game 1, move 0: Herd 5-1

[diane]

Welcome to fibsboard match 12 all, I hope our newest worthy opponent enjoys this beat..I mean match  

Ok - we are off..I met with stiefnu on fibs and agreed his opening 5-3 move would be the standard one. So - to ease you gently in... how would the herd like to respond?

Somehow I was asleep at the switch, and I missed this play.

I'm not sure how the tie was broken, but splitting is much better than slotting here.  Slotting with an opening of 51 is doubtful, but with the  opponent having a second homeboard point it's probably a blunder to slot.

The problem with slotting with 51 is that there are no builders, so even when you're not hit you can't cover the blot often enough to make the risk worthwhile.  Add in the additional danger of being on the roof against a two point board and slotting is severely counterindicated.

Spoiler

Splitting is the right play, but "blunder" is too strong a word to describe slotting.  Splitting wins only a few more games, has the same gammon rate, and only loses a few fewer gammons.  The difference between the plays is only a third of a percent MWC.  I wish all my errors were this small.
