Take a wild guess at which one I encountered OTB and which play I made. Obviously position 1 and the bar point respectively :)
Needless to say, this was not my biggest mistake in the 17 point match, but it surprised me as I was confident that my play was the best.
I still don't quite get where that swing comes from. Stick, what do you refer to when you mention duplication/diversification? The 62 of oppt being better after 13/8 in the first example compared to the second? Or the fact that 5s escape and 6s are used to make the bar after 13/8 in the first example, but 6s are used for both in second example? Or that 5s both slot the back of the prime and escape after making the bar in the first position? Or all of the above? Or something more? :) Just curious about what I missed in this position.
Obviously, in both positions, we have more numbers that complete the prime after the 13/8 play, more numbers that can slot the final point if he dances (but with a higher risk) and better coverage if he jumps out with 61 52, compared to the 62 after making the bar.
