this good STS test result?

[Jouni]

I gave engine 60s for each position, because my PC is slow.

Engine is XXXXe4w32.

Hard to compare because I do not know your hardware, but an excellent result.

I would be interested also to see the engine output, and especially so for the problems that were missed.

Hi Jouni, Considering an engine being given 60 seconds per move and a limited hardware, this is extremely good result.

I'm assuming this is kind of improved Robbolito? then no doubt it's close to perfection. Still very little knowledge not being displayed due to limited time and limited hardware.

This results confirms that STS tests are good for quick-testing many freeware engines rated 3000 and below.

Ra3 is missing from solution. It's better than Kh2 and Kg1
