Reads: <font color="blue">Villain is 41/17 over a couple hudred. He's donked into me on the flop the last 2 times and I've folded. A couple orbits ago, he put 5 bets in pf w/ TT and 100bb. He opened MP, CO called, I 3bet btn, he min 4bet, I shove, he calls. AA holds. What's your turn play here? And if you flat call, gimme a plan for some rivers.</font>
