This hand actually occurred in a LH SNG, I raise preflop with AKo and flopped the nut straight. I flat called on the flop and then got the dream card when the 8 fell, giving the two other players the idiot end of the straight. My question is whether or not the slowplay is a good idea. It worked like a charm, but with one player having an oesd, and the other having the lower straight on the flop, they probably would have paid a few flop bets along with what I did get on the turn and flop. Anyway, just looking for some ideas about slowplaying the nuts here.

P.S. Even though this is a tournament, I am still learning the ins and outs of limit, so I would appreciate comments about how to play this in a tournament, and also if it occurred in a ring game. I don't really think it would be that different, because we still had a full table, and the blinds were only in the third level, so it was still playing like a ring game, but if anyone has a different thought about that, I'm open to hear it. Thanks.

never played a limit tourney but I think you played this hand great as you got maximum value. If you raised the flop, they may have slowed down sooner.
