10-10 plays best either heads up or multiway. It plays the worst against 2 or 3 opponents.

This concept of TT (and JJ) playing poorly against 3 or 4 opponents is grossly misunderstood. Posters have been rehashing some of Mason's comments about this situation without giving it any independent thought. I don't even think Mason has explained it very well. The key factor in deciding whether TT is in good shape against 3 or four opponents is what your opponents are playing.

TT (and JJ) plays great against three opponents when those opponents hold "legitimate hands" like A9s, 44, and 87s (43% equity in a simulation). However, they play much worse against "trash hands" like A9o, K2s, and Q5s (33% equity in a simulation).

Wben you've got TT (or JJ) in late postion and there are limpers ahead of you, you need to know what your oppponents are limping with. If they are inclined limp with AJ and KQ, you're in bad shape and should consider limpimp behind. If they are more inclined limp with smaller pairs and suited connectors but would have raised with the big offsuit cards, you should raise.

When you've got TT (or JJ) in early position, you need to know what your opponents will cold-call raises with. Some players will always call a raise with any pocket pair or suited connector but will always dump big offsuit cards (except AK). Others will call with the big offsuit cards and always dump the suited connectors and some of the pairs. If you're playing against opponents who will dump the big offsuit cards but call wtih the pairs and suited connectors, you should raise. If they'll call with the AJo/KQo, then limping is best.

The idea that TT (and JJ) plays badly against 3 or 4 opponents is wrong if taken at face value. It depends upon what your opponents are likely to be playing given the pre-flop betting action.
