Re: Old Uri test position
After playing g5 stockfish1.5.1 gives at depth 23 a score of -2.94. So probably both moves are good.

Re: Old Uri test position
I'm getting stuck after something of a fail low for 1... Re8, from +2.37 to 1.35, maybe the fail low is more an illusion and the score would just go up again but in other cases I also saw this drop but not to so low a score, unfortunately it did not help in getting g5 as an alternative.

After 846 minutes still pondering 2. e4 (2/23) which probably means that the search depths are too high when the main variation changes, or 2. e4 is now very close in evaluation, or something else...
Finding 1...g5 however did not succeed also with build 82.

More than 24 hours and the machine was still thinking about 1... Bh5 at fifteen ply so I gave up, 1... g5 is still far away down the move list.
But after 1... g5 Rainbow Serpent build 82 gave this:

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
