Is this the way you are supposed to play AK if you don't hit anything on a dry board?
Hand converted with online PokerStrategy.com hand converter:
$0.05/$0.1 Fixed-Limit Hold'em (10 handed)
Preflop: Hero is UTG1 with A:h, K:d.
UTG folds, Hero raises, 6 folds, SB 3-Bets, BB calls, Hero caps, SB calls, BB calls.
Flop: (12 SB) T:h, Q:d, 4:s (3 players)
SB checks, BB checks, Hero bets, SB calls, BB calls.
Turn: (7.5 BB) 8:c (3 players)
SB checks, BB checks, Hero bets, SB calls, BB calls.
River: (10.5 BB) 8:h (3 players)
SB checks, BB checks, Hero checks.
Final Pot: 10.5 BB.
So the risk of getting checkraised is considerably low and maybe BB folds a hand like 55 66 77 that he just called once to see what'S gonna happen on the Turn. SB couuld still have AJ or made a loose Play with KJs Preflop. Unless he hit 88 he'll be just calling again. SB could also have JJ 99 or ATs (though it would be too loose Preflop but who knows)
