Structure and Risk-Taking – Part 2 – The Solution

From the November 2024 blog post, here’s a pair of very similar positions that shows how an (apparently) small change in an early-game position can dramatically change your approach.

Cash game. White to play 5-1

 

Cash game. White to Play 5-1

 

These two positions show a routine situation in the early middle game. Both sides have an anchor, and the race is very close. White’s position is slightly preferable since  he has better chances of establishing a block against Black’s anchor.

White’s roll of 5-1 is a pretty routine shot and he has two obvious choices: 9/3, starting the 3-point, and 13/8 9/8, playing safe while keeping all checkers is front of Black. Of these two plays, 9/3 is slightly better; 13/8 9/8 creates a big stack which will prove awkward in some of the upcoming variations. In the middle game, we try to avoid creating big stacks unless alternatives are really weak. There’s nothing structurally wrong with 9/3, so it’s a better play here.

Speed versus Structure

Note: All ‘cash game’ problems assume the Jacoby Rule is in effect. That is, you can’t win a gammon unless the cube has been turned.

Who is a favorite? And why is this, in fact, a problem?

Containing a Checker on the Bar

Cash game, White owns the cube.

White to play 3-2

Problem 176 is an example of a type of position that arises fairly frequently, especially at the tail end of a mutual holding game. Black probably held White’s 5-point for a while, then left either to hit a shot or to create a spare on the midpoint. White scores a lucky hit, and now Black is stuck on the bar against a 5-point board.
