When people suddenly bet way more than on previous streets (in relation to the pot of course) they usually have a monster.

It's true 9 out of 10 times.

Id call as well, it looks kind of odd........

When I read the hand I was very worried about quads as he did play it exactly like he had quads and he is going for max value on the river. You have to ask yourself, "Why did he bet the flop, bet the same amount on the turn and shove the river?" When you think about it, many weak players will lead into the raiser with top pair. His bet on the turn is actually pretty deceptive as it's hard to say if he has nothing or a legitimate hand. When he shoves the river though, you should be thinking, "Would he do this with 77-99?". Chances are, he knows enough to realize that his hand is not that strong, especially when you are calling down. If he had a hand like that, I expect he would make another small bet on the river. Shoving is a strong indication he has quads.

However, it is unlikely he has QQ, KK or AA since he did not re-raise preflop. If he did have one of those hands, he would probably bet larger on the flop as well. So your TT is very strong on this board. Since it's a live game, you have the luxury of being able to watch his body language. In a situation like this you need to think really hard about exactly how he acted when he put the money in. I think live this is a fold I might actually make but online I don't think I ever would. This is just an unlucky spot because it is mathematically very unlikely he has quads, but as played it does make the most sense that he has quads. I don't mind your call. In razor thin spots like this you have the added value of being able to see his cards when you call and you gain some valuable information for later.
