I had the win in this game but blew it but interestingly the big 3 have very different moves to suggest.

I understand the Stockfish & Komodo moves but Houdini befuddles me. I don't like it. I like Komodo's suggestion as it gets right to the point and keeps the initiative going.

What happens if you give them more than 30 seconds each? :wink:

For example, Cfish quickly switches from h4 to Rg4:

I forgot to mention I only use 2 threads as I have a laptop and they suck at cooling. I did not let it run 30 seconds. Just to a depth of 25 or so. Let it run for an hour, a day, a week, a month. Will it be the same or change again too.

I just gave a snapshot to show where in general they will go because when you really think about it there is no absolute best move and yes it will change and my moves indicated are not absolute. The machine's choice was much better than mine and I would have been winning if I went their course so it was absolute compared to my little monkey brain.
