When you snuggle you often wind up giving blocks away on your hammer or maybe two; sometimes you wind up in the kitchen just for good measure.
If you must snuggle, do it only when you have the hammer, repeat, only when you have the hammer and as Dale Williams advises only on the 3rd block so your opponent only has one chance to make a mess of you.
Books I’ve read say only to snuggle in the 8’s and Glen Peltier would agree with that, because he teaches players how to hit a low snuggle firmly on the side knocking your block off the board and rolling the opponents block into the kitchen. However, some of the games all-time great players maintain the only place to snuggle is in the 7’s, because the lines are further apart and therefore harder to edge your block off the scoring surface.
Snuggling can be a great play late in a game to keep from being put in the kitchen.
You really have to decide what will work for you; keep in mind how dangerous the play is, this is one of the areas where you probably don’t want to do what I do and that is I snuggle on almost every block late in a game where I have the lead or need two blocks to win or put my partner in position to win.
Now and again I get burned.
