playing in a live £50 rebuy comp, 29 runners normally takes £5k this comp eventually took £4,900
blind levels during rebuy are 50-100/100-200 then 200-400 all 30 min levels, starting stack 3,000
i have just moved tables and the blinds are 200-400,
im on the bb with

with 6,700 chips there is an utg raise to 1,200 and 3 limpers i elect to flat call on the bb hopeing to win a monstor,
the flop comes

im 1st to act and decided to try isoloate the bare A or some idiot with AK and push my entire stack in 5,500
is that the correct move? because after the hand i was told by 3 players that i should of check called and hoped for a non spade turn ?
the outcome doesnt matter its just if i played it right im intrested in,
thanks for your advice, - stu
