Lukie:

sorry, but you definitely lost value on this hand. Hell, even a minimum raise on the flop would dramatically build this pot.

His bets say to me here "I have an Ax, maybe even AK. I think I outkick you, so I'm gonna valuebet." However, if I'm him, I'm not gonna get scared by you popping me back to $45 on the flop.

If I'm a donk, I'm going to be totally ok with you popping bets at me that are 1-2 to 2/3s the size of the pot unitl eventually I lose everything.

However, if I'm not a donk, then I'm going to raise you on the turn anyway.

Either way, Lukie will usually get more money by raising on the flop.
