A value bet might as well be all in if he's experienced - it will be seen as a very intimidating bet, and you will look very strong - even with a loose table image... K anything here is most likely good in his mind. He either has a Q, (suited connectors maybe? just to play back at you with 2 to 1 odds
with your loose image thinking MP is going all in) or a pocket pair to be in for 20 preflop - since there was a raise and re raise in front of him - I'd think pocket pair.
I would have said all in, as soon as I could - in live games this can be seen as missing a draw all together, and just trying to take it down... whatever you do, don't look at your opponents stack to see how much you can take or double up off him... this is such an easy tell in a live game when people have the nuts - and is done unconsciously all the time. 3 of the quads on the board is harder to get paid off then pocket pair quads, I wouldn't value bet personally - but I do change it up a lot. If Im in a ballsy mood, I check it and try to get him to hang himself. But if he doesnt have a K, you're not likely to get anything out of him.
