Stars 3r. AK in SB with action in front of me

[I StackManz]

Sup 2+2. My first HH post so forgive me if I mess up the format or anything.

Ok im in the 3r on stars 603 places pay and 300 odd left. Got avg stack of about 50k when the following takes place

Poker Stars, $3 + $0.30 NL Hold'em Tournament, 1,500/3,000 Blinds, 9 Players

CO: 42,804
BTN: 38,520
Hero (SB): 56,076
BB: 97,527
UTG: 26,360
UTG+1: 7,484
UTG+2: 14,403
MP1: 52,633
MP2: 86,231

Pre-Flop: (7,200) K A dealt to Hero (SB)
2 folds, UTG+2 raises to 14,103 and is All-In, MP1 calls 14,103, 3 folds, Hero raises to 55,776 and is All-In, BB folds, MP1 calls 38,230 and is All-In

Basically I wake up with AKo in SB. UTG+2 who lost a big pot a few hands ago open shoves their remaining 14k. MP1 nexts to act flat calls.

Based on history at that table, MP1 limps small PPs and calls reraises, or just flat calls other peoples raises never actually reraising.

Folds around to me and I shove for a few reasons.

1)AK has to be ahead of the UTG+2s range
2)Thought I have FE against MP+1 (not sure now i think back at it)
3) If I get called I still have some equity

So question is. Is shoving here good or bad? Any alternatives to shoving?

Thanks
