In Response To: Bob Koca Interview--A Must Read (phil simborg)

Good interview, a few points:

4) Certain styles of play will fare better than they really should. For example suppose that a player’s weakness is that he takes races that he should be dropping. He will be penalized for the incorrect take but then will get to play out a race in which the plays are relatively simple. He may very well get back what was lost by getting to play out the race.

Point taken but the bottom line is not true, he will not 'get back what was lost by playing out the race'.

5) The goal of the game is to defeat your opponent not play with the lowest ER possible. This is related to points 2 and 4 above but there is another factor here. Suppose that a player has a choice between two plays that are about equal in equity, For example maintaining contact or racing. If your goal is to play with a low ER you should race. After the other play you will probably make more errors but your opponent will also. Thus players who play a complicated style may have a worse ER than someone who plays a simple style yet be more likely to win matches.

Isn't the goal of the contest to play with a lower ER than your opponent, not the lowest ER possible? If that's the case then you'd still maintain contact.

What is the take point at 4 away/12 away if the trailer is redoubling the leader? How long did it take you to calculate that in your head? How did you calculate it…what is the formula? (ex says it’s 31 percent but I have no idea how to get there over the board!)

UBK suggested this might be the gammon adjusted take point, it is not. Assuming you know a few things this take point is easy to figure out. What do you need to know? Either a match equity table memorized out that far (not likely) or Neil's numbers (likely). Using Neil's numbers here's what you get:

• Double/pass gives -4 -10 or 82% match equity
• Double/take/lose gives -4 -8 or 74% match equity
• Double/take/win gives 100%

You'd be risking 8% to gain 18%. Your take point equals (risk/(risk+gain)) or 8/(8+18) = 8/26. This comes out to 31%.
