AI Shoulda Woulda Coulda and more river decisions

Ah man!!! I should have bet on Chris Allen to win American Idol like I had mentioned in a few posts early on. 8-1 would have been a nice price to get. Again, I'm not shocked that he won and quite frankly expected him to win. Oh well..

As we know, river decisions are the hardest so here are a couple more.

Villain is a 31/21/5.3 guy over 70 hands.

Full Tilt Poker $0.25/$0.50 No Limit Hold'em - 5 players - http://www.thehandconverter.com/hands/129219

Hero (CO): $54.40
BTN: $98.15
SB: $51.00
BB: $26.10
UTG: $74.25

Pre Flop: ($0.75) Hero is CO with 2d Ad
1 fold, Hero raises to $1.75, 2 folds, BB calls $1.25

Flop: ($3.75) Td Ks As (2 players)
BB bets $2.50, Hero calls $2.50

Turn: ($8.75) 5h (2 players)
BB checks, Hero checks

River: ($8.75) 2s (2 players)
BB bets $7.50, Hero ??

What beats me? 2 pair Aces, spades, straight (not likely)

What do I beat. I now beat KT, non 2 pair aces or a bluff.

What do you do?

Flop: ($2.50) Tc 5c 9s (5 players)
SB checks, BB checks, UTG checks, Hero bets $2, BTN calls $2, SB folds, BB folds, UTG folds

Should I have been re-raising on turn? Turn min raises are typcially pretty strong.

What do you do?
