When you’re down to your last few chips and can play for just the cost of the ante or blind, you should often wait to rebuy until after the hand! That’s because there are no better pot odds than to be able to see the showdown for free with everyone else at the table matching your money with their antes.
If it’s a blind they’re matching, only some will voluntarily call. But, even then, the point is powerful: Other opponents may knock each other out of the competition, while you remain to see the showdown.
You’ll often arrive at the showdown with hands you couldn’t have afforded to call with if you’d had more money. This means you have an extra opportunity to get lucky and “draw out” — and that’s worth enough to defer your rebuy until the next hand. — MC
