good spot to semibluff?

[str1130]

PokerStars No-Limit Hold'em, $2.50+$0.25 Tournament, 75/150 Blinds (9 handed) -

UTG (t1960)
UTG+1 (t3550)
MP1 (t4180)
MP2 (t4793)
MP3 (t5730)
CO (t13335)
Button (t3175)
SB (t1320)
Hero (BB) (t3231)

Preflop: Hero is BB with 7s, As
UTG calls t150, 4 folds, CO calls t150, 1 fold, SB calls t75, Hero checks

Flop: (t600) 6h, 4s, 8s (4 players)
SB checks, Hero checks, UTG checks, CO bets t450, SB calls t450, Hero raises to 3231 and is all-in

Is a checkraise all-in good here? I figure that my equity is pretty good with 12 or so outs, and if the big stack in the cutoff calls, i have a good chance to double up. plus i think the SB is calling no matter what happens after he calls the initial bet.
good spot to gamble?

if you are sure both are calling then its not the best spot.
You're not short enough to have to do that yet. The power of the semi bluff is that above your normal equity in the pot you add the fold equity that make this move very profitable.

Few more comments, depends how the co play, I can see shoving here PF as an optional play. Though if there is a chance he'll call with A8-AT then checking is far better.
You should consider leading this flop. its much more likely to hit your BB range then the CO's limping range.

I don't hate this move though, with 12 outs + possible A outs you're never is such a worse case if called.

As usual, I'm in agreement with these points.

The way it looks the guy who leads out probably isnt folding, of course that is without reads. The all in to me atleast looks very transparent what your hand is. AI pre looks kinda spewy, cause risking your stack probably isnt the best move since there is no antes yet.
If you are looking to semi bluff I think raising here to 1700 looks alot stronger then shoving imo.

I like this move. CO's bet could be just the attempt to steal, SB is short, and hero has up to 15 outs.
