Can anyone elaborate on this take, I have actually passed it in one second without considering taking.
Factors I have weighed :
- race is equal but we are on the bar and white has plenty of anchor potentials next roll.
- we may dance on next roll and even if we don't we will play one man behind without any threat and have slim chances of running away
- white has to clear 16 point but she is not in a hurry.
- we have a decent board but white does not necessarily has to attact us to win the game.

I will appreciate any comment on this one, thanks

OK, let's start with the simple Position-Race-Threats matrix. Race is even, so nothing there. White's position is clearly better. Black's on the bar and White has partially escaped his back checkers. How about threats? Not so much here. White's threat is to make a third inner point, which gives him a slightly better board. Black is a 3-1 favorite to enter if that happens. If White doesn't make a new point, Black is an 8-1 favorite to enter.

I like the double because a good roll for White followed by a bad roll for Black -- White makes a point, Black dances -- will get to a position that's a pretty clear pass. But suppose White makes a point and Black just enters, say with a sequence like 5-3 making the 3-point and 5-1, entering but doing nothing special. That looks like a pretty easy take even though it's a reasonably good sequence for White.

White's problem is that he's only starting with a 2-point board, which means there will be a lot of chances for things to go wrong for him. Sometimes he won't make good points so quickly, and with the race being close, Black will have plenty of chances to do something.

I think the mistake you're making here (a very common one) is assuming that what looks most likely is what will actually happen. White's pieces seem well-placed, so it's easy to assume that he'll just keep filling in points and Black will be crushed. But this variation will actually be pretty rare. The fact that the race is close will give Black lots of unexpected chances.

A great exercise would be to play this position out 50 to 100 times and watch what happens. We did this all the time in the pre-bot days and it's enormously useful in showing how variable positions are, especially when the home boards are weak. Try it and I guarantee it will open your eyes to why this is a take.

The race is still even and he still has some potentially awkward contact with that 16 point
