Former European champion Joe Dwek won at Crockford’s last week by beating Charlie Witz of Chicago in the finals. In the semifinals, Dwek defeated Gino Scalamandre, also a top-ranked competitor. In other results at Crockford’s, Hermes Michaledes won the first consolation and Peter Gold took the second consolation.
The diagrammed position occurred during a key game early in the 21-point finals match, with Dwek (White) leading 8–6. Earlier in the game, Witz (Black) had doubled and then been redoubled, so he now owned the cube at the 4 level.

| Black to play 5-2. |
When attempting to save the gammon, the standard procedure is to move your men into your home board as efficiently as possible. This can be done by bringing men exactly onto the 6-point. Moving men deeper into the home board wastes pips which should be used in the outfield instead. With this in mind, Black played 11/6, 8/6, stacking two more men on the 6-point.
Unfortunately, Witz’s strategic evaluation of the position was faulty. With nine men still outside, Black had, in reality, little chance of saving the gammon simply by running home. Black should resign himself to being gammoned unless he gets a hit, and play accordingly.
The correct play is 9/4, 6/4, strengthening Black’s home board. Black must prepare to contain White in case he is able to hit him later on. In the actual game Black did indeed get a shot and sent White back. Unfortunately White was able to escape because Black’s home board was still weak. In fact, despite the hit, Black narrowly averted being gammoned — the one outcome he mistakenly tried to avoid.
