You need A-A, K-K, Q-Q, J-J, A-K, or A-Q suited, to raise, reraise, or cap it. In short, just put more money in. If you have 10-10, 9-9, 8-8, any suited blackjack or suited 20-point hand, you can call one bet. But if it’s raised to you and you can’t reraise, you can’t call two bets cold; you have to fold. After the flop, you can continue if you have top pair (or could beat top pair), an open-end straight draw, or a flush draw. Anything else, you are done with the hand!
