50/100 big big pot

[gakn29]

I dont play much limit so I like making sure Im not doing anythign too stupid here. Ok so heres the deal its a 50/100 game in Vancouver last week during the BC championship and Im in BB on a pot that has 4 posters, I decide to call with any 2........is that bad? ok moving on its raised UTG and 7 calls to me I call with 74o.

Flop 7d4d2d I bet UTG raise fold to sb who calls I 3 bet UTG caps sb calls. is the 3 bet spewy or no?

Anywyas turn pairs the 4 I lead UTG raises sb fold I 3 bet UTG calls

River 8x : I bet he calls.

Was this good or did I miss bets or spew the flop or what?
