What do you think when this happens?

I bought in with a 40BB short stack here just for the hell of it. This is my 2nd trip around the blinds.

UTG bought in for $10 and has only played 4 hands folding two flops.

MP1 bought in for $10 a few hands before I came in. Calls a lot of pre-flop raises and then folds if he misses.

SB bought in for $40 just 4 hands ago. Has seen some flops but no rivers.

At the time I was thinking that I wanted to see how many were interested in the flop before I comitted anything significant to this pot.

I was totally confused about what was going on. I've never seen this much interest in a paired board on a real money table.
