An absolutly WORLD CLASS play in my opinion......your thoughts please

[skin city]

ok heres the deal, i live in vegas and the other night i was playing the 2am tourney at binions, and there is a guy at my table who has been making some pretty good reads, some nice plays, etc. and then about 2 hours into the tourney, the fallowing took place:
we'll start with the players and their chip stacks so you can really get a feel of what went down.
The first player is in seat 3, his name is Andy Nguyen. he is actually a dealer at the horseshoe and he also won a wsop braclet in event #1 (i think) in 2005 (look it up)
andy has around 4500 chips.
the second player, i dont know his name and have never seen him before, so ill call him solid player or (SP)
SP has around the same chip stack, maybe 5000 in chips, and he is in seat 7
OK, heres the hand and how it played out:
the button is in seat 1, blinds are 75-150. all players fold around to SP in seat 7, he calls the 150, one more caller in seat seat 9, then it folds around to andy on the BB, andy raises to 400, then back around to SP, and SP makes the call, seat 9 folds.
we get heads-up to a flop of Ac 8h 4d......andy, acting first, fires out 600....SP calls
the turn card brings the Ks....andy then fires out a bigger bet of 1600 chips. (at this point im putting andy on a big ace, probably AQ) now here is where the hand gets interesting....SP starts talking to himself and goes into the tank for 40-50 seconds and peeks back down at his cards and says to andy, "man andy i feel like you got it, i got a nice hand, but i feel like you got it" he then says to andy,"if i fold will you show me?" and andy being a generally nice guys says "yeah sure ill show"
SP then turns his cards face up to reveal pocket 4's for bottom set, and then says "you got it andy, nice hand"
andy stands up! and says "What!!?? your folding??!!" "your really gonna fold a set!!??" he does fold and andy says ok ill show...and turns over pocket 8's for middle set!!!!

Now ive been playing poker now for about 6-7 years in vegas and i watch it all the time on t.v. and i dont think ive ever seen a laydown like that, especially when you consider that there wasnt a HUGE amount action pre-flop, there was no draws on the board, and the fact that 9 out of every 10 players would have played an AQ or maybe AJ the exact same way, (raise from the button in a limped pot, make a continuation bet on the flop when you hit top pair, and then raise the price when the "scare" card being the Ks hits the turn)
another thing that makes that play so amazing was the fact that andy's bet on the turn wasnt like it was putting SP all-in and his tourney was in jeopardy!
i sat and went over this hand again and again in the past 30 hours or so and i cant figure out how the hell this guy made that read, again andy is a VERY solid player, hell he won a wsop bracelet for christ sake! and this guy totally out-played andy the whole way....im kind of still in awe and am hoping some day to get to the level, to be able to make HUGE (and by HUGE, i mean WORLD CLASS) plays like that.
am i crazy to be thinking about this hand so much? have i lost my mind? or was that one SICK ASS FOLD?????
i would love to hear your input on this and also if you have any questions before you comment, ask and ill try and remember any other details i can.....
thanks guys for your input
